animation

[coral python]

Hello all,

I'm trying to use a custom hand mesh in the place of a VR plugin's hand mesh. However, the skeleton for the plugin's hand has 3 different skeletons in one- a default one, a hand_l, and a hand_r. The physics asset uses hand_r. When I import my hand mesh using the skeleton, it uses the default one at root. Is there any way I can switch my hand skeletal mesh to use the hand_r root, so that I can use the physics asset?

Or alternativelt, does anyone know if I can copy this hand_r body to be at root?

[limpid oak]

Hi there. What is the easiest way to open a players hand (all bones extended)? I am doing hand IK to touch a wall but the fingers are curled still. I want the palm and fingers to be flat against the wall. Any ideas?

[quaint crescent]

Is there a way of setting the Smoothing Time from the Animation Blueprint?
Reason I ask is because I want to have a Smoothing Time when using the blendspace normally, but if I leave it switched on all the time then when I need the animation to jump to a different point in the blend, it smoothly interpolates over a frame.
Disabling Smoothing Time fixes this, but then the animation looks jank during normal playback.

[rough bluff]

Just a quick general question, but how many Morph Keys is considered too much?

[pliant jolt]

How do i Limit the Rotation in Two bones IK(Print)? The left arm is Ok, but the Right arm is wierd sometimes, (video)

The Limit is to not Bend in the wrong way

[limpid oak]

You can limit rotation of bones with the fullbodyik node and per bone you can set rotation constraints

[novel viper]

Hello. I have a super strange issue. I made a new montage. But for some mysterious reason no matter at what speed I set the montage or even the animation within the montage, when the montage is played it's always the same speed. I have even tried hooking up the montage directly to the output in the anim graph and still it always plays at the same speed. Does anyone know what in the hell might be causing this?

It feels like an engine bug of some kind that breaks the animation speed settings?

But I've never encountered this before.

[mortal wave]

Hello all, having a bit of an odd issue, an added animation curve into an animation sequence does not show up in the Animation Blueprint when using GetCurveValue, does anyone know what might be happening here?

[slow brook]

So let's say I have a a amarture thats made in a way where I only want the bot to move when it's actually in a step motion so making a step

is there a way to do this or would I have to manually set walk speed to and from 0 at the relevant points on the walking anim ?

[pliant jolt]

Where is this node?

you talking about the constraint? i believe its normal.. its limited

[naive mountain]

Why does Lyra have so many branches checking if TurnYawWeight = nearly 0, when you can remove that curve completely and check if RemainingTurnYaw = nearly 0? Seems pointlessly redundant with zero upside. These 2 curves are used for the Turn in Place logic and never exist apart from eachother.

[pliant jolt]

Fixed, the Joint of the Right Arm was in World Space, change it to Component Space, and the job is done

[tropic lava]

hello, anim bp beginner here. is there any way i can blend an animation only in one state? theres this attack montage that i have but i want it to blend only for the falling animation and not the walking one, is that doable?

[slow brook]

Anyone know the best stride length for a walk cycle of 30 frames and 150 cm/s ?

[naive mountain]

So all logic breaks beacause of some way the curve data is communicated. Cant be bothered to drill down on an extremely minor thing.

[pliant jolt]

i dont know how you want, but from what you said, its just a Blend Poses by Bool, and make the logic in this Bool to perform only when its falling and you are attacking.

[honest ruin]

Hey, using "Enable Animation Budget" in event beginplay, the animations on my character don't work. However, when I activate it through an input, it works correctly. What could be causing this issue?

[slow brook]

Anyone know what would cause the player to stay in air even after I've detached them from the specific Enemy AI that they were attached to

[last merlin]

is it possible to time an animated texture in a sequence from a midpoint of a video file? When I tried to work on this years ago, I had to use an image sequence to get exact frame-specific timing.

[zealous jewel]

could someone tell me what the purpose of the post processing animation blueprint is? What sort of things is it suitable for?

Also, what's the purpose of this CR_Mannequin_Procedural rig in the starting 3rd person project? It runs inside the post processing blueprint of manny/quin

[limpid oak]

When you add a control rig to an animation blueprint, within that you can add a “fullbodyik” to the blueprint to then specify your target location and add per bone restrictions

[merry loom]

It is usually for when you have secondary bones(tweaker bones, Twist bones, muscle bones, jiggle bones …. whose pose is determined by the primary bones ( arms and legs.. torso….) so post process basically uses primary bones to drive secondary bones to achieve better shape and deformation

[zealous jewel]

Thanks!

what's this bug icon / what does it mean?

[viscid willow]

that means there is an interpolate on the resulting value of the node. If you right click the node you should be able to see options to edit or remove the interpolate

[zealous jewel]

Thanks, it seems like this thing is "visual debug", can be turned/on off by right clicking on the result node. Didn't try right clicking on the result, just the node itself.

[viscid willow]

oh you're right, the bug pin is for the interpolate iirc

[zealous jewel]

I'm trying to understand the inertialization implementation in unreal... I get the idea of what it's doing, but I'm not sure why you even have to place a node in the anim graph. What's the purpose of that? Why isn't it enough to set it the transition mode inside the transition setting?

[viscid willow]

There's a bit about multiple intertialisation nodes here: https://dev.epicgames.com/documentation/en-us/unreal-engine/animation-blueprint-blend-nodes-in-unreal-engine#usingmultipleinertialblends

[zealous jewel]

Thanks. Hmm I'm taking a look but it's still a bit unclear... maybe it's something like this - the transitions only request an inertialization request. Then, downstream, when an inertialization node processes this request -> stores its input pose positions/velocity etc. info.

So the inertialization actually happens with respect to the actual input pose of the inertialization node? Not with respect the two poses between which I set the transition to be "inertial" ?

[snow shell]

does anyone know how this bug is caused? it never trims the first frames, it always ends up deleting some random frames or sometimes (like in this case) only keep a single frame

I just want to crop a few frames t the beginning.

[wooden arch]

is it possible to procedurally "animate" a bone from blueprints?

[ripe gazelle]

are there any methods or tools to get a speed from a walkcycle?

or rather, how are the speed+cycle rate usually correlated?

[slow brook]

Anyone have a good way to move player between allowing them to control the looking around to the camera being fixed to when the animation is needing to be

bassically I have a the AI grab the player and I want to have the animation that the player does to be fully in control of where camera is looking

the only way I can think of doing it at moment is to turn off controller yaw thing

[limpid oak]

How can I smoothly do FullBodyIK? If I set the target the bone moves there immediately and you can get flickering . Is tehre a way I can tween/lerp to the target?

[smoky shell]

Look at how anim modifiers extract speed/distance in Lyra

[prime tide]

Hi everyone! Im trying te export particles animation from blender to unreal. I have already succesfully exported the animation from blender to fbx. The issue starts when I try to import it to unreal, all the particles are imported separately (there is no checkbox for merging separate meshes) and It just becomes a complete mess of meshes, bones and other stuff, 1000 each. Is there an easy way I can import this fbx animation a single object/mesh? I am using UE 4.27.2 as it's a requirement (Univeristy project)

let me know if more information is needed on my side

or maybe it would be simpler to just make a particle system in unreal? Really simple concept, just leaves falling from a tree and flowing to the side with the wind

im gonna try that

[ruby swallow]

why does the distance of the location in an animation (exported from blender) decrease as the amount of frames decrease? (im shortening it/making it faster). shouldn't the start/end positions on the timeline still end up the same way in unreal once imported?
edit: it was the ease in/out of the montage blend having less "to go on"

[limpid oak]

Is anyone here using Motion Matching? If so, what is the best way to speed up existing animations? For example, what if I want to speed up my turning animations?

[grim star]

Hey, guys!

I’m a programmer, so my question may be kind of dumb, but what is your favorite way to “autorig” a static mesh? Does any of them work ok? I believe rigging it to UE4/5 Skeleton would be enough.

I was hoping the new Modular Rig would help me on that, but from what I found out, it doesn’t actually do the full rig, it “just” adds the controls. I’m leaning towards just learning how to rig with the new Skeletal Mesh Editing Tools, since I’m way more comfortable with Unreal than with Blender or Maya.

Thanks!

[tribal chasm]

does BlendPosesByBool generate both input poses?

[little creek]

Hey there. I have a pretty odd system in mind regarding the ABP...
I want an animation to play from First to Last frame matching with the length of a Timer

So a 30 frame anim would play over the 5 seconds a timer lasts, that kinda stuff.

How could I set up the state machine for that...?

[viscid willow]

in your state machine, your animation sequence player node can be converted to a sequence evaluator which allows you to input a specific time and drive the animation by that time.

[little creek]

Ahh great! So I can make an RPG / MOBA like attack animation where there is an "attack rate" that slowly progresses the animation and dynamically may change with buffs, right?

That dynamic part isn't gonna work with a timer, ik, but this is the first draft of logic.
Thank you very much for the explanation!!

[pure mica]

I'm not sure if I should ask this here or in the C++ channel as it could be a problem with either.
I have a C++ class that creates a skeletal mesh in the constructor with CreateDefaultSubobject<USkeletalMeshComponent>. In the BP editor I assign a skeletal mesh to it and add a animation BP.
In game the animation BP does not run?
However, if I manually drag in the same skeletal mesh to this actor in the BP editor so there are now 2 identical skeletal meshes, one inherited from the C++ class and one manually created, the manually created one plays animation?
What is missing from the inherited one stopping animation?

[night rover]

@pure mica maybe you didn't add animation bp on the C++ component?

[pure mica]

I did. I also tried a different mesh and animBP which also doesn't work, so it's something with the C++ class

[night rover]

Show the codes and the bp

[pure mica]

This is for a VR project so I'm creating the VR hand skeletal meshes like so;

In the BP I have this;

[night rover]

So where did you exactly set the animation class?

well the BP one would override the setting anyway

[pure mica]

In the BP

that screen shot has a extra hand that I manually created, which works

the VR_Gauntlet works as expected, but the inherited one does not. I've gone down all the options in the detail tab and they all look the same. I'm at a lose, I've makde other classes this way and not had a issue

In reality, I suppose I don't need to create it in the C++ but I'd love to know why it didn't work

[night rover]

creating in C++ woud be handy if you need to reference it in the cpp land

ask in #cpp maybe, I haven't run into such issue

my abp seems to work fine with those settings, as long the skeleton is compatible

[pure mica]

Thanks for the input, I'll ask in the C++ channel

[turbid nacelle]

Hi I new to unreal engine, dose anyone have a good source for learning animation please. Preferable free courses

[cinder blade]

Anyone know a good way to manage large numbers of animation sequences for an anim blueprint?

For example, if I plan to have different move / crouch move / roll animations based on the character's equipped weapon, it seems cumbersome and wasteful to have all of the animations loaded into an anim blueprint and to have conditional logic for every single one. Seems like there should be a way to store your move animation sequences in sets that you can switch out whenever you change weapon. I know you could do this by switching anim blueprints, but I don't want to duplicate any of the state logic. I just want to swap the animation sequences they're referencing.

[trail spade]

Hi folks, I am rather new to engine and animations specifically. I have tried to look in history of the chat, but haven't found solution to the problem, yet it looks like it popped multiple times on forums with no answers also:
I am trying to retarget UE4 skel animations to UE5, but UE4 is missing weapon_r bone, so all animations on UE5 one have it incorrectly rotated. So far I have tried to add this bone in skeletal editor to match old socket transform, but still - animation preview looks correct, and in game - incorrect transform.

[zealous jewel]

In the control rig, why would I use the offset transform for a control, rather than initial transform?

[fleet canopy]

Hi, Im new to animating and ue5 and I was wondering how to loop a walking animation. I made a walking animation that walks forward a bit using a metahuman in sequencer and when I copied and pasted it to loop it, the animation started again at the origin point rather than continuing from where the animation ends. How do I loop it starting from where it left off?

[wanton slate]

Does anyone know of any good tutorials or general instructions on how to do the 2d Comic Style intros found in many games? Here is an example from witcher 3. Are they done in UMG or just sprites in the 3d plane? Any advice would be appreciated. https://www.youtube.com/watch?v=dd2gz6AxYoA

[honest bobcat]

I have 2 skeletons and a single bone that is under the root, that I want to retarget between the 2.
Specifically, I want the 2nd bone to simply copy the translation properties of the 1st bone. They're not the same name.

I tried to create 2 chains, and then set interaction setting to include FK, Rotation mode None, translation mode Absolute, translation alpha 1.0, but the translation still isn't copied exactly.

What am I missing? how can I do that?

[wicked forge]

I've received a bunch of motion capture animations from an OptiTrack system in the BVH file format, what's the best way to import them?

[ripe gazelle]

do you know where in Lyra?
Im not sure i know what an anim modifier is.

[grim star]

Look at this video: https://youtu.be/ha-4gt3iMUo?si=x7gEJ9hhnRsrwzrL. In order to extract speed, it's required to have root motion in your animations

[ripe gazelle]

surely you mean that for one method of extraction, a root motion is needed?

but i get it

one way of doing it is to pretend its a bicycle

[lime ore]

no easy way, just have to optimise it, its always easier doing things in engine unless you invest into something like better fbx for blender.

[prime tide]

thanks for the reply, already managed to learn all the basics of in-engine particle system and got the same result as in blender 😁

[honest bobcat]

How can I use ue5 retargeting mechanism to copy translation (exact copy) from 1 bone to another?

[ancient coyote]

HI Guys I'm facing a problem my metahuman is jumping and then starting animation how to resolve this?

[trail spade]

No one solved issues with weapon bone? 😦 Maybe I am overthinking it but running multithreaded animbp and socket desync make it a bit scary to fallback to sockets.

[zealous jewel]

I'm fooling around with various control rig stuff, trying to make some sort of snake like movement. I'm using various simulation nodes and things look ok, but it seems like the rotation of the bones is a bit messed up - the x axis of the bone doesn't match the direction towards the child at all. Is there some way I could simply orient all bones, so that their rotation matches the direction towards its child/parent (avg if both exist)?

Or do I have to make a spline IK for this?

[ember field]

Has anyone ran into an issue with auto-rig pro and mixamo animations where enabling rootmotion messes up the animation?

[slow brook]

Anyone know whats going on with my animation which is when the player warps into the locker they don't seem to turn 180 which the root does within the animation

The animation

Start and end transform points

The result

you can see they warp to the start and then to the end and you can see there is a turn in there but then things snap back to how they are

Am i meant to do a snap rotation or something to the player actor cause I thought thats kind of what the warp thing does

Now I do this mid way though the montage for the second bit of the warp so just wondering is this what could cause the issue ?

[polar kindle]

Cinematics can be done in various apps outside of Unreal and usually are. If you are looking for how you can do this strictly in Unreal, I would start with researching Visual Novel creators who have used Unreal. This would probably get you the information on how to do this in Unreal.

[slow brook]

So fixed my issue

[rustic swallow]

hi, I have a character which is skinned to the mannequin model, but because of its proportions, it is floating off the ground

how would I adjust it so that its feet are level with the root bone? do I do this inside the animBP, or per animation file?

[rustic swallow]

I think I need to run a postprocess animBP on this SkeletalMesh to adjust the root position? not sure if that is correct

[young barn]

I imported an animation into unreal engine (from blender) but the width is wrong. It is much thinner during the animation.

Other animations worked fine.

[silent ruin]

Animation scale issue often comes from incorrectly set ref pose's transform. Be sure they are at 1,1,1.

[silent ruin]

Take a look at these.

You will need to use Animation Scaled instead of animation or skeleton, and make sure your character is on the ground.

Or you can take a look at hte IKRig Retargeter workflow from Epic.

[young barn]

Where do i view this?

[silent ruin]

See Translation Retargeting in the screen shot. Those "Animation" and "Skeleton" has drop downs

[silent ruin]

Ahh darn I replied to the wrong question. You will want to verify the transform scale of your object, armature, and controls, and make sure they don't have funky parent setups.

One thing I saw often is that you have a mesh that is child of an armature, and when you make adjustments to mesh via scale, and didn't apply, it'd result in odd behavior with the result.

[young barn]

I think I found the issue. It's a bit hard to explain, but I'll try

Basically, for my first animation I didn't merge the objects while animating. After animating, I joined them all together. When I imported I got a bunch of broken animations, and one working as it should

For my second animation, it was already joined together

So now I'm only left with one broken animation

[young barn]

I don't have an armature in blender

[silent ruin]

er, how are you animating and exporting your animations.

You kind of need an armature/skeleton to store the final animation data.

[young barn]

Idk. I haven't done anything with the skeleton in blender. Unreal engine imported it as a skeletal mesh with a single bone

By the way, the name of the bone is something like cylinder002, but the 1 functional animation had cube001 in it

I can't really animate using that same part, it told me it's not compatible with the skeleton or something like that.

[winged violet]

Is there a way to set a CustomTimeDilation for animations similar to how it works with the variable of the same name on Actor?

Basically to be able to keep animations playing at normal speed while the owning character has a low CustomTimeDilation

I saved an animation from the sequencer as a linked animation sequence and when I tried to import it to loop the animation, it doesnt play in the sequencer. Anyone know why its doing that>

[pine remnant]

will AnimNotifies trigger when the anim montage play rate is -1 (reverse)? I want to make an attack animation in reverse whenever the attack hits an object but I don't want it to trigger the anim notifies associated with hitboxes.

I would rather not make separate, reversed montages that don't have animnotifies or modify the anim notify code but i might do that if there's no other option

[paper helm]

Hey everyone. First time posting in here.

Ive been seeing similar questions about this in forums but I havent found a solution yet.

Enabling root motion makes my character float.

A few things.

• I did not build the rig. It's the Akali rig from Agora Community.

• The root is at the pelvis, not the floor.

• Im an animator learning to implement animation into UE. Not a programmer.

My guess is there is something up with the root bone. Let's say i try to move the character with the root bone and in animation sequencer, the character will move in z space even if i only select the x or y axis by itself. This happens in local and world space.

Random question about UE Mannequins from programmer.

I was going through the mannequin assets and was curious what the deal is with in Rigs->Poses->Manny, there are so many Animation Sequences like "Manny_calf_l_anim" which just appears to be him standing there bending leg/knee to show movement. What exactly is the point in all these files? Is it just so we can see how the character looks when moving or are they used in another way?

[warm island]

can you do a 2 bone IK without an ABP? I have a simple skeletal mesh and I don't need complex animation logic, just IK

[wanton slate]

Thank you!

[wispy copper]

@dull bridge Sounds like they’re pose assets used to refine deformations around problem areas such as elbows/knees. The skeleton will probably have additional joints around these areas and will be animated in those files. Similar to how set driven keys work inside Maya. These pose assets can then be used in post process anim blueprints to drive these helper joints

Hey animators!

I am making an asset and have a question about skeletal mesh vs timeline animation on a static mesh

I am curious on the general performance differences between the two, my asset is pretty simple where I want 1 part that viabrates up an down and the other spins when interacted with (It's not a bop-it! I swear)

Currently I have this setup with a couple timelines that just update the relative location/rotation of the parts in question, but I am looking for resources on the performance nature of this choice vs skeletal mesh animations

[ripe yew]

How do I fix this fabrik issue? I'm trying grab on something.

[royal sorrel]

How's everyone doing Motion matching with melee sword animations?

Sword idles are generally where the character has their legs spread, but in motion matching example it does not

So it looks very weird when the character wields and hits with the sword (especially foot sliding when attack montage is played)

Any bright ideas?

[ripe gazelle]

Don't you overlay melee on a locomotion layer already?

Is there a good way to somehow rekey a walk cycle for a uniform speed? I'm looking at some zombie walk cycles that only make sense as root motions.

It kinda feels like I need to do manual plain old animation source authoring

[royal sorrel]

what do you mean by overlay?

do you mean layered blend per bone where the entire top half is controlled by it

or

do you mean dynamic additive layering?

[ripe gazelle]

Blend per bone but nevermind I think I misunderstood your question anyway

[wooden arch]

My imported pose from blender looks different. the first shows the broken pose, but the second shows what it should look like. What gives? The same thing happens in blender if I swap back and forth between actions

[royal sorrel]

@ripe gazelle see the problem with that. I go into the combat idle state (from idle) but see the feet, it plays the sword undraw (where the legs are spread) but legs immediately go back to being closed

[ripe gazelle]

Yeah I don't know, don't play the animation on feet 🙂

Like with layer blend per bone

[lapis rapids]

Hello

I have a skeletal mesh in unreal engine, that has double vertices (2 vertices at the exact same location). I don't want this, so I export it, import into blender, do "Merge By Distance", and then export from blender.

When I reimport the fixed mesh into blender, I can confirm that merge has worked, because there are no more double vertices. But when I import that same mesh into Unreal, double vertices appear again.
Tried tweaking all the relevant option in import dialog, like "Import Normals and Tangents", "Preserve Smoothing Groups".

Why is this happening and how to fix it?

[royal sorrel]

i can do an upper body slot only montage, but im telling you, the problem is, the anim set jujst looks way better with the lower body animation also playing, otherwise it odesn't fit

[ripe gazelle]

wdym? Just use the idle from the set when the character is armed.

[royal sorrel]

in the motion matching DB?

[ripe gazelle]

No clue what that is. It sounds to me like you don't have any full body idle/locomotion for unsheathed stance

can someone help me import animated mesh I created? It's a very simple window blind and I use no bones for it but in UE it does this

That's all I have

[astral pine]

So 5.5 came out and it is all great. One question, why Unreal Engine doesn't provide source code for MetaHuman Animator like MetaHumanSpeech2Face module?
Is UE becoming somewhat a closed-source engine?

Having closed source plugins means we cannot debug the logic to see what is going on internally (i.e. you are prototyping speech to face using audio in Chinese or Arabic)

[north nimbus]

Anybody knows why this happens? Weights? I am trying to replicate the control rig of IKs for ground steps using Mannyquinn example... it feels like only 1 side is not correct but when I compare it to the Quinn IKs my model moves also the standing leg like down to the ground but in the Quinns that leg just stands as if there were no step so thats not a normal behaviour... Thoughs 🙏?

[high dock]

uh if mesh is folding weirdly then yes weights

[north nimbus]

uhmmm so the reason its moving even the pelvis up are the weights? in Mannyquinns it doesn't affect pelvis at all, it keeps same position and the other leg is not moving at all also

[high dock]

what did you do to it

[shrewd sundial]

can someone help me with this, i watched some videos and looked online for a solution that works but nothing is fixing this

I'd say just make your root bone be at the floor. It's the standard way in Unreal as far as I know

Hi, I have an issue in the project, I'm using Lyra project and i had some changes in the animation BP and now, every time when I fire a weapon while walking my character scales down to 0 and then slowly coming back to scale of 1, I was looking into ABP but couldn't find anything. Does anyone might know what this issue might be?

Anyone know what happening here within my rig ?

I checked and the bones are orianted correctly yet when I raise the ctrl the bones have a odd twist in them

if I set the secondary axis they aligned better but the pad seems to be off

So odd one here, I've got the joint bit sorted however as you can see one landing gear raises fine but the other messes up after a certain value for some reason

both are using the same nodes obvs different bones

My inertialized state machine transitions are not blending at all. They seem to work just fine if I change it back to a standard blend. Are there any lyra type features I will be missing out on, if I remove the inertialization node from my anim graph?

Anyone able to help with this, when I put my control rig in the chain for my anim graph it fails and no animations coming through underneath will play

If i put it before the layered blend it seems only animation on the upper part of the body plays

[exotic cipher]

Did we get copy motion node with 5.5

[green walrus]

whats that?

[exotic cipher]

😒 its for layering. Watch gdc, they showed it there.

[wooden arch]

what is going on here? I'm trying to set an ik and the hands are stuck down there where the character root is :(

[silent ruin]

need to show the bottom half of your Details Panel.
Your Transform (Modify Bone) node right after the IK might also be overriding things.

[wooden arch]

second half

trasnform(modify) bone is the one doing it

just disconnected it and compiled

it goes back to normal

hmm

[silent ruin]

Transform (Modify) Bone is overriding the result of your Two Bone IK, is there a particular reason you are using it after Two Bone IK?

[inland creek]

I have a problem with my control rig when I try to bake it to an already existing animation. The joints find the correct position in the baked animation but whenever I toggle the "enable hands IK" It looks like it keeps the hand IK controllers where they should be but rotates all the other joints 90 degree. I attached the blueprints as well if someone wants to check it out.

[royal sorrel]

Is the new motion matching stuff like sprint, crouch etc only available on 5.5?

[slow brook]

Anyone know how to fix this, I want any anims I put within the sequencer to be the base and any control rig stuff to be applied ontop

[inland creek]

@slow brook You need to bake your control rig to the animation

[slow brook]

so in 5.4 I've found out they have an improved way of doing it with Layered Control Rig where you don't need to bake anything

[inland creek]

Interesting, did not know that

[slow brook]

yeah in 5.4 they added it

[noble pelican]

When I key euler transform controls they go halfway back to their previous transform for some reason? Doesn't happen with other types of controls (5.5)

[slow brook]

Anyone know why putting a default slot after a layered blend and before the output pose causes a exception and crash of the editor ?

I bassically need to in here somewhere inject what the sequencer is doing so it overrides stuff like the weapon equipped etc or better it be additive ontop

at the moment because of the layered blend the top half of the player character is not being inlcuded within the anims that the sequencer is player

[silent ruin]

I observed a behavior from previous work.
If you have a blend mask from a Skeleton active, and then copy it to be used for another skeleton.
The mask from the first skeleton will be displayed as None, yet still in use.
This will instantly crash your UE.

Might be what you are running into.

[slow brook]

is there a way to see if thats the case and if it is how to resolve it ?

[silent ruin]

manually review one by one, and set em to None

til it doesn't crash anymore.

[slow brook]

and what would I be setting to none specifcally ?

[remote phoenix]

Hey all, would love to hear your opinion on motion matching.
In our current project we are using the workflow shown in Lyra. Animation look good and we can easily extand them.

But I do get a feeling of fomo for not swtiching to motion matching.

In terms of usability and performance, is it good to switch to MM for mutliplayer game of 6 players? Will the engine handle motion matching for multiplayer?

Assuming that npcs will not use MM (for performance)

Thanks!

[slow brook]

@silent ruin So any idea what I need to do here ?

in terms of having it so the anim that sequencer players is not overriden but instead the contrig rig is layered on top

[silent ruin]

Blend Profile if you got states somewhere.
Blend Masks

if you have previously used blend mask in another ABP, then switched back to Branch Filter, the bad setting will still reside on the Blend Mask.

On the Layered blend.

As funky as it sounds, making a fresh node then re-create the filter settings might fix it.

[slow brook]

this layered blend node your refering to

Any ideas on this I can't work out why them two circle controls are up there when they should be much lower down

[slow brook]

so some how the forward is messing up and I can't work out why

[slow brook]

so another issue I have is when I do my sequence if the sequence isn't playing any thing animation wise the skeletal mesh returns to A Pose

[verbal grotto]

hHey guys, i wanna do a basic start animation for my car game

ive managed to do it via the sequencer, but how would I do inside my main blueprint?

[serene steppe]

Can you use a modular control rig in an animation blueprint?

I'm trying to use it to do final corrections to my aiming position after setting an Aim Offset, but it's just resetting the character to the default pose. Wondering if I'm doing something wrong, or if I need to use a standard control rig / IK.

Checking and unchecking the "transfer input pose" option doesn't seem to change anything.

Edit: This is in version 5.4

[mellow rivet]

Hello everyone
I exported my character geo, the joints, and ikHandles and I baked the animation on export
the animation does not play in unreal, and I get no errors except "could not find the bind pose. It will use time 0 as bind pose"
Does anyone have any ideas on what I should do?

[proven depot]

Hey guys, I'm having a weird issue with the left leg on my character when using the motion matching sample project and the UE4 manequin retargeter. For some reason, the right leg works fine, but the left is all wonky. Has anyone seen this before? I've been trying to fix it for a while now but haven't had much sucess so decided to ask here, thanks in advance for the help!

[quiet mist]

Trying to auto create IK on these FPS arms but it says it's missing a root bone. Googled around but cannot seem to figure out how to set it manually. Anyone know how?

No matter the solver I choose, the option to select a root bone is greyed out:

[inland creek]

@quiet mist You need to select the solver from the solver stack and then right click in the hierarchy window and select "Set Root Bone On Selected Solver"

[steep ember]

Hey everyone! First post here 😄
Im having some issues with my Physics Asset editor crashing when trying to preview animations or changing the pose. Both my own PA and the one that comes with crashes the engine (pasting crash message below, even if it doesnt really reveal too much).
I did see some mention of "cleaning the project", but Im not 100% on what this means exactly, so can anyone clarify this?
Any help would be appreciated! 😄

[thorn solar]

Cant seem to find much about it online so was wondering if anyone has experience with Montage Sections. Having an issue where im trying to loop the same section and it doesnt seem to allow it. Cause it seems to only play it once, which makes sense for how i think it works. So was wondering if they is a way to check when a certain section of a montage has finished playing so then i can then go to the next section

[wooden arch]

how do i solve the whole jiggling issue with ik?

the hand should ideally stay on the car wheel but it jiggers about depending on speed etc

Just wanting to know what settings I would look for, if anyone else has run into this issue

[mint river]

Have you considered using control rig instead and piping the ik position into it?

[mint river]

You would probably have more control over it using control rig

[wooden arch]

i want to learn more about ik

though

i mean, is there a control rig tutorial that deals with cars in gameplay?

[mint river]

control rig can be used in gameplay and isnt really limited to just working on animation. It would be using IK in control rig rather than that blueprint graph

Outside of that, it looks like there is some sort of interp happening with your ik targets. You have a set transform right after your ik solve, what does it look like if you just have the Ik solve?

[wooden arch]

still same issue

the transform set only allows the hand to follow the rotation of the wheel

[mint river]

How is the transform position set? trying rendering that transform and see if it jitters

[wooden arch]

try rendering only the transform?

[mint river]

yeah try to see if that translation position is the thing that is jittering or if its the actual ik solve

[mint river]

There should be a debug draw available in blueprint and you can pipe in the translation values

[wooden arch]

yeah it's the two bone ik causing the jitter for sure

removing it stops things, but then the hand stays in place

[sacred anchor]

Is there a way I can set the starting pose for my control rig?

[mint river]

hmm in that case im not super familiar with the two bone ik chains, i would just start displaying\rendering your inputs and joint positions as much as you can until something shows up as wrong...

[mint river]

In the construction event you can grab the joints initial position and use that to position your controls.

[midnight pumice]

How would you guys deal with body clipping on a first person camera

[solemn pilot]

I am currently trying to blend lower body and upper body animations using animations from GASP 5.5 and FPS Multiplayer Template 5, with the lower body having animations from GASP, and upper body having animations from the template, is there a way I can pull the current pose or animation from one animation blueprint to another? Both use the same skeleton so I'm not concerned about that. I just need a way to get the animation for the upper body, can anyone help me out?

[unique pike]

Random question but how can I create the project for the new 5.5 game animation sample? The launcher only shows the 5.4 version and using the fab plugin in UE 5.5 to view the asset it doesn't say add/create project. It just says view in vault or launcher which both do nothing to help, it just restarts the loop of add via launcher/fab plugin 😂

[silent ruin]

you'll need to setup collision checks, and tell the character to stand more upright when it would collide thru an object.

[next python]

if you want to see more info in here you might need debug symbols downloaded in the options for your engine version in the launcher

[solemn pilot]

Delete GASP from your library and reinstall it, it will update.

[unique pike]

that was it, thanks 😄

[flat current]

im trying to create a control rig, does anyone know why this is constantly jittering?

[quiet mist]

Would it be possible to animate my FPS arms inside of unreal instead of blender? Feels like the workflow would be so much easier

I would just use Blender to set up the models and rig them with IK. Then I want to create animations inside of UE5.

[scarlet moth]

Hey guys, I created this electrical window blind animation in Blender.
The default state is closed and I created animation montages to open and close it, works fine.
But now I want the blind to be open by default. How do I do this?
Can I specify somethiing like a default pose and use the last frame of the animation for it and apply it in the anim bp or sth like that?

[scarlet shard]

hey folks. any idea why is the weapon_r bone in the first skeleton displaying as the center of mass?

[eternal tendon]

Hey guys, has anyone noticed any changes in Motion Matching or Pose Search when updating from UE 5.4 to 5.5, and how to adapt to them?

I've built my animation system using Motion Matching (thanks to the Game Animation Sample Team). After updating from 5.4 to 5.5, the logic for querying from the Pose Search Database seems to be broken, and I'm curious if others are experiencing similar issues.

To give more context about my system: my game is top-down view. I control the camera's yaw with the PlayerController, and the character faces the mouse pointer direction. This means the PlayerController's rotation and the character's facing rotation aren't aligned, and the controller's rotation shouldn't affect the character's animation selection.

For the character settings:

• bUseControllerRotationYaw is set to true.
• bUseControllerRotationPitch and bUseControllerRotationRoll are set to false.
• In the Character Movement component, both bOrientRotationToMovement and bUseControllerDesiredRotation are set to false.
  This setup worked perfectly in 5.4, but after migrating to 5.5, I'm encountering some issues.

Currently, problems like incorrect animations being selected from the Pose Search Database during Turn In Place, or when aiming the character in a different direction while walking, are occurring. After spending two days debugging with the Rewinder and other methods, I've found that the root cause seems to be the PlayerController's rotation (which is the camera's facing direction in my system) affecting the Pose Search process.

Does anyone have suggestions on where I should look to resolve this issue?

left one is animation in UE 5.4, and right one is same project in UE 5.5.
Turn In Place doesn't work, and also when I move character left/rightward with pointing left,
in UE5.4, correct animation sequence (Walk forward/backward) is selected, but in UE5.4, incorrect animation (Walk leftward) is selected.

I would like to make my pose search system to be independent with player controller's rotation.

[eternal tendon]

Answering my own question:

It turns out the issue was caused by a slight change in the FPoseSearchTrajectoryData::UpdateData function in the PoseSearch plugin from UE 5.4 to 5.5.

// UE5.4
TrajectoryDataDerived.Facing = MeshComp->GetComponentRotation().Quaternion();

// UE5.5
if (TrajectoryDataDerived.bOrientRotationToMovement)
{
    TrajectoryDataDerived.Facing = MeshComp->GetComponentRotation().Quaternion();
}
else
{
    TrajectoryDataDerived.Facing = FQuat::MakeFromRotator(FRotator(0, TrajectoryDataState.DesiredControllerYawLastUpdate, 0)) * TrajectoryDataDerived.MeshCompRelativeRotation;
}

This is the code from UE 5.4 and 5.5, respectively.

In 5.4, regardless of whether bOrientRotationToMovement is true or false, the Desired Facing is set to the Character Mesh's facing direction.

However, in 5.5, while it's the same when bOrientRotationToMovement is true, when it's false, the Desired Facing is set by combining the Controller's Yaw rotation with the Character Mesh's relative rotation.

In my case, to implement the Character Movement I intended, bOrientRotationToMovement needs to be set to false. But since the Desired Facing in the Pose Search results should be the Character Mesh's facing direction, there was no issue in UE 5.4. However, in 5.5, the Controller's direction started affecting the Pose Search.

To solve this problem, one way is to modify the engine plugin code as shown above.

Alternatively, I can work around it by overriding Character->GetViewRotation() to produce the desired result.

Leaving this here in case others run into similar issues in the future.

[somber cosmos]

hey guys been following a bunch of guides but this keeps happening https://imgur.com/a/XsQQEnt

[worn osprey]

hi all, can anyone reccomend a comprehensive guide to retargeting and motion capture cleanup, or a guide to getting started working with rigs and animation in UE more generally? It's kind of overwhelming and hard to know where to begin

[scarlet moth]

Any ideas? 🙂

[silent ruin]

https://www.youtube.com/watch?v=N7WdyAeeDrw&t=537s

This would be a start.

Motion capture cleanup.... you could take advantage of ABP's layered blend per bone to mix in the motion data with partial blends.

And add a curve to drive the alpha of the layered blend.

[worn osprey]

Thank you @silent ruin !

[gleaming vale]

The new retargeting is almost like magic. It's crazy how great it works. That being said, are there any resources that you guys use to make sure that your skeletons are setup either to be most compatible with the retargeting system or to just have the same skeleton as the UE5 mannequin? I am having a hard time finding anything that works consistently for me.

[silent ruin]

Two scenarios:
Your character bone name, and hierachy, is 1:1 with epic's Manny(UE5). You should be able to playback the animation directly.
Your character bone name is not 1:1 with Manny. You should still be able to do it thru IKRetargeter.

As crazy as it sounds, the IK Retargeter is extremely robust, even allowing you to retarget human walk cycles onto quadpedal creatures.

like, you can really retarget anything to anything

[gleaming vale]

It is crazy. I just retargeted my whole animBP that way and for the most part it worked nicely. There were some weird things like the character is hovering higher than the source animations and one of the idle animations just did something wonky to the scale of the character.

[silent ruin]

you can config things pretty easily in the IKRetargeter so they stop hovering

I mean, that 3 legged alien's feet is planted XD

Hi, im hard stuck using the "Play slot animation as dynamic montage" node. No matter what i do it doesnt play the montage, i tried using play montage node it works fine but not with this one. Can anyone help me out here? Thanks!

i also tried without the prefix

[dapper anchor]

Is it viable in 5.5 to use Mixamo animations still? In the past I used an app called "Mixamo Converter" that worked alright but now the import interface has changed in Unreal and my animations are all screwy

[fringe oriole]

hey when creating a custom animation or character rig, is there a certain naming convention or criteria you need to follow so it doesnt come in all jumbled?

[dull bridge]

I am having some trouble matching my character movement with its animations so I just wanted to check here if anyone has any tips or something I may be missing. My character has a walk, jog, and a sprint with different accelerations and braking all that between them. Is all I can really do to the animations is slow/speed them up or down based on the speed/velocity of the character, or is there something else I am missing? I have been using root motion for pretty much all my human movement for so long I feel like I may have forgotten or missed something.

[silent ruin]

you can study stride warping, orientation warping in the lyra project.

[coral sequoia]

hi! why when using constrain.. the object what was constrained desapeard from render? i always need to bake it.
thanks

[silent jetty]

Is the animation sample project any good? In 5.5

I keep hearing it’s good but I’d have to build 5.5. I guess I could also just download retail

[sacred anchor]

Can someone help? My retargeted animation doesn't literally work

I love retargeting

Now I got it working but my character disappears in the retargeted animation

No wait the character is just REALLY small

Nvm it became 100x smaller just because apparently apply scaling is needed

Nope didn't work

[bold flame]

Hey guys. Just upgraded to UE 5.5, and our old workflow of importing animations seems to be broken - you get a different import window now, and the morph targets and the skeletal animation are now separate, instead of being combined into one. This is INCREDIBLY annoying, does anyone know of a way to switch it back to how it was?

[molten cedar]

Is there a good video or document of game animation workflows?

I want to try and create my own game assets using unreal's animation tools. I wanted to create core animations like a run, walk, jump, attacks etc. Then add on layers of fidelty to them, like start of the walk, end of the run, and more additive animations.

In the lastest 5.5 animation showcase,when he was going over animation layers,he showed a robot blending between different animations in a different scene/leveland I wondering if this was the professional or industry way of making game ready animation assests in unreal or was it just apart of showcase.

Hopefully my question is making sense and I would love to hear you insight.

[sacred anchor]

Can someone help? I exported my thing and I checked it has a scale of 1 but when I imported it into UE the scale is 100 and it looks correct but when I retarget an animation the scale goes to 1

[sacred anchor]

Do you want to create animations or get animations?

[molten cedar]

Create

[sacred anchor]

Blender

[molten cedar]

I see, is it more straight forward?

[sacred anchor]

Nope, making quality animations is hard

Not to mention getting characters and rigs

Personally I'm using mpfb2 to create the characters then I retarget animations to the character in UE

[bold flame]

I guess I am what you could call a professional! I still do all of my animations in Maya, but it is cool to see Unreal's in-engine animation tools become more and more advanced

I very frequently use animation layers myself

A key advantage to using external software like Maya or Blender is that you're gonna be able to find more pre-made rigs, and more external tools and plugins that'll make actually animating easier - also more support

Buuut, doing everything in-engine is a lot less hassle. Constantly having to import your animations into Unreal is a bit of a pain, and just being able to do it all right there sounds pretty appealing to me

[molten cedar]

Thank you so much for insight and knowledge.

The reason I wanted to try to make my own animation in unreal, because I saw how far the tools have advanced. But I wanted to keep it simple, making only a run or walk. But if I wanted to add variants for them, like a run with a lean or a walk settle.

Usually I can do in maya via layers and export the animation to the engine. In unreal, the workflow is slightly shifted I believe, that's why I wanted some professional insights of their unreal game animation workflows.

[bold flame]

Honestly, I'd be tempted to try the tools myself but I'm set in my ways omg

[molten cedar]

Completely understand lol

[bold flame]

I figure it'd totally be worth a shot, though! Might as well give it a try

I'd wanna do an awful lot more experimenting with new tools and workflows, but yeah, in a commercial environment, sticking with something you know to work is hard to avoid

At this point though I doubt you're gonna find a single studio who's already using it, 'cuz it's so recent

[tranquil cape]

What's this?

[naive zodiac]

We're using a Random Sequence Player node to switch between various idle animations. We want to use the same animation statemachine for different characters that each have a different set of animations. So we were looking for how to turn animations in Random Sequence Player into pins so the input animations can be selected based on which character it is. It doesn't seem like this is possible? How can we achieve this?

[silent ruin]

you can take a look at Lyra's idle break chooser for randomlly play idle break animations. They are taking advantage of where the player is in world position to randomly (Yet consisntly based on location) choose when and which the idle break is played.

[hazy granite]

Hello! I've been messing around with a local multiplayer first person shooter project, and I've been looking to make some animations for the player character. Now I'm no animator, but I'm realizing that whatever first person animations I make have to look good in third person as well and line up so that there's no miss-match between first person view and third person view. I'd like to use stock locomotion animations so I don't have to animate the entire body, but I would like to have my own animations for whatever guns I want. I'm not sure how to approach this, should I make upper and lower animations separately and blend them in the AnimBP? Do I just buckle down and make full body animations? Haven't found a whole lot of resources online covering this topic, and there's quite a few different ways I could approach this, and I don't want to waste a bunch of time on something that won't work. Thanks!

[naive zodiac]

Thanks! Is that still alternating between idles over times? We specifically want the behaviour where we have a bunch of idles and they'll alternate randomly when standing still, so it's not the same thing all the time.

[silent ruin]

yeah, think idle as a short 30-60 frame loop. And idle breaks as, well, idle breaks, that plays unique bits to mix things up as needed.

[naive zodiac]

Okay cool, we'll check it!

[tranquil lark]

Super necro, but this might help with my longtime animation woes of getting hands to sit correctly in a variety of guns.

I have always put a socket on the hand itself in UE. From what I'm reading here, the right way is to have it on the ik_hand_gun. So, in the DCC, the weapon would be a child of the hand. But then the ik_gun_hand constraint is the gun and the respective hands are the respective ik_hand stuff.

[nimble torrent]

Yep! That's the way to do it!

[tranquil lark]

Genuinely curious though - why is this the preferred way instead of doing it with the hand? So the gun being constrained to the hand.

[nimble torrent]

The advantage is that you can play animations on the characters arms relative to the gun.

So if you procedurally move the gun, and move the ik_hand_gun bone along with it, and then attach the arms to the ik_hand_left and right bones respectively, you can keep playing the animation, but move the gun around.

This lets you do things like procedural sway, aiming arcs, etc, much easier.

[tranquil lark]

My big problem has just been getting two guns of the same type to be held correctly 😅

Much lesss the sway stuff

So like a 1911 and a glock

[tranquil lark]

How would you go about handling these different guns like I said? Like, a 1911 has a more thin handle than a glock. So adjusting for that, along with the finger position. Or is this just one of those - bite the bullet and either accept some flaw or animate with each weapon directly?

[nimble torrent]

You can do a separate hand pose for the gun, and then layer that over top of shared arm movements.

But a lot of the time, you do end up having to do some custom work per weapon, no matter how superficially similar they are.

[tranquil lark]

Is that what the anim poses are used for?

I haven't ever been able to figure out that

[nimble torrent]

It can be, you could use a pose library for that, or you could use a single frame animation.

One of the unfortunate things about game development is that there are few correct answers, but there are many incorrect answers.

[tranquil lark]

Okay. So have the basic animation, then each gun would have an additive animation that is their actual position.

[tranquil lark]

Yeah, I'm a programmer, not an animator. I can do stupid basic monke stuff in animation. I probably animate like it is 1995 🤣

[nimble torrent]

You'll figure it out!

[bold flame]

God, I'm not gonna lie, the updates to the animation sequencer are horrible in 5.5

Why do I have to manually merge my morph targets with my base animation now? 😭 Also, constant name conflicts with imported animations that didn't exist in 5.4.4, tons of extra steps that really slow my workflow down

[coarse thunder]

What donyou guys usueally do when it comes to animation? Is it common to animate in blender and export to unreal or export a rigged mesh and animate in unreal if possible? Whats the best workflow?

[bold flame]

We do all of our animation and rigging in Maya! Then, we import the rig into Unreal, and export all the animations and link them to the rig in UE, on a per-shot basis

(Maya is essentially the same thing as Blender fwiw)

Is that the most efficient workflow? Perhaps not

[inland creek]

Why does not my IK hands completely rotate when I rotate the root?🤔

[chilly laurel]

Hello guys, GASP question.

Is just me or disabling the want to strafe to make a forward facing locomotion and building in Shipping makes the character turn looks very bad compared to Editor / Development?

[light plover]

I feel like I'm missing something. I dont understand how this anim state graph transition is firing in the animation preview. Preview uses class defaults, no? Unless that's wrong, only one condition is met and yet its continually going through this transition...

[light plover]

I'm beginning to think something is wrong with the isMoving bool. I changed the above to be calculated outside of the anim graph (condensed to an isWalking bool so the transition can use the fast path) and that transition fires correctly now. But alas, a new problem! Transitioning from walking to idle when isMoving != true does not work...

Okay yeah wtf. Just made a new isIdle bool for the hell of it and the transitions dont ignore that. whyyyyyyy 🤯

[brisk ridge]

I'm looking for a little advice about morph animation. Until now, for games, I've always simply rigged an animated a character using bones only. I recently purchased 'iclone' which seems to be built around using morph targets for facial animation. It uses a plugin for unreal which is great. However I've never used morph targets in unreal. Does it work well in unreal? is this common practice? or should I for iclone to just go with my traditional approach? I presume i just import the animation with the morph animation included in the fbx and it should work automatically? or is there extra steps to make it work?

[warm island]

in ABP graph, is there a way to wait for an animation loop to finish before transitioning onto the next state?

[warm island]

morphs are fully supported and work well. it used to be the defacto working method for facial animations other than bones

[brisk ridge]

@warm islandUsed to be?

[warm island]

with meta humans they may be using something else

I dunno I never worked on them

but with Vroids for instance, it's all morph driven

[brisk ridge]

@warm islandAhh I see. Thanks. I'll try with morph targets then.

@warm island what is vroids by the way?

[warm island]

it's a premade anime character creator, you can use it to make a base, make a character or a chibi

it's free to use

[brisk ridge]

ah i see, thanks.

[halcyon basalt]

When working on an anim BP, is anyone aware of the optimal way to combine an 8 way directional blendspace with an upper body slot for idles/movements based on an enum like equipped weapon types?

[brisk ridge]

Another question. I'm currently converting a game project from unity to unreal. In unity we had all the non player characters using root motion to navigate. From learning unreal it seems that it is more common not to use root motion to navigate and have the character driven by the blueprint character velocity. I actually like the root motion method though, and I would prefer to have the velocity driven by the animation play speed root motion instead, is this possible?

[azure roost]

SHEEESH.

I´ve been trying to figure out a better way to animate ANY morph target on ANY skeletal mesh without having to create a specific blueprint animation for each and everyone and NOBODY offered the simplest solution out there with zero need to make any custom thing...

Add the built in FK control rig, set it to layered, select the morph target name, animate, done...

[warm island]

@brisk ridge iirc you can use root motion but as I tried it in both unity and unreal, root motion isn't that good and causes tons of bugs.
The animations have to have root motion enabled and dialed into the frames, enable the boolean and I believe when you play the animation it should work

@azure roost never heard of that, can you share your results? I was in the process of making a custom logic for it.

[azure roost]

Right click on your skeletal mesh component, add control rig, select "FK control rig", set it to layered. Then you have all curves on your existing mesh, including all morph targets available and can animate them.

[warm island]

Ohhh and you do it through sequencer!

[azure roost]

Trick is to set it to "layered", so it doesn´t override your existing animation assets etc.

[warm island]

I have put sequencer on the backbones for a while now but maybe that is way easier than what I was doing... thx!

Backburner **

[azure roost]

I´m probably gonna end up adding a custom control rig, that ONLY collects morph target curves and maybe filters them by the currently used mesh. Because rn the prebuilt fk control rig displays ALL curves including all morph targets on all skeletal meshes referencing the same skeleton.

[azure roost]

Oh, we´re only doing linear content (cinematics), so its literally our main tool...:)

[warm island]

Oof so if you have many, it's a pain...

[azure roost]

I wouldb´t do it this way for games.

[warm island]

Ah I'm doing some scenes but they are interactive

[azure roost]

Yeah, you can still filter wich curves to use using the FK control rig, I just want some automatic filters...:)

[warm island]

Thanks for that. Looks like I was on the right path then.
Working with 40 morphs ain't easy....

[azure roost]

Jup.
We need an Unreal trained GPT urgently...All that information is out there SOMEWHERE, but its really hard to find info on stuff thats a bit more in depth and "out of the box". 99 of 100 videos on how to do the same thing thats covered well in the manual anyways and the one showing how to do what you need is buried in a 2 hour talk of an unreal fest presentation from 3 years ago...:)

Been trying to find a way to use "lead pose component" in a project with raytracing enabled WITHOUT crashing for months now and I can´t believe only a handful of people have had the same issue and literally nobody has been able to even point me in the right direction...
And seeing how lead pose component is used in the official metahuman blueprint it seems like its either
A) A massive oversight from epic...
B) A very project or hardware depending issue...

I´m often wondering if 99% of people just give up and move on when encountering a problem like that, instead of keeping at it like a maniac as I do...

Hi everyone, are there any workaround for animating xgen hair from maya and then imported to unreal engine?

[woven hemlock]

Has anyone ever run into an issue where the viewport correctly renders match previous bone, but not on MRQ?

[sacred anchor]

Can someone help me fix my animations?

[pseudo yarrow]

Hey guys, I'm looking to create a true first-person character using a single skeletal mesh and I'm drawing my inspiration for how I want the end result to look from this video here:

https://www.youtube.com/watch?v=6KDGIEODDAU

Before looking into this I made my own "true" first person character using two skeletal meshes:

https://youtu.be/MHbRrJmqqwg

One mesh was for the body and the other for the arms. The way I did it before isn't bad, but I think it would be nice to have the option to 'free look' and see the shoulders of the character in first person and since I'm using motion matching it would be nice to have the weapon animations blend into the unequipped idle animations when the weapon is put away.

Any thoughts on the matter would be greatly appreciated.

[warm island]

are there any good practices when setting up the joint vector?

shouldn't it be a bone?

[wraith swallow]

I have a hip holster on my playable character that has some shape keys/morph targets on it. That hip holster is a child of the main character mesh. How do I use the locomotion animations to drive the shape keys of a child mesh? I added a curve to the locomotion anims, but it only works if I play the anims directly on the holster mesh. But obviously they're being played on the character mesh.

Essentially I want an animation curve from an animation playing on the ThirdPersonCharacter's Mesh to effect a child skeletal mesh

[small bramble]

im using a custom solution for car physics and i tried to animate wheels on a skeletal mesh through transform (modify) bone node but it doesnt work for some reason. the variable is updating. what am i doing wrong?

[small bramble]

nvm i changed translation mode to add to existing and now it works

[rotund crown]

is control rig the best way to aim an animation according to the aimoffset and crosshair? i tried coding bone rotations in when an animation montage plays over the state machine (walk, idle, run) and kind of realized how broken it is, for exammple if a player is punching, my guess is that maybe your supposed to use some IK solvers and force it to be in the Location of the vector location of the Impact point for the crosshair. any advice for a noob thats trying to blend like 3 animations at once?

[royal sorrel]

Can someone who is smart with animation tell me why this is happening?

I have a simple block blendspace 1d, why is the turning so janky?

[naive mountain]

Character controller rotation speed.

[royal sorrel]

Which one here? @naive mountain

is it rotation rate Z?

[royal sorrel]

I changed the rotation Z and it didnt work

[royal sorrel]

If this provides more info, I'm using motion matching. Not sure if something is being overriden. But I do transition into a blend space for this block state

Plaese let me know what else can be done

[rigid gate]

guys anybody knows about add bones or ig character on unreal engine control rig have squash and strech animation

[naive mountain]

Oh with motion matching you have less freedom. Rotation speed of 150 or lower not help?

[royal sorrel]

fixed it @naive mountain , seems like epic is setting rotation to 0,0,-1.0 in the motion matching example on tick lol, not sure why

why do you thinik theyre setting rotation value to this on tick?> what could be thje reason

[serene arch]

when doing true FPS with a single skeletal mesh, is IK required to keep a hand from looking desynced from the weapon? it can't be done with aim offset alone right?

IK seems overkill but i can't get it to match up no matter how i animate it

[naive mountain]

Probably due to the way motion matching is set up or something. I would probably double check to make sure he didn't break anything. Try all the different animations in the set. Hopefully, it just works that easily.

[silent ruin]

great work dude.
You should be able to use setup that you are already using for root yaw offset to enable a degree of free look, basically you are altering the yaw accumulation behavior upon holding the free look button.
If you need to blend into the unequip idle/out of, you will need some kind of full body anim that enables that transitoin so it is not just a smooth blend.

[distant ore]

I imported a skeletal mesh into Unreal 5.4 but the mirrored bones don't work with my animation. It also added "(Mirrored)" after the naming of each bone that has been mirrored in the 3d software. Is there a way to fix this? I heard it's because of the name inside the parenthesis that the mirrored bones don't work.

[scarlet moth]

Is there any way to pause a playing montage and resume it AND also pause and resume the audio that it plays?
I can pause the montage, but the audio continues and then it's out of sync.

[bold flame]

Anyone know how to get this import menu back, in UE 5.5?

[scarlet moth]

What do you mean with 'back'? It's there for me, although a bit different with more options.

[bold flame]

Yeah, that's just it - we used to import our animations via this window, we could just check off "Import Mesh", and the animation would be imported in one go with the correct naming conventions and morph targets baked in

Now it imports the bone animation and the morph targets separately, and nukes any naming conventions, making the whole process take a LOT longer

[scarlet moth]

Ah ok, I can't help with that, sorry 🙂

[misty dagger]

Hello everyone. Im asking for advice on how to do this on the best way.

I am making a turn based RPG and this is the battle state on the animation blueprint. Here is a bunch of animations that the characters can do while on battle.
Which would be the best way to wire this and allowing that most of them can be interrupted by hurt animations

[uncut musk]

Hello, don't really know where to post this, I have issues with skinning in blender, does anyone can help me with this ? you can mp, thanks 😄

[loud field]

Hey all, I'm trying out the new quadruped modular control rig modules in 5.5, but for the life of me I cannot get the animal spine module to spawn a tail socket. I looked at the module and it looks like all it's doing is finding the children of the pelvis and spawning the socket based on the name. I set up my skeleton in the same way the SK-Dragon template is set up, with the tail chain being a child of the pelvis and named tail_01, tail_02, etc. , but nothing I try seems to make the module recognize that there should be a tail slot. Has anyone else encountered this/know what might be going on here? The rest of the modules work as expected.

[tight basin]

This is a very big question with no right answer. A 'common' and beginner-friendly way is to play all 'event-based' animations via Animation Montages. You can assign different slots if you want to do layered blending or logic to check how the montage should play

I am trying to change the skeleton of a Skeletal Mesh asset that is only using one bone ('head'). There are some extra bones on the source skeleton which aren't used.

Is there a simple in-engine way to get this working?

[misty dagger]

Ah. Too late, I already did this...

But I dont know, having all these booleans for these events doesnt feel right

is there a better way?

Dont laugh >~< I dont know any better

[bold flame]

LMAOOO

Jkjk :3 This already looks way over my head, good luck with it...!

[misty dagger]

https://cdn.discordapp.com/emojis/913286151404654623.gif?size=48

[tight basin]

I would suggest reading up on 'state management'. There are lots of different ways to approach this, there is no 'simple, correct answer'

[misty dagger]

I know, im just expressing that feels wrong having this much bool variables

[tight basin]

I would recommend treating animation as a 'visual representation' only of what is happening in your game code elsewhere, and to set up a 'neat' system to relay information to the AnimBP

And no, 50 bools is not neat x)

[tight basin]

As I recommended, the most simple thing you can do is just to have an AnimMontage slot in your ANimGraph and just to tell the game code to play an AnimMontage when certain things happen

Leave the state machine for basic locomotion (e.g. a blendspace from local velocity)(

[silent ruin]

yeah your setup is better off using Montage Play, with rules on which attack can be used configured via GAS.

[tepid ruin]

guys, can this thing actually transition to KnockedDown if Sitting transition wants isSitting variable to be true and KnockedDown transitions wants isKnockedDown variable to be true. I set them both to true, but machine gets stuck in Sitting state :/

[silent ruin]

you can add some AND checks

Or some NOT checks

Like KnockedDown should Exist When NOT Knocked Down

and Sitting should exit when NOT sitting

[misty dagger]

How should I handle the looping emotions such as sleep start, sleep loop, sleep end with the thing you suggested?

[silent ruin]

and allow a transition from idle to Knocked Down

[tepid ruin]

I wonder why it doesn't transition from sitting to knockeddown :/

[silent ruin]

what is the rule inside the highlighted transition

[tepid ruin]

because I need to have different knocked down animations (well, it's basicallly unconsious state) for sitting, standing and laying down positions

it's as simple as that

I don't want to have mixed SittingUnconsious state if I can avoid it

[silent ruin]

Yeah, you could just have the state that gets managed by the enums to select sequence to set on tick.

It'll check to see if the sequence needs to be changed

and swap em out as fit.

[tepid ruin]

hmm, damn, not sure if I get what you mean 😦

[silent ruin]

Let's take a step back. What are in these two

[tepid ruin]

first one is CharacterPosition != Sitting and second one is CharacterMindState != Unconsious

[silent ruin]

It might be undecisive beteen going back to Idle verssu Knocked Down.

You may find success by adjusting the transitions' priority

so KnockedDown has a higher piority.

[tepid ruin]

how do I do that?

ah, I see, some Priority Order

nope, didn't help

like I set CharacterPosition priorities to 2, and kept KnockedDowns to 1, right?

[silent ruin]

yes

[tepid ruin]

didn't help, I wonder it doesn't even consider to check CharacterMindState :/

[silent ruin]

maybe this then

so when its not sitting, it goes back to the conduit to find the next proper state

[tepid ruin]

yea, but the thing is it must be sitting.. xD it's kind of sitting unconsious

i think i will just have to create regular spider. like sitting is (sitting && !unconsious) and sitting unconsious is (sitting && unconsious)

[silent ruin]

If your enums are not updating properly, that'd be an entirely different problem.

you said both can be true?

[tepid ruin]

nono, I checked that

yea, they are both true

[silent ruin]

how, b/c aren't they enums, or am I crazy

oh dear, two different enums

[tepid ruin]

it's two different enums. one is mind state another is character position

[silent ruin]

I thought its the same enum this entire time...
yeah you need to set it up, so one of them has priority.
Like if Sitting & Knocked Down, use Knowcked down.

[silent ruin]

basically waht you said here.

[tepid ruin]

oh okay okay

[silent ruin]

you can setup a enum driven Start,Loop,End.
With On-Update converted sequence players.

Take a look at Lyra's Cycle State in their ABP.

They are using directional enums to drive their walk cycles, simlar concept can be applied for start cycle stop of sleep, eating rest, stun.

The setup can still be montage driven, where on end of loop, unless timer is up, keep repeating hte same montage.

[tepid ruin]

btw, I do it by changing the state for ABP while playing montage for state changing. is this the way? it looks more or less okay :/

Like going from standing to resting. Play standing to rest montage set state for machine to resting.

[silent ruin]

for that kind of setup.... I recommend a inbetween state with automatic transition.

It'll basically play it out, and automatically transition at teh end of the sequence.

[tepid ruin]

I do it by activating GameplayAbility. It needs to check some other stuff as well, like can character rest or not. Does it change anything?

[silent ruin]

you just check and see if the enum is allowed to change

and when its allowed, things should kick in the lock the character in place

and the animation playing to transition

[tepid ruin]

Kli you were right. I had child ABP which I forgot to bind enum value to 😢 And I was checking value inside the parent animation instance class. Now it works fine like this

No spider needed xD

[silent ruin]

Another day being a programmer's rubber duck.🫡

[tepid ruin]

Kli, I'm sorry to bug you, but maybe I can ask you one more question regarding strange mesh rotations during my animations? 🙂

[silent ruin]

lol sure, send it

[tepid ruin]

well, here you go. I'm not sure if it possible to make anything out of it. But for some reason it's being very glitchy. Instead of just playing the animation without doing anything to mesh it rotates it here and there 🙂

I don't see thing happen in animation sequence

[silent ruin]

can you do the same thing, but print string for the actor rotation

[steep rain]

Sorry if this is a more a Blender oriented question but does anyone know why a simple fbx file with an idle (pose) animation is uploading 286 separate animations?

[tepid ruin]

it's not being changed

[silent ruin]

your sitting animation is facing -Y maybe

[silent ruin]

https://www.youtube.com/watch?v=pPL8r1Q7EZo

maybe try this

[tepid ruin]

oh wow

for real

[silent ruin]

🤣

[tepid ruin]

damn

I can fix it with keyframes in animation, right?

[silent ruin]

your mesh follow UE naming convention like manny's?

hierachy too*

[tepid ruin]

I guess

[silent ruin]

oh UE4 manny.

So let's try the simple way. Bake animation to FK rig, adjust the pelvis position/rotation, or just the root rotation, and see if it'll fix it.

Be sure to save the level sequence to see the change reflected in your animation sequence.

[tepid ruin]

damn it, I'm tyring to change the rotation, but when it breaks the animation. I mean it begin to rotate in different dimensions as well :/

[silent ruin]

does root only works?

[steep rain]

Thank you! Turns out all I had to do was uncheck the all actions option in the blender exporter

[tepid ruin]

Like I'm trying to do some stuff, but it doesn't do much xD

I'm super bad at animations

[silent ruin]

try this https://www.youtube.com/watch?v=PoPFKqtrvQ4

[tepid ruin]

but basically the problem is in my animation, right? somebody decided to make it facing different direction for unknown reason?

[silent ruin]

yep

[spare kiln]

hey guys, I know this might be a very subjective question, but what about AI vs Player animations.
I wonder how much a player will notice or how much it would impact the "feeling" of a player, if e.g. player sword animations are the same as for AI and how common or uncommon doing this is.

[silent ruin]

It all really depends on what the attacks are.
There are plenty of "attacks" in Elden Ring that are repeats of what enemies uses, which pretty much the exact same timing.

Yet I don't think anyone complained about it.

[rigid geyser]

anyone has tutorial for this node? I couldn't get my IK leg to work

[silent ruin]

you'll need to add a leg definition, then tell it which bone is the IK bone (The IK bone is used to represent the foot position and location in 3D space)
FK Foot bone is going to get attached to the IK bone. You tell it how many limbs are in the chain, and it'll do its best to IK move to the IK bone's transform.
It is very important for you to define the foot bone forward axis, you can see it if you use the location gimbal in local space.
You can even define hinge rotation axis so the bones in the middle can only move in 1 axis (Think knee, or the reverse joint of a zealot from starcraft 2).

[rigid geyser]

i tried that but couldn't get it to work

but if i remove that then the legs are fine

im probably missing something

[silent ruin]

your forward axis

and hinge rotation setting

[rigid geyser]

changed them didn't work

[native mica]

Could someone help me make the fall of the camera look more natural? At the end of the sequence the camera just stops abruptly and I don't know how to make that look more realistic and smooth

[frank parrot]

hi! anyone knows how can i clamp the rotations of a bone on the animation blueprint

i want rotations to not fully play

[gleaming vale]

Hey all. I'm trying to import a skeletal mesh with some animations from blender and its giving me this error:

I didn't make the rig but is there something I can do to eleminate extra root bones?

Is it just a matter of parenting bones?

[silent ruin]

My guess is you are using blender.
UE FBX importer checks for the name "Armature", and skips it, then searches for the next bone in the hierachy.
In many Blender based rigs, multiple bones can exist at the "root" after Armature.
Your best chance is configure your export so they only include deform bones, and mark the bones properly for deformation, then export.

[gleaming vale]

I do have it marked to only include deform bones. This isn't an armature though. It's a mechanical animation so it's just a bunch of individually created bones. I noticed that a few of them don't have parents which I think means that UE will read that as a root. I reparented them and I'm not in the process of realigning them for the animation to see if that works.

[silent ruin]

Yeah that's a issue. In this case, you need to properly configure yoru bone hierachy, so they all sit under a "root" bone.

[gleaming vale]

I thought as much but thank you.

[silent ruin]

you should be able to just add a parent to all of them

[gleaming vale]

Yeah that totally worked. Just imported it with no issues.

[silent ruin]

and all your animation should still be a-okay

[gleaming vale]

You would think so but unfortunately not all the bones were in a "chain" so when I parented them, they moved out of place. It's all good though. I zeroed out the transforms and gave them so appropriate keyframes and got it lookign the way I wanted.

[silent ruin]

hummm, it shouldn't happen, if you don't check the connected box

[gleaming vale]

Either way, it's fixed now. Much apprecaited.

[silent ruin]

Glad to help

[honest bobcat]

Animation blueprint: how can I blend motion matching only if it found something?

[small bramble]

Does anybody know why a casted vector array outputs only 1 element instead of 4 in animbp?

[silent ruin]

right click and break the vector, or just drag it out then break the vector

[small bramble]

i cant break the array

[silent ruin]

you get an item from the array, then break it

[small bramble]

oh right

this print gives me only one element instead on four

in bp it gives all four of them

[honest bobcat]

Perhaps generally then? how can I always run a node, and then blend it by bool?
When the bool is false, the node won't run anymore :\

[small bramble]

am i missing something? all element are the same in animbp but they are working fine in car's bp

red is cars bp and yellow is animbp

maybe its because im setting the array through make array? but why does it work in bp but not in animbp then

[honest bobcat]

anyone? 🥺

[mellow pebble]

Has anyone noticed that Force Front XAxis on skeletal meshes has disappeared in 5.5? Kinda destroyed my pipeline 😦 Is it a bug or?

[gleaming vale]

Potentially stupid question here... can I import static meshes with animations?

I'm trying to build a space station that is kinda messed up, has debris floating and a broken off part that will be slowly rotating. Do I need to create bones for each of these elements in Blender and then import it as a skeletal mesh or can I just animate the meshes and import it that way?

[silent ruin]

my trick was to layer blend a useless bone in.

[worn marlin]

hope control rig in 5.6 can have events for triggering anim notifies

[silent ruin]

for slowly repeating rotations, you amy find success using a post process ABP and have it slowly rotate taht way.

you can even use threadsafe update to tick the rotation change

[ashen junco]

You could either bake a vertex animation, use some World Position Offset Math, or animate it in Niagara

[silent ruin]

yep particle driven solution would be lighter

if its just static floaty no gameplay

[gleaming vale]

This is what I ended up doing because this is just for my title screen

It's a prop that sits in the background behind my title menu widget

[ashen junco]

Yeah, then simpler WPO math would do the job (or vertex animation texture if the animation end up more complicated)

[gleaming vale]

Agreed. I was overcomplicating it, trying to export a whole animated scene as an object when really I only have one large rotating element (the broken off part of the space station) and all the debris I can do via Niagara)

[tough olive]

How can i animate those cables for game

[misty dagger]

Does anyone know why my run animation is looping once before coming to a stop? Is there any way to get it to stop immediately when it changes state?

[silent ruin]

make transition like 0.01 second.
And tick your looping checkbox on the sequence player

[wide idol]

Is there a way to make child blueprints from animation blueprints, but having different skeletons?
I find it difficult to believe that I had to create multiple blueprints and copy this simple code in each individual blueprint.

[misty dagger]

It's still definitely looping but hopefully it will be imperceptible to the player. Thanks for the advice 🙂

[honest bobcat]

where are these defined / how do I define more?

[ivory osprey]

Try right clicking the asset, there should be an “assign skeleton” option or something 🤔 If you don’t see the one you want, you can do two things.

Add that differing skeleton to the “Compatible Skeletons” list found in the original skeleton asset (this is a separate window I think).

OR tick “Allow Incompatible Skeletons” in the search filter. In principle, a Compatible Skeleton is a VERY similar asset/joint hierarchy with differing leaf joints.

Not at my comp atm so I can’t check this 100% but I THINK this is how to do that. Bc I’ve had plenty of child animBPs with way different joints/skeletons. It’s possible!

Also…you might want to put that logic into the ThreadSafe function for a small perf boost

[runic canyon]

is it possible to change transform of a skeletal mesh bone in regular blueprint?

[vernal rain]

Is there a way to make root motion not rotate the actor? I have a roll animation but it ends up janky as a result of rotating the actor since the root bone rotates in the roll... for my case it'd probably work much better if it didn't.

If not I'll probably just not use root motion for this and move it manually, but figure I'd ask :)

[ivory osprey]

Umm you could make a control rig that locks the rotation maybe.. not sure if thats the best way haha. I solve too many animation problems w control rigs

Could also check for additional root motion settings on the anim sequence 🤔

[vernal rain]

At least none of the settings I found seemed to affect it, but I'll see if doing anything with the control rig would help, thanks

[formal whale]

Hello everyone, I have made a blend space for the shots taken by the Enemy character, and it works. Now I would like to do the same thing with the death animation; however, the blending is not well done. For example hitting the enemy at an angle of 0° between shooter-Character and enemy works, if shooter-Character hits it at an angle of 45° it works, while for intermediate angles (ex. from 45° to 90°) the blending is poorly blended.
Is the blending space wrong or do I need to add more animations to blend them well. Sorry for English.

[cobalt skiff]

Hi I am making control right now that will enable me to make variations in the y offset for B. I was B to still maintain the rotation of A but I am getting is some sliding in the x-y plane when B copies the rotation of A. I am using a parent constraint node to parent the transform of B to A. How do I avoid lateral motion of B while maintaining vertical motion and rotation in the z axis?

As far as I can tell animation montage blend out property is blending out the animation BEFORE it ends.
e.g. "0.25" will take 0.25s before it's done, and blend it out. Right?

Is there a way to blend out AFTER the animation ends? sort of keep it idles/same last pose, and then blend it out for 0.25s

[small bramble]

why does my bones resize when i use rigid body node?

[rotund crown]

check it out, i was able to aim offset, with a state machine running the animations, with a montage playing and offsetting with control rig, theres a small bit of jank, but i got the player to be able to aim at the center of the crosshair properly, kind of nice when u can blend like 3 things at once

I'm not an artist, I was just wondering about cartoon scaling. Most of the time my models are all scaled accurately (i.e. character at 1.77m) but then I was wondering what the general practice was with more cartoon characters. My character is a little cartoon cute guy and here he is 1.4m but the original version was 0.48m. I'm just kinda curious if there is a general best practice for the sizing or if I should just make a general note of his height.

[ivory osprey]

This could be an old but prevalent issue with rigid body nodes. Pretty sure if you’re scaling a mesh dynamically, it only takes in the original scale and alters the bodies according to that. There really should be a scale input for the RBAN node to avoid this frustration.. 😩

https://forums.unrealengine.com/t/rigidbody-world-space-simulation-overwrites-scaling/674660/11

This thread has multiple ways to fix the issue. Virtual bone + copy Bone nodes work very nicely, but ofc its tedious, as you need to basically add a VB for each simulated “chain”.

Hey everyone!
I'm really fascinating with Lockdown Protocol animations.
I thought maybe someone here have a good idea how can such animations be achieved.
My first thoughts was full body IK but I'm not sure..
What do you think guys?
Uploaded a small video for you to check out some animation
https://youtu.be/cE1sCgaywGg

[green skiff]

slower spin will become slower or faster. Sometimes, object will regulate their rotation when falling.
bounce on impact. Objects always bounce or break when they impact the floor.

idk I'm not a professional

Hey guys here is the thing. I spend 2 years, trying to get my character / The base mannequin. To walk i all 8 directions, with smooth walk and transitions. But it alway end up been flooding, crunky and flickering movement. And I justed all the turtles i can find out there, same result, or they are lucked to only this 1 tutorial, and I am unable to adapt the system, with other animations. I am kinda stating to get a little frustrated here, any help in here?

[spare kiln]

but are they using motion matching?

[frozen breach]

I've been looking on ways to sync animations from 2 different skeletal meshes each with its own ABP (mount/rider situation).
I copied and pasted the same event graph logic, all 1D/2D animation blends have same values, animation sequences have same length, but I'm still getting desynced animation play.
I'm digging through the manuals and tutorials but I'm coming up blank. Any ideas how to handle this? Or what terms I should use to get better search results?

[naive mountain]

Oh sorry.

[long blade]

What is the correct way to export a variable from a blueprint and use it in an animation blueprint?

I am trying to set a proximity based variable to trigger an attack animation in the animation blueprint (which im not sure if this is the correct way to do things either

[woven hemlock]

I found out that match bone from previous clip seem to only work when the animation mode in the sequencer is at 'custom mode'. Anyone have any clues on how to get it to work while I am using a custom anim BP?

[edgy sigil]

Is there a simple way to add either a skeletal mesh or a static mesh to my character control rig in the sequencer to see how it will affect the orientation? Essentially, I don't want to change the mesh, only view what happens to it. Kind of like how you can preview assets that are attached to sockets

[inland grove]

Not sure if it's the best solution, but it seems to be a solution. In your animation states, you can right-click on the animation sequence and "Convert to Single Frame Animation", which allows you to drive the animation using specified time (progress), instead of it following its own timeline.
And you can do the same thing with a blend space ("Convert to Single Frame Blend Space Player").
Then use the same exact "time" variable for controlling both of your animations or blendspaces

[frozen breach]

I remember there was something about loading your rig as FK in the sequencer, its been a long time but see if you search Control rig and FK returns a good tutorial. Sorry Im not of more help.

[frozen breach]

How would you treat/use this time variable? Having a way to play specific parts of a sequence seems super powerful. Thank you!

[frozen breach]

This is how the ThirdPerson template does it to get the Character BP in. You could try this. I'm not sure if its the best way, I just copied and swapped the Class to my character Class.

I wouldnt do those tests in the animation blueprint, I would calculate the attack in the character BP and just send a boolean to the ABP to trigger the right state.

[inland grove]

Increment it by Delta Time on every update, and Wrap it between 0.0 and 1.0 (for the "Normalized Time")
You can multiply deltatime by some number if you want it to play faster/slower

[frozen breach]

Oh I think I get it. Thank you so much for your time!

[edgy sigil]

No worries, thanks for the input. I kind of found the information I was looking for. You can drag in the weapon blueprint into the scene and right click on it in the Outliner and use "attach to" to connect it to your control rig like a child. You can choose the bone or socket to attach it to as well. Main problem with this is that there doesn't appear to be a way to snap the weapon to the socket or bone transform so, you have to eye ball it to the correct location before using the "attach to"

[frozen breach]

There is a way to load the sword model in the skeletontree where you set the sockets. Let me dig a bit. its another thing I know you can do but I never tried it.

[edgy sigil]

Yeah, I don't think that works, adding the preview asset at the socket location doesn't show it in the viewport. I think that's strictly local to the skeleton and skeletal mesh viewer

[frozen breach]

Oh sure. Its just to help you position the socket

You can spawn the sword in your character BP later

for easier use

[edgy sigil]

Yeah, I'm just trying to see how the weapon moves based on the socket it'll be attached to when I make an animation

[frozen breach]

@edgy sigil https://www.reddit.com/r/unrealengine/comments/yef5to/is_there_a_way_to_preview_sockets_in_control_rigs/

Does this help?

There is some gifs in the bottom seems to do what you need

[edgy sigil]

yeah, that worked, cool!

thank you

Yay Happy to help

[crimson turtle]

Hello, I have some questions.

I want to do some animation that is not related to the gameplay.
What will be the good approach? TO animated everything into blender?
To import everything in UE and do the UE animation tool?

Because shader are different between the two application.
And i'm not sure but i feel like the shader of UE are more powerfull than Blender.

So what if i want to do a "cinematic"? blender or UE?
what will be the best tings? learn animation on UE, or on Blender, or even on another third party tool, but put everything into UE for shader calculation,or blender?

[frozen breach]

Seems like you just want to make animation shorts.
Animating everything in blender then sending to Unreal to lookdev, Light and Render is a great idea. If you have ready animations in Blender you don't need to change them in Unreal, they will play just fine.

If you never tried importing models from blender to Unreal, Id make something really simple like a treasure Chest, like a 1h project. Just model something super simple, rig it, animate it opening then try to export to Unreal.

[crimson turtle]

yes, so on blender you take the model that you will put on UE.
You make the animation.
And you import them into unreal engine.. BUT does it mean that i need to have the rigged component on UE? or the animation can be an animation, where i will put material on the good place.
so it will be like animation on characters for gameplay in fact?

my current workflow is

importing rig on UE

importing animation of those character into UE

but that mean im able to play with those characters in fact

so it's not just an animation, it's component animated (characters)

so my approach is already good?

so do I need to have the rigged character into Unreal?

because let's take for example an animation that involve 2 characters

does UE needs to know how are those 2 characters are rigged?

or it's more i have 2 characters, so it's 2 animations, and not just one

even if they are on the same "scene"

[rigid gate]

guys how can i import character animations whic has squash and strecth animations to unreal engine?? From maya and blendee

[inland creek]

Is there a way to get the left hand to follow the weapon grip in sequencer? I have retargeted animations which require some modifications so would be nice to have that. Adding the right hand with the attach command was so easy that I would have thought that same would work with left hand too...

[crimson turtle]

let's assume that i'm more like a project manager tryting to understand what i need to achieve that 🙂

[frozen breach]

When you export your models, you export the skinning, and the skeleton in one .FBX
Then you can export the skeleton with an animation track that will be a separate file.
If you done it correctly you can "play" that animation in Unreal 5

[frozen breach]

Do a test project so you learn the specifics, it will take a few attempts but when you done it once it will make so much sense.

[crimson turtle]

that part i already had with a normal character, with normal game purposes. so i guess it's the same approach

the animation is controlled on Blender, and UE will only display it

[frozen breach]

Precisely

Research the Sequencer tool in Unreal it does what you need.

[crimson turtle]

ok i will check what this feature is

[crimson turtle]

yes that was exactly what i need

to have some control on the animation

[frozen breach]

Nice! Good luck on your project!

[crimson turtle]

thanks 🙂

[frozen breach]

I never used sequencer but cant you parent constrain the box control to the hand? When you can just disable the constraint when you are done.

[inland creek]

@frozen breach Nope, at least I haven't found any other way to constraint movement to an object other than using the "attach" track, but that uses the root of the weapon automatically and does not let me select a socket that I have added to the weapon grip to be used. So I can't make it for example, use the root for right hand and "weapon grip socket" for left hand.

[frozen breach]

https://dev.epicgames.com/community/learning/knowledge-base/pqPG/unreal-engine-sequencer-attach-tracks

Isnt there a way to keep it relative to the attach point?

Its wierd that it snaps to the root

FYI like I said before I havent used the sequencer yet so I'm just assuming since its a really basic feature for animation

[pseudo mulch]

I got a Character with Control Rig from UE Marketplace, and I'm trying to add backwards solve to the Control rig, so I can bake animations to it.
How do I handle Basic IKs?
Everything works fine beside things that make use of IK, like walking animations.

[exotic cipher]

In GASP the traverse is set for mantle, vault and climbing.
So if i want to add more states for example wall leap up, or slide, so i need to run more traces in the existing example as im still unable to understand it.

[wanton ridge]

Could folks recommend some kind of a flowchart I can follow when debugging why a montage is not playing?

I'm looking at the underlying source for PlayMontage() and I'm clearly getting a MontageLength > 0.0f value which makes the logic believe that the montage played successfully, yet the character on the screen seems to do nothing.

I suspect it's some really obvious property I'm not thinking about checking that y'all would have run into 1000 times.

[ivory osprey]

Are your slots set up properly in the animBP?

If the node is being reached, and the inputs aren't returning Null, then it's probs a slot issue

[mossy nexus]

Total noob here. I'm having some trouble exporting my models and animations from Blender to Unreal 5. I have two armatures, one for the weapon and one for the arms, and I baked the animations (manually in Pose mode) and then removed all bone constraints. It shows up correctly in Blender but in unreal the character's left hand is too low for some reason. I had some larger issues earlier with bones not deforming the mesh correctly which I sort of solved by changing the Transform->Forward and Up, and Armature->Primary and secondary bone axis, but this issue persists. Anyone have any idea why this could be happening?

[onyx moss]

a strange thing that we can't open a blendspace and animation sequence at the same time, one has to be closed

which is a problem and extremely slowing down developers

[wanton ridge]

Yeah, thank you, looks like I was using a slot that didn't exist in the ABP that was used by that skeleton!

[brazen marten]

Tell me what the problem might be. I switched to version 5.5. Before that, there was a project on version 5.4 where I had a character skeleton with a bunch of animations. If I needed to add a new animation or replace an existing one, I just dragged the file and the animation was updated/It was created. Now when I add a new one on version 5.5 or update an existing one, my character turns into a horror movie. Tell me how it can be fixed or repaired. There is also a new import window...

[silent ruin]

Initial impression is that it looks like skeleton orientation related issues.
And yes, 5.5 changed the fbx importer. All the options that were there previously should still be there.
Your best chance at getting hte animation to work properly is to check the box above, so it Update Skeleton Reference Pose.
It will likely break other animations.
Strongly recommend study more about why bone orientation is important in your skeletal mesh assets.

[silent ruin]

Look up root motion, and how it affects your character and their animation.

In your case, the lack of root motion, with an animation attempting it with pelvis motion.

https://dev.epicgames.com/documentation/en-us/unreal-engine/root-motion-in-unreal-engine

[silent ruin]

just right click a file and open in a new window.

[onyx moss]

thanks for this info

[silent ruin]

GASP relies on the target object, then the curves on the target object to return proper transform to mantle and vault.
You'll need to expand on the logic on the character to achieve stuff like leap up and slide.

[onyx moss]

it would be nice if they make it simple as double click

it still slow from right click

[silent ruin]

well, you need to take into account 90% of the user with low end hardware can't handle 2 anim viewer

[onyx moss]

with low end hardware should not think of using UE

[silent ruin]

or people with management skills that kept double clicking and left 99 of them open

[onyx moss]

even with high end pc it sometime crashed

[silent ruin]

Well, crashes are usually GPU memory maxing out, null references, or a random file in your VS got corrupted.

Or me being dumb with BP XD

[onyx moss]

yeah mine 64gb Ram sometime got filled

and freezing engine

[silent ruin]

check your skeleton's retarget options (Top right gears drop down where they list hte bones). Set forward kinematic bones to Skeleton, should fix alignment issues.

[silent ruin]

ahh yes, since 5.4, you click on BP while PIE, it'll basically load the whole project into memory XD

[onyx moss]

it means our devices lifetime is decreased 😄

[silent ruin]

Not if you got 128GB RAM💪

And catch it early with end process……

[onyx moss]

hmm great idea but it need more investment like currently i have 64gb of ram and i have to double it

[mossy nexus]

Thank you I will try this

[onyx moss]

and if i want to double it, i have to change the processor too which can actually utilize 128gb of ram, else it will not be in use and useless to upgrade

[silent ruin]

How well your 1P skeletal mesh match with the skeleton’s ref pose will also play into the accuracy of your desired pose.

[tawdry swift]

thank you very much. problem fixed

hi guys, i recently did an animation where my character is jumping, then set it in my aniblueprint where it plays it after boolean is set, after that it goes back to normal idle animation, the problem is when my character is done with jumping,(which pushes him lil bit farword) he blends back to previous location,

i played with root motion is animation, but it didnt give any results

[unkempt kettle]

looks like issue lie with 5.4 bug(?) and need to be fixed via skeletons - will be trying to debug this issue. It was definitely my problem - edited animation working good in editor, but not changed in game

[wanton ridge]

How do you wall debug warnings like this one? I'm running into this ABP warning that only happens when a client character tries to equip a certain weapon, and there's a Listen Server in the mix. It doesn't look like I can just put a breakpoint to inspect the state of the animation as this happens?

I think I vaguely know where this might be happening, but I'd love to put a breakpoint somewhere and inspect the state or some kind of a stack trace to figure out why the value is None

Hi, I have multiple characters with the same "rig". How could they all use the sameABP?

[tranquil cape]

Question: Is it possible to use an IK rig or smth on the animation to get the gun itself to aim at where the camera is aiming? If so, how?

If my question is confusing, I'm trying to get the gun itself to also point where my crosshair. This is a "True First Person" thing, where I just have the camera at the head, it does used an Aim Offset, but it only makes it aim in the general direction.

[mossy nexus]

Hey if you figure this out can you let me know? I'm having a similar problem and I've been stuck on it for a couple days.

[shadow mauve]

does anyone know why its going back, and how to fix it?

[austere adder]

Hey I am using rigify for my skeleton, renamed to "Armature" however, my root motion still doesn't work? Can someone possibly help me?

I found the issue, going to try and fix it

[silent ruin]

root motion is probably off. (So actor didnt' actually move)
And you are blending it back to idle, where the actor started

[shadow mauve]

I have it on, i tried tweaking some variables but its not working

[shadow mauve]

did you have this problem before?

[silent ruin]

make sure they are actually moving the actor.

https://dev.epicgames.com/documentation/en-us/unreal-engine/root-motion-in-unreal-engine

your behavior is exactly this

[shadow mauve]

yup i was trying to do that i made surea root motion from everything is set in AB, but it made actor not move at all

[shadow mauve]

also debugging it is real weird because the main capsule of enemy just dissapears when i am trying to show collision while playing

[silent ruin]

its less about the root motion at this point, you'll need to share what your implementation looks like bp side

[austere adder]

Okay I thought I can figure it out, I am using blender and rigify for my rig. Blender2UE to export everything. As you can see, Blender2UE makes the object parent the "root" bone and then the real root is named to "root1". When I turn off "export object name as root" all animations are broken. I even tried renaming the armature to "Armature" and that didn't work. Any suggestions?

as you can see the pic on the left shows the one named "root" is the object , that stays in place, while the real root - "root1" is moving. So when I try to move my character, it doesn't move.

[unkempt kettle]

I have been fooling with skeletons (after finding comment in a youtube video), and after updating a skeleton in animation, preview animation have been resetted to what I can see in game. So for me it kinda ticks - problem is exactly with skeleton... But I was unable to fix it properly, sorry.
It seems best way is to edit animation in a blender (or other external tool), but for now I just removed this animation from the game.

[mossy nexus]

This might not be relevant to you because I am a total noob, but I found that I didn't have a separate game and control rig in Blender, I followed this video to create a game rig and now it looks broken in blender and unreal the same way. Still have to figure out how to fix it, but it's progress! https://www.youtube.com/watch?v=O-5MXyKyyhc&list=PLdcL5aF8ZcJvS4rui1CyKuFQLBGE4rnas&index=1

[copper sigil]

Hello! I'm trying to do a bit of a procedural offset of the characters arms based on each arm's proximity to another part of the body. Basically an avoidance thing. When crouched, if the hand or lower arm (whichever is closest) is less than X distance from the calf (knee) lift the arm up to avoid the arm clipping through the knee. Otherwise use the normal position.

The problem I'm running into is probably obvious for anyone more experienced than I - I'm using the bones to determine distance and then setting a new position for them based on the result, which changes the result of the distance check...

Is there a way to... cache or store bone transforms prior to an AnimGraph modify node? Sort of an execution order thing I guess. Or perhaps there is a better way to do this, like using a virtual bone to do the distance check (but then wouldn't that virtual bone also get the same offset anyway?)

Here is how I calculate the distances and store them as a 0-1 float for each arm.

And then I'm just applying an offset in rotation based on that float:

You can see it sort of working, but of course snapping between the pre-offset and post-offset distance results

[silent ruin]

just make better blend spaces mate, it'll save you all these trouble

[copper sigil]

That's... not the answer to my question 😅. Also blend spaces are no good here because the movement of the upper body is procedural.

[silent ruin]

If you really want to do it this way, I have a soultion for you about this bit:
" I'm using the bones to determine distance and then setting a new position for them based on the result, which changes the result of the distance check..."

You run a second ABP that provides the "clipping" position, and use those bone positions to return the math to correct your live model.

[silent ruin]

^

Other than this, the other way you could do to avoid the feedback loop is using even more complicated math, estimating positions and rotations based on character's crouch bools and yaw floats etc. Which will infinitely bloat your calculations.

Hi everyone, I'm having trouble creating an animation.

I hope I can get your help, thank you very much.

[zealous viper]

how to have an animation that overwrite all body part's animation sometimes?

[limber shell]

Trying to set start pos over update so that i can change my playback of the walking animation. But it is just frozen, i know that the valye works in update so thats not the problem. I dont want to just change PlayRate as that would not scale well with other beats.

[silent ruin]

take a look at how lyra's animation acclerates their stop animations from cycle, and how they handle fall landing.

[silent ruin]

From the documentation https://dev.epicgames.com/documentation/en-us/unreal-engine/animation-constraint-tools-in-unreal-engine:
"Once you have finalized animating with constraints, you can bake the final result to keyframes. This can be useful if you want to revert to normal keyframe animation to make further edits without constraint considerations."
^key word is you can bake, not HAVE to bake.

The animation behavior in the result anim sequence might look fine without baking the constraint, can you give that a try?

[limber shell]

Imnguessing you mean lyra demo scene ? Also in no animator, prefere some pointers if you can bcs i wont understand the lyra demo probably

You mean that its constraint that overridea my attempts ? Bcs its not my animation s

[silent ruin]

you are encroaching on animator territory with your attempts lol.
You have the ability to add logic into the OnUpdate OnBecomeRelevant and OnInitialUpdate of an anim node, and use it to modify the animation.

[misty dagger]

my version of copy motion

[silent ruin]

And you can use Sequence evaluator to modify the animation further.

[ivory osprey]

I know you can cache poses in control rig, maybe that could work?

[limber shell]

Thank you i will try this , but is it on to run the logic for the variable i want to save and update in event graph in animation blueprint or do i need to run it in another bp entirely and save it in a exposed variable in animBP?

[silent ruin]

there is also Sync Markers

[limber shell]

Just need the simplest way to do this:

So in unity i would do this> if this was animation.

void Start()
{
light = GetComponent<HDAdditionalLightData>();
}

void Update()
{
    if(light == null)
        return;

    float currentBeat = Reactional.Playback.MusicSystem.GetCurrentBeat();
    var value = animationCurve.Evaluate(((currentBeat + offset) % beatFrequency) / beatFrequency);
}

[honest bobcat]

Any advice on how to find good animations?

Specifically I'm looking for dagger/attack animations,
and by "good" I mean ones with "back to idle" animations and hit-react as well.

I don't mind paying for them, just not sure how to find one that have all of these.
I just bought one, thinking it would have it, and it only had the combo one ( and that was bad too 😦 )

[limber shell]

Either hire a animator , or get some animation pack and alter them in Unreal. Manikin came with many free a while ago

[honest bobcat]

@limber shell

Either hire a animator
Expensive. That's why I was looking into packs.

Manikin came with many free a while ago
Manikin? what free ones?

or get some animation pack and alter them in Unreal
I have an animation pack actually, I guess that's an option. not a fan of it though xd

[limber shell]

https://www.unrealengine.com/en-US/blog/game-animation-sample

[honest bobcat]

oh yeah I know that one, using it. Although I think it's a bit misleading; more like 500 "Animation Sequences"
e.g. "walk" is like 200 or something xd

[limber shell]

well if you need more base animation than 200 you doing something wrong, Retarget it to your own character if needed and alter it if needed and that should get you going until you have the money or have someone to collab with for animations

https://www.youtube.com/watch?v=s4Y2nKWpZ44

Blender and making your own animation is fun tbh . or maya

[honest bobcat]

@limber shell

well if you need more base animation than 200 you doing something wrong

Not sure how that's related. I mean I'm looking for combat animations which aren't there, as I already said ..

[limber shell]

i get the first part making a function , but have no idea what nodes you found

Ok there was dublets everywhere, but still could you give me some more context of what im actually doing here @silent ruin

Hi Guys, I am using blender and export my meshes and animations as a gltf file after giving up on fbx. It mostly works now importing them into Unreal BUT when I add new actions/animations to a blender file, it wont be added to unreal when I reimport. How do you guys manage such things? there will always be the case that you might add another animation later in development

[silent ruin]

https://www.aaronkemner.com/animnode-reference/sequenceevaluator/
This is your best friend as someone tackling the ABP.
The idea is you are accelerating/decelerating the animation based on your desired play rate, or even jump to a specific time (Think using curve to drive which beat your animation is on)
You need an evaluator to do this.
"Outputs a pose from a specific point in a sequence. Instead of moving on with passing time, the time the sequence is evaluated at is passed in as an explicit time."
Anim sequnce just keep moving on, evaluator could jump to places.

Aaron Kemner is my hero XD.

On the marketplace (Fab), look up "RamsterZ Free Anims Volume 1", it's a free pack. Also try your luck with mixamo.com (those just need to be retargeted).
Idk how lucky you'll be with finding groups of animations that transition into each other, but you can look for something that's close enough and play around with blend timings.

[slim topaz]

you can use mixamo, but you'll need mixamo converter too, the converter change animation rig to unreal rig

[inland grove]

Take a look at how Unreal does it in the default third person project. ABP_Quinn is a child of ABP_Manny. All the graph logic is in the parent, and the child is able to override animations with different ones.

[spare kiln]

cool thanks! 🙂

[spare kiln]

Also this is probably best practice, having a parent class right?
So to not have all the variables and stuff duplicated in ABP's

[inland grove]

Yep. (As long as all your characters perform same actions)

• and if there are some special actions that specific characters perform, Montages can take care of that

[flint niche]

The animation is correct if you drag the progress bar, but it still errors out if you click play button.

[silent ruin]

so it plays incorrectly if you didn't bake it, which is why you are trying to bake it?

Oh dude, try and bake in world space

you are doing local right now

maybe that'll help

since you are dealing with IKs

[spare kiln]

I'm just wondering if there is a case where something needs to be different in the AnimGraph, if I could use Linked Anim Graph's or something to override things.

[primal fiber]

It's a bit annoying they did game animation sample in UEFN and it's not really practical, and retargetting or exporting the animations is harder in this. Even using the regular UE mannequin is hard to do properly in this. I was hoping they'd just do a plugin with animations only, targetted to UE5 then we would also save disk space and many pros of this compared to that.

[inland grove]

Nah, I think child has to use parent animgraph, it's only meant to play different animations and implement custom logic in Event Graph. If your characters will have many different behaviors and functionalities, might as well make separate ABP's for them.
I guess you could also make some portion of the parent graph inaccessible for parent itself, meant specifically for children that meet certain conditions?..

[spare kiln]

Because things like Falling/in Air or Blocking might be share by all, but then things like aiming is just partially needed and may be handled differently.

[inland grove]

You can still add it to the parent.
All your characters will be able to aim, but not all of them will actually aim during the game

[spare kiln]

Yea thats true

I just feel like it's a necessity, since my ABP's are growing, and the having am minor change woud mean having to change it everywhere, same for extending them and thats not viable.

[inland grove]

indeed, it's better to have a parent. That way you only add the big change in one place, and then any children that need it will use it, and others can ignore it

[patent vigil]

Hello, can someone help me in dms?? i really need some help regarding first person animations, i cant figure out how to make the camera move alongside with the head, and also how do i make the player position update alongside the animation

my ingame camera is atached to the player head, so the position moves with it, but not the rotation

[flint niche]

No It works when drag the progressbar, when click play it still brokes

Still broke without bake

[vapid light]

Hi, I have some pet assets and they have skeletons + animations but they're missing the AnimBP, any help on next steps?

[honest bobcat]

@inland grove @slim topaz Thanks, will try both options!

In the meantime I tried animating on my own, just to play with. Got some weird artifact in the beginning though - any idea why/how to fix it?

It's gone by 2nd frame (#1), and not part of the sequencer

[austere adder]

can someone please help me?

Like ive tried renaming the Armature to root and the actual root something else completely. That doesn't work either, its still the same result.

[steep umbra]

Hey all, I'm running into a strange issue with specific animation montages meant for holding equipment. These animations will jerk or jitter slightly when they loop but others in the same slot group don't exhibit this behavior. I've tried moving them to different slots and even exporting the anim again but they do the same thing. I see some people have had this issue in the past on the UE forums but I haven't found a solution. Anyone run into this before?

I should note that they play and appear fine outside of gameplay

So nvm I think I figured it out but it's VERY strange. If you're using motion matching like I am, having that character BP in sequencer and exporting the animations causes odd behavior like this. Not entirely sure why but making another copy of the character with nothing but the mesh and capsule and using that to bake the animation from Sequencer was the fix. 🤷‍♂️

[silent ruin]

were you able to try the bit I mentioned about baking in world space/local space?

[dark vigil]

I'm trying to learn how to animate using the control rig, but when I bake my animation to the control rig it doesn't animate. I see key frames in the curves editor, but the manny doesn't move at all. Am I missing a step or something? I thought I just needed to bake it to the rig and then could edit the sequence from there.

After baking all the rig controls vanish from the manny, and if I select the controls from the anim outliner, they are in the wrong location and don't move the manny any more. I'm using 5.4.4

[inland grove]

I think in the sequencer, you have to first delete all existing tracks below control rig, then add new animation and bake it (iirc).. but there's also another method, I been using this one lately. See how this guy does it (First 5 min of the video)
https://youtu.be/SKGYWBJRfqo

[dark vigil]

Hell yeah! Thank you, that method worked for me, so now I can move forward. Also that looks like a very good video, I may just follow on! I've seen a few other videos from him, but not that one!

[austere adder]

My skeleton is fine , especailly in blender. But why are my animations looking like this? These animations are baked and complete.

skeleton looks like this:

[long temple]

wasnt too sure where to put this but ive been having trouble with cloth getting to work with my animations

so for example at this pose the part of the coat is clipping through the leg

but no amount of physics asset changes will do anything to resolve this it seems

the only way i was able to fix it was by shaking the mesh lol to get it to be unstuck

[inland grove]

Does your animation start in that pose? I believe it should work fine as long as you gradually transition to it from idle.
I'm not sure how to prevent it from clipping when you start from that pose though.

[long temple]

okay thats good to know at least

Yeah that wouldn't necessarily be my starting pose thanks!

[tawdry swift]

any tips on how to get good proper head bobble for first person realism?

[wind moss]

Hi I was wondering if anyone might know what is happening with my animations when importing to unreal from blender, and bleding them together in a aim offset for my "look around" blends.

in blender

but in unreal

His feet shift up and down when hes looking left and right

but this doesnt exist in my animation in blender.

Now I notice when I change my additive animation type from "mesh space" to local space

it will fix the feet in the individual animation asset, but when I save them, and go to my blend space, my character will completely disappear.

[idle maple]

does anyone know how to loop a montage?

[rigid geode]

Does anyone know how I can make my Game Animation Sample have a more feminine look without changing all of the animations?
Is there a blend I can do in the AnimBP? Blend it with something that is feminine?

[silent ruin]

You can change how your blend space blends between the changing variables.

Adjust teh Smoothing Time in the blend space*

[silent ruin]

setup logic in your GameplayAbility or a function, that resumes the montage when it ends.

[silent ruin]

You can't, let's take walking as an example, female character naturally have a different hip structure compared to male, resulting in different hip movement.
And the visual representation of femininity is an artistic choice, and unfortunately there won't be a one stop solution to it mathematically.

[silent ruin]

you might be feeding your additive animation the wrong ref animation, I'd double check there.

[silent ruin]

a technique you can apply is to setup a postprocess ABP.
Have a kinematic root to your coat's physics bit.
Use the leg's rotation to affect the kinematic root so the simulation could start in a unclipped alignment.

[silent ruin]

My best guess is that your blender file was not setup correctly.
A common mistake is not setting the scene scale to 0.01

This doc covers lots of it.

[terse cosmos]

hi, is there any way to split the logic of Animation Blueprint? I'm looking at an example from Lyra and there is a very massive Anim BP. For a regular BP I would use something like Blueprint Component but I'm not sure if there are analogs for Anim BP.

for now I'm thinking of transferring all this logic into a character, decomposing it normally and getting a conditional "snapshot of the state" in Anim BP - what do you think of this idea?

[zealous viper]

does anyone know how does slot in animation and blending works?
I want to play a animation with only right hand for shooting that doenst' affect the other body parts

[formal whale]

Anyone ? 🥺

Why When Placing Rig The Fingers Reset When Rig Is Placed?

Layered Blend Per Bone

[cinder linden]

Heya guys there's something wrong with my modular ctrl rig. My root has 4 other chains but it only let's me select one

It seems to create the socket from the first children of the root and I think that is the thing preventing me

[cinder linden]

Yeap that was the issue now that I added a root bone that is not the pelvis it works

[true token]

[formal whale]

up

[flint niche]

Tried that. Didn't work.

[silent ruin]

this bit here, you are still using local bake, maybe it just need to be baked in world space.

Another thought is if your character's root is at 0,0,0 this bake might give you a good result.

[rigid geode]

[strange sigil]

i'm in the middle of a game jam - is there a go-to way to use mixamo characters (skel meshes) with unreal's sk_manny? all my ABPs are using UEs SK_Manny
I find lots of anim retargetting resources but no rigging solutions.. might be a dumb question

[rigid nacelle]

I couldn't get the new motion matching system working perfectly for me yet. So I wonder without that, what is the best way to make transitions like stand -> crouch appear smoother. Is it with animation timelines?
For jump I have made separate jump start/end, and just make an animation timer to decide when to go to the fall loop. But I am not sure if that is precise enough for a multiplayer replicated game.

[zealous viper]

I might need some additional explainations,
the top and bottom defines the character is looking up/down and the feet animation respectively
and I can't get the right hand to do the shoot animation
both when I use the state machine, and when I tried to play anim montage in blueprint
(and can't drag animation montages to the anim blueprint)

[tender swift]

Guys, to do the start move with turnAround it is recommended with the root motion activated or deactivated to make my character turn

[silent ruin]

You will want to run your AO logic and blend them together after the arm animation.
I believe they are running before the arm animation are blended in and that causes problem when you blend arms back in in mesh space.

[light plover]

any idea why this aim offset blend space would cause the character scale to get blown way up? The original blendspace didn't do this, but after retargeting it onto the UEFN skeleton I get this

[zealous jewel]

Does anyone know how root motion works in relation to various forces being applied etc?

Suppose there's a character moving with root motion, and during the animation some sort of impact is applied to the character capsule, which gives the character some sort of velocity. What will the root motion do? Will it simply override that velocity? Or does it simply add some translation offset (based off the animation) on top of any sort of physics etc.?

[ivory osprey]

That's a really interesting question actually. If I have the time I'll try and test that! My method was gonna utilize an animNotify which uses the LaunchCharacter node 🤔

[ivory osprey]

Usually massive scale issues indicate a problem with additive settings. Maybe make sure those are all in order?

[light plover]

Yeah. I did some digging and I think my problem was I was using an aim offset, but adding it in by doing a blend by bone with an override, whereas aim offset should always be additive. I'm working on swapping to a blend space instead

[zealous jewel]

Let me know the results please. Based on some searching, I'd suspect that the delta-translation is simply applied / overrides the previous velocity fully.

    ENGINE_API FVector ConstrainAnimRootMotionVelocity(const FVector& RootMotionVelocity, const FVector& CurrentVelocity, FCharacterMovementComponentAsyncOutput& Output) const;
    ENGINE_API FVector CalcAnimRootMotionVelocity(const FVector& RootMotionDeltaMove, float DeltaSeconds, const FVector& CurrentVelocity) const;
``` these two seem to be the relevant functions,  so it seems like the behavior of overriding the velocity could be adjusted (to something like e.g. ... interpolate the current velocity towards the current target root motion velocity) or whatever.

[royal cargo]

Does any one know if UE2Rig addon for blender works ?

It gives me no result after pressing Convert, and on all videos tuts i saw it worked well

[viscid willow]

A lot of this kind of data that you want to get from the character you can get through Property Access without having to calculate or store variables in the ABP: https://dev.epicgames.com/documentation/en-us/unreal-engine/animation-optimization-in-unreal-engine#propertyaccess

[worldly anvil]

Hello, does anyone know whether EventBlueprintUpdateAnimation might be called more frequently than AnimGraph?

I have a boolean flag which is raised for one frame inside the update function that should be used by the AnimGraph, and then I set it to false the next frame. However, when I test my game in packaged build, that behavior is half consistent.

Don't really want to go in much details here, but from what I could find out it seems like the flag was lowered before it was used inside of an OnUpdate of the active SequencePlayer.

If the SKM update and regular update are async, how else could I get the behavior I get working?

[gritty vessel]

Hello, I am trying to retarget some animations I purchased from Unreal marketplace and only the FK bones are being retargeted. The IK bones are detached after retarget and that is causing issues with leg IK and some other stuff
Im using ue 5.5 and I have also tried it in ue 5.4 with the same results

Any pointers about this behavior? Is it something obvious that I have missed?

[fathom bluff]

Does anyone know if ARkit livelink works with phones as the IP hotspot? I can’t seem to get unreal to detect my phone and am wondering if that’s why

[terse cosmos]

in that case we will lose the benefit of calculations in the Worker Thread. I have not found any way to separate the logic except doing it at the C++ level.

[wicked sequoia]

How do I make turn animations instant (or remove turn animations completely and align the mesh to a direction) on the game animation sample project?

[terse cosmos]

disable Offset Root Bone

[wicked sequoia]

Where? Its already disabled in the abp

[terse cosmos]

check for any other mechanisms to change Root Bone

[wicked sequoia]

Swapped rotation mode to "release" and it works perfectly, thanks king!

[flint niche]

Like this?

[silent ruin]

give it a shot.
"父项" means Parent Space
"世界“ means World Space
The behavior of your video from previous video, shows the bone baked to the middle of no where, which made me suspect the IK targets we baked relative to their own parent. (The tank, and the character's root).
Hence, if we were to bake from their own world space, the result should visually remain aligned.

Just trying to apply traditional Local/Parent/World space transform copy/bake thought process onto what I'm seeing with your rig setup.

[flint niche]

I solved it, cause the parent of the hand ik also have a parent constraint, I delete and it solve.Thank you very much for your help.

[short rose]

I am retargeting a set of non-character rigs and I am only getting rotation animations, but not location animation. Does anyone know what I might have missed?

[naive mountain]

Root retarget chain?

[forest leaf]

I don't know if I should ask this here, in animation, or in physics, but I (an absolute beginner using UE5.4 for a new project at my VFX job) am trying to add tail and ear physics to a custom anthropomorphic animal character that is receiving live mocap animation through Rokoko studio.

I have created a physics asset for the tail where I added collision capsules just on the tail bones, and tweaked the constraints so that as I hit "simulate", the tail flops down to the ground with gravity.

I then created a new animation blueprint, connected the input pose to a "rigid body" node and then to the output pose, and in the rigid body node I've selected the tail physics asset.

I then applied the blueprint to the skeletal mesh as a post process anim blueprint. But nothing seems to happen at all. In videos I've watched that's all you needed to do. Nothing happens if I simulate, or if I enable the post process animBP in the preview windows of assets that are using that skeletal mesh as the preview mesh.

What did I miss?

[silent ruin]

your skeletal mesh's retarget options (Gear Icon top right of where you see all the bones in a list).
Set it to be Animation or Animation Scaled.
If it says skeleton, its rotation only.
Have fun!

[silent ruin]

Set the physic body to simulated in the Physics Asset. Right click body, set it from default/kinematic.

And if you are running it as a post process ABP, keep the rigid body on postprocess ABP.

You may wish to make the root of the tail kinematic to retain some control over it.

[forest leaf]

That was exactly it! I think I just assumed that "default" meant simulated, as I'd tried to set the root as kinematic before to keep it fixed as the others fell, but it never occurred to me to actually set the others as simulated rather than default

although, now even tho in the physics asset it collides with the ground, it doesn't do that either in the editor or in other assets' preview windows

[last patrol]

Does anyone know why the layered blend per bone changes depending on the animation my other arm is playing? I tried different blend settings and I can't figure it out. I'd like it to be that the animation position for left arm is always the same regardless what the right arm is doing.

[silent ruin]

Rigid body is cheaper because they can’t collide with world geo

[silent ruin]

Need to set it up with
Torso as input 0
Clavicle l
Clavicle r

[forest leaf]

oh so would I need to do additional setup for it to collide?

[last patrol]

So something like this? Confused if you mean Torso as input 0, unless blend pose 0 is suppose to be for torso/spine

Ah, it seems like it does work when blend pose 0 is set to spine, then blend poses 1 and 2 for the right and left arm.

although it seems like the position of the hands are now very different. I suppose I'll have to edit all the animation sequences so the hands are in the right spot

[short rose]

Thank you! They were set to "animation". I am guessing the SKs are bugged. I will dig around a bit more

[silent ruin]

you need to go the set simulate physics route for this.

in gamethread w/ BP/C++ code.

[silent ruin]

Think slot 0 and 1 as stuff for overriding the torso base animations. Yes
