[coral skiff]

Okay so i want to add a premade pose from a pose set from booth. I dont know which one i am getting i just wanna know how i do it first. Then add it to my model in unity. I kinda know where to put it but it never works and i cant find a nice tutorial...

[warped gazelle]

i have made a model with 2 actions that are a bone moving but that bone in unity is completly bugged and doesn t get moved. anyone know this pipeline and this bug?

[astral lion]

foot sliding, idk how ti fix it, i have tryied everything.
I made a character (custom rig with ik and fk) in blender, made an idle animation (60 frames), baked the animation and putted the right choose in the export (fbx).
In unity, rig as a humanoid, adjusted everything, animation compression off, loop pose, bake on every field.

but i still see some light slide, idk if its the animation or its unity, i searched on internet a solution but i didnt found it, if anyone had the same problem and know how to fix it, please, help me!

Sorry for my english btw.

[pastel yacht]

Hey guys I'm sure you have answered this already but ultimately my Mixamo models are not showing up in color in Unity, please let me know what to do

[pastel yacht]

nvm I figured it out, the extract textures thing was confusing at first but I get it now

[halcyon nimbus]

drag the textures into the model

[wanton trellis]

did you enable foot ik inside of the animation state in the animator?

[pastel yacht]

That isn't how I fixed it and wouldn't work btw

[halcyon nimbus]

it does if u click on the model first before dragging them

[light badge]

TLDR: how can i move 2 separated fbx mesh with one animator? (aka how can i tell the mesh to use the bones of the full body mesh so they are synced? is that the right way or i'm looking at it wrong? )
Also if you have links that explain the process send them my way. i don't just want to make it work i want to understand

Hey yall, i'm a prog who has to implement animation.
I want to have arms in fps and the body casting shadow
but for my other player i want the full mesh to be visible.
Normaly what i'd do is ask my tech art to export the model in 2 mesh so i can toggle the body to be shadow only, etc. (or use shader magic)
but i'm on my own and the asset i'm using are providing a mesh (full body) and another mesh only arms.

[agile solstice]

Why not use two identical animators that you control together

[light badge]

I could but I was under the assumption that having 2 animator for one "system" was a bad fix to my lack of knowledge
is that not the case?

[agile solstice]

Same as having two animators between two different "systems" or transform hierarchies
No worse than that
You could alternatively copy the transform values from and to the corresponding bones in LateUpdate, but I'm not sure if it would make a practical difference

[halcyon nimbus]

hi im honestly new to animations entirely, i already made walking , idle animation and connected it to entry tho how do i connect the walking animation and make it play whenever the player moves, and when the players stops it goes to idle again

[agile solstice]

[halcyon nimbus]

thank you so much

[agile solstice]

I recommend paying extra attention to the transition settings like exit time, delay and transition length
The defaults are not useful for most kinds of transitions

[sacred wind]

Hey everyone, I just downloaded the universal animation pack by Quaternius and I was wondering why the character gets sort of mangled in all of the animations when I tick Bake Axis Conversion on even though it says to do so in the import instructions. Does anyone know what is going on? Turning it off fixes it but the character faces the complete wrong direction in the animations

[wanton trellis]

is the pack designed for humanoid or generic characters?

[sacred wind]

The import instructions also say to set it to humanoid

[wanton trellis]

so your character is fully set up as a humanoid?

correct avatar and everything?

[sacred wind]

Yeah

I checked the avatar bones and everything seems to be configured correctly

[wanton trellis]

does the documentation mention any "known issues"

[sacred wind]

For some reason it seems like I'm the first one to experience this

Weird

[wanton trellis]

try it on a different humanoid model

[sacred wind]

If I use the Unity model in the little animator window it looks about the same, however maybe I need to try a different avatar

[gusty garnet]

could it be that your parent gameobject is causing this by any chance

try it on a new empty gameobject with default transform

[crimson cave]

Not sure if this is the right channel for this but can anyone help with why my right hand bone on the rig has split into two, been following an online course to get to this point and only just noticed this issue when I added in the red and white gizmos,

It's from mixamo and all the animation is working fine however I think its why the characters aim is not working properly

[wind silo]

is it possible to use root motion with an animation clip I create in unity? all tutorials always have imported clips where they match the avatar on the import settings which I cant do cuz I've made the animation itself in unity...

[celest crag]

Some info here https://discussions.unity.com/t/make-root-motion-in-animation-clip/540337/4

[wind silo]

ah yes the unity way. it works but you kinda also have to do it urself. love it

[light arrow]

I'm trying to use the cinemachine but everytime I place down any sort of camera from it. The postition of my main camera moves with it. I'm trying to keep the camera from moving but unsure what's causing it

[wind silo]

iirc cinemachine cameras arent actual cameras. they pretty much hijack your real camera and transform it. cinemachine itself it basically just a transform that is the parent of a unity camera.

[astral lion]

yes i did, somehow i managed to fix my problem but thank you!

[ornate vine]

why tis not blending

[long pulsar]

anyone here made a combat system before

if so how did u manage to sync frames and frame windows with atks?

did u use animation events or normalized time

[terse gust]

probably your transition time is too les

[wanton trellis]

altought im not sure if its inefficient, i almost always use animation events for stuff like that

saves you the trouble of doing timing calculations manually, but can be a bit of a bitch to keep track off

[nova dagger]

Ahh the woes of object animation and origin points from blender, seizure warning

[wanton trellis]

is there anything you need help with here in particular or?

[ornate vine]

there aint really a transition time option

[terse gust]

yah ofc, i mean;t

[terse gust]

there is a transition duration field

[terse gust]

check this
https://docs.unity3d.com/6000.3/Documentation/Manual/class-Transition.html

[ornate vine]

i think ill just kill mysefl

[terse gust]

wdym

[terse gust]

did it work? (i assume it did XD)

docs are always the best

unless badly documented

[mystic yoke]

Hey so im having this issue with my animations and it's breaking all my animations legs

[wanton trellis]

are your animations generic or humanoid?

[mystic yoke]

how do i check?

[wanton trellis]

you can check with each clip in the rig tab iirc

also when you imported the animations did you set them up correctly in the inspector?

also make sure your states have footik enabled

[mystic yoke]

yes it's humanoid

[mystic yoke]

where do i go to access that

[wanton trellis]

directly in the animator itself

should be in the inspector

[mystic yoke]

oki

ill see

hello?

[mystic yoke]

i figured it out

[modest moat]

Hey, I was just blocking out a walk animation, I have IK setup for feet but have disabled them temporarily for animating (I plan on blending IK and animation clips later) but for some reason, even though the IK is disabled (using Animation Rigging Package) the legs don't move when I press play to test. Here's a gif:

As you can see, before I press play the legs on the walk animation move. When I press play and it gets to the walking animation, it just doesn't, even though the weight on the IK is turned off. Anyone have any ideas what this could be?

[modest moat]

Weird...I kinda fixed it. Even though I had the IK disabled, the constraints were still active and just made them not move at all.

[ornate vine]

nu cuz like this isnt with the animator this is with timeline

i just made it override instead

[terse gust]

good to see it worked, i have no experience with timeline lol

[modest moat]

Hey, so I've been encountering a ton of issues with attempting to combine animation clips with ik foot placement for a walk cycle. I'm really struggling because I seem to have done something wrong that changes this seemingly simple task into something extremely difficult. My main issue I'm currently facing is, despite turning IK off via turning weight down to 0, when I click play and test my animation clips out, the joints in the animation rigging package's multi bone ik script basically refuse to move according to the animation clip.

(Clip above is an example, the fix I had previously has both stopped working and didn't fix the main issue in the long run)

Does anyone know of a step by step tutorial, that includes combining walking directional animation clips with inverse kinematic foot placement?

[terse gust]

firstly, what do you want exactly? from above it seems like you wanted to create clips using animation rigging directly

[agile solstice]

You should show where each component is in the hierarchy and which bones the clips are controlling
Also don't use gif for video, use video formats like mp4 or webm

Animation Rigging is very particular about where its components are hierarchically so they don't conflict with the animator

[modest moat]

I want to blend animation clip based animation with inverse kinematics for feet to align with ground when possible.

[modest moat]

The hierarchy should be fine. I've done lots of animating in the past just never with IK before. The clips are controlling the entire skeleton as the animator component is on the pelvis bone.

The 'IKRigs' include things like the targets and hints for the leg IK.
The Rig component is under 'InverseKinematicLogic' and children of that, 'LeftLegIK and RightLegIK' have the two bone ik constraint components. Idk if this is much help

[agile solstice]

Documentation says Hints and Targets should be under the Rig component
Not sure how it could be causing the issue but I suppose it's possible

There's also more than one way to turn off the IK constraint so I'd try all of them

[modest moat]

Oh. okay. Thanks I'll try that. Yeah I realised that I might be overcomplicating the IK logic I planned to apply later so a lot of my setup might have been too meticulous and actually counter productive.

[knotty leaf]

What exactly does that mean?

I'Ve created a very simple animation with the unity animator and I'm unable to link that or edit the 'Has Exit time'??

😭

[terse gust]

close and re open the animator window

should be ok

also what version

[knotty leaf]

6.3.2f1

[knotty leaf]

tried like 5 times. Made a workaround by going over an empty state with an additional trigger

[terse gust]

wdym

[knotty leaf]

this works

this causes my error

new state is an empty

[terse gust]

odd

everything working fine in 6.3.0

[terse gust]

does it prevent you from editing?

if it doesn't you can ignore it

[knotty leaf]

Yeah it doesnt allow me to disenable exit time or add constrains

I mean codnditions

[terse gust]

lol, might be a bug,

did you try restarting

unity

[knotty leaf]

5 times

[terse gust]

XD

new controller?

[knotty leaf]

pc reset

Was my 3rd animation in that project

Idk

[sterile vine]

have you tried resetting the library?

[knotty leaf]

That i didnt try

[sterile vine]

also, have you tried updating to the latest 6.3?

[knotty leaf]

Not yet

Might do that tomorrow

[woeful wyvern]

Hi all, This is now driving me absolutely insane. Every single time I've tried Unity's IK/Rig system it's never worked, even following tutorials step by step.

Could somebody please for the love of all that is holy take a quick look at this vid and see if you can see where I'm going wrong please. 😕

https://streamable.com/xb13qa

[woeful wyvern]

uuuh, okay, so after nearly an hour working on something else, it literally just decided to start working. lol.

[robust perch]

Is there a way to stop animation rigged bones to not break? Like using constraints.

For example, I know of twist chain constraint or multi rotation constraint but that's supposed to follow a target, not necessarily clamp the angle of rotation

do I have to do all that manually?

[agile solstice]

"Break" in what way? Breaking can happen for many different reasons
Twist chain rotation is interpolated from the rotations of the Targets

[robust perch]

Break in the way that the child bone rotates where it shouldn't relative to the parent bone.

I just found about twist correction constraint and am testing it

[agile solstice]

It "should" rotate, as far as twist chain is concerned
Unless you mean some specific unexpected rotation

[robust perch]

I might have accidentally solved the problem with twist correction constraint that I hadn't considered solving

@agile solstice the transparent hand is the origin hand that moves via transform and IK and the black hand is the rb puppet hand (made a system similar to puppet master let's say)

turns out a lot of my problems weren't due to the joint or rigidbody settings of the puppet hand, it was due to unnatural rotations of the origin hand

(the puppet hand tries to match the origin hand)

[main quiver]

When I try to rotate this parent object along Y, it also modifies position X and Z values. I'm not sure why.

[sterile vine]

you aren't rotating from the pivot

[main quiver]

Oh. If I select pivot, it's showing the pivot too far. I basically created the parent by selecting "Leaf" gameobject and "Create Empty Parent". Shouldn't it by default be positioned with leaf?

[agile solstice]

~~By default yes ~~
Actually with nested transforms it seems to work so that the empty parent is created at the transform of the parent GO above it

[main quiver]

I'm confused. So how do I make it work? Do I need to move the pivot? If I select Pivot option and move, it actually moves whole thing including leaf. I basically want to animate the parent, and child should follow the parent.

It works fine for Position, but not for rotation.

I think I found easy solution. Create empty, then drag a fresh Leaf prefab instance on it. Now they're aligned.

I will try more to see if it gives issue.

[sterile vine]

make sure the objects are where you actually think they are, aka where the pivot is

[agile solstice]

Or create the empty as a child of the leaf and swap their relationship
Or swap their relationship, reset the empty's transform and swap again
Or unparent the leaf entirely before you create an empty parent

[main quiver]

Yeah, after doing that I could see pivots are almost at same location as center now.

[wanton trellis]

if you preview the reload animations inside the inspector with the robot model, do they play correctly?

[robust perch]

This is still causing issues for me. You see how the elbow (the ghost white elbow) breaks when I make a small change. I assume it goes back and wraps around from the other side.

Is it really an impossible position? Should I also rotate the hand as I move left to right so it never breaks like this?

[native pewter]

Hey, my character has 2D eyes with a spritesheet for expressions. I created a custom material for each eye, with a property that lets me scrub through the spritesheet using an integer value. I just created an animation for my character, and was wondering how I can animate my eyes in-engine using the material/shader I created. Thanks!

[glad cape]

no idea if that was even a bug, but those buttons were greyed out for some reason, and they suddenly started working again after like an hour of trying different stuff. does anybody know what that was about? i found other people talking about this online but couldn't find a fix/explanation

[native pewter]

Is it possible to edit the animation clip and keyframe in material properties for each eye material (left and right)?

It appears that material properties with the same name show up only once for the animation clip

which is a huge problem

Is scripting the better solution here?

[agile solstice]

Yes
When a material property is modified from a script, it's automatically made into a unique temporary material instance (which can be created manually as well)
Animation clips have to refer to a specific material
A clip can keyframe a custom component that controls the material instance properties however
It might be possible for a clip to modify materials of a specific renderer together with a script that replaces them with runtime instances first, but doing that doesn't seem to have much of an advantage
If you've got a script between the animator and the material properties, you can easily process or override the keyframe data if needed without having to alter the clips or the animator

[agile solstice]

Iirc this happens when you've selected a clip without also selecting a gameobject that could be used to preview or modify the clips

[steep cairn]

you gotta select an object

Big Problem.

Started using Avatars (it worked before, on an enemy) and when I tried it on a player, it just stopped working.
In the editor, the animations play fine, but in-game, even if it shows that it's playing the animation, it doesn't play any.
any further questions welcome

nvm figured it out

[native pewter]

I ended up getting this to work really well

[cold jungle]

Does anyone have any good tools for rig retargeting? I got a custom humanoid model that I'm using to replace my Mixamo YBot, but I can't figure out how to retarget the old animations to the new character model.

[wanton trellis]

if they are both humanoid then theres not much in terms of retargeting you have to do?

they just both need to be set up properly and thats it

the animations should work universally across both given the animations are made for humanoid characters

[wanton trellis]

but also consider that even humanoid animations can look wildly different because they might be animated for different porportions

[glad cape]

just tested it and yeah you're right thanks

[glad cape]

yeah thanks for the help🙏

[undone hearth]

i dont know if this is the right channel but i would please like someone to help me with animating my enemy if anyone has time to help that would be wonderful 🙏

[barren mortar]

The "humanoid" rig is Unity's way of retargeting

[last halo]

i noticed animated objects dont loud the pngs coreclty on off brand phones but on otheres its fine whys this happen

[jagged patio]

the tool handle is not where it is supposed to be on my rigged model. it was working fine moments ago but while animating it just changed out of no where for no reason. it should be at the green circle

nvm

[shell river]

I’m importing a character from Blender 5.0.1 into Unity 6000.3.2f1 and running into an issue that I can’t pin down. I don't have problems with any other bones except the fingers. Just a simple wave won't transfer over. i've looked at documentation and youtube, but it just seems like unity isn't picking up these bones and i was wondering if unity expects a certain set up for "humanoid" models, or if this is a possible settings issue?

[tribal crypt]

Has anyone played around with this idea before?
The rig automatically balances your pose above your feet.

[agile solstice]

Interesting idea!
As we move as bipedals we do it by shifting the center of mass to be unbalanced in the direction we want to move
That system seems like it could support that

[agile solstice]

If you se a Humanoid Avatar the configuration needs to be correct
Humanoid Avatars aren't necessary unless you want to use Humanoid features like retargeting or foot grounding IK

[wanton trellis]

If your model is humanoid i dont think its set up correctly

Looking at the rig in blender you have multiple broken chains

Youre either going to have to adjust the rig or set your model to be generic

[wanton trellis]

Also for models set as humanoid you have to explicitly assign the bones in the avatar once you generate one

So it could be failing there too

[shell river]

@agile solstice @wanton trellis thank you both, setting it to generic ended up working. I also it had moved at some point during the night away from 0,0,0 in blender (oof). @agile solstice i'm going to be making several monsters are you saying foot grounding ik is only for humanoid or just more automated?

[grim tiger]

how to fix this? this is a free asset called Survivalist

[grim tiger]

the animation looks normal

guys i think i found the issue but cant fix it

the root is rotated by -90 and i cant rotate the root alone to fix it

[shell river]

is the character controller clipping the floor causing him to float? that can happen and then if the animation is on something like (IsGrounded) it would never make contact with the floor

[grim tiger]

i turned off the Grounded bool but i found this weird capsule position

here is full component

[agile solstice]

Foot IK is a Humanoid Avatar feature
To work with the configuration your rigs must more or less match the humanoid skeleton
Specifically it's the kind of IK that prevents foot sliding, not sure if it also does grounding
The kind of foot IK that you can fully control the target of is different, and offered by the Animation Rigging package separately unrelated to Humanoid Avatars

[grim tiger]

guys wth is that

[shell river]

While playing adjust it in the scene to see if that helps lifting the collider up will lower your character to let it have contact with the ground

[grim tiger]

yep here is the collider up but same issue

the player leaves the capsule and swims in the air

nah unity has impossible issues

can somebody help? im fed up tryna fix this for 2 straight hours

[terse gust]

your structure isn't good, your model should be a child of a parent ("Player"), the player object should have character controller, scripts etc everything, Secondly you have apply root motion enabled which should be disabled when using character controller

[agile solstice]

Root motion works with character controller component, but only if the Avatar is correctly set up for it and the animation clips support it

It's simpler to use clips that don't have root motion, and to place the animator as a child of the character controller, at least before you understand how all those are meant to work together

[agile solstice]

Root rotation (and transform values of the bones in general) are controlled by the animation clips
Mostly it looks like the default un-animated pose of your rig has different transforms than the animation clips you're playing on it

That's why it's helpful to have the animator as a child gameobject

That what way you can apply a transform offset to the animated character relative to the character controller gameobject in the case that the clips have an undesired offset

If the character wanders away from its transform origin in a locomotion clip, that means the clip is made for root motion but you're not using root motion (nor removing it from the clip)

[grim tiger]

Alright i fixed it but faced another problem

I only pressed D

[grim tiger]

fixed it when i put the camera outside the Player Parent

how to put the camera without making him go crazy

[tribal crypt]

It does. The constraint projects the center of mass along a velocity vector. By default the only velocity is gravity (pointing straight down). Simply add to this velocity along the direction you want to move to lean into it.

Another use for this is leaning into headwind. You would lean into a strong gust to compensate

[agile solstice]

That depends on how your character controller processes input, and how you've set up the Cinemachine camera
Because you have one named FreeLook Camera but it's not following the character at all, it seems most likely you've misconfigured it
Not related to animation

[grim tiger]

dang i followed youtube tutorials and failed
What about this bug

[terse gust]

bro you need to learn still, maybe ask AI models to check your code

[terse gust]

[grim tiger]

ai sucks

[agile solstice]

It's likely related to the movement or animation scripts, or both, but the video only shows the symptom
You should verify that the character controller is actually being moved, that it's not just the animation that's reacting to input
Animation, character controller and cinemachine are all separate parts which need to work together, and each of which you need to understand separately

[grim tiger]

hi i fixed this minutes ago but do u know C# enough?

[agile solstice]

I would especially not recommend AI to beginners, as it cannot be trusted to not give misinformation

[agile solstice]

If you have code or character controller issues you should ask in #💻┃code-beginner

[terse gust]

[cold jungle]

I've tried doing many times, and many ways, but I get errors.

My character remains in T-Pose. Here's whats going on.

I'm using Mixamo (humanoid) animations, and my own own custom humanoid avatar/rig to use them.

Rig Error: Copied Avatar Rig Configuration mis-match. Transform hierarchy does not match:
Transform 'CC_Base_Hip' for human bone 'Hips' not found

(Filename: C:\build\output\unity\unity\Modules\AssetPipelineEditor\Public\ModelImporting\ModelImporter.cpp Line: 2693)

[wanton trellis]

Your custom humanoid rig still needs to adhere to the rules unity expects for humanoid rigs

if it isnt properly set up in blender or in whatever software you set the armature up in

it wont work in unity

biggest cause of issues is broken bone chains

[tribal crypt]

Test with a very simple animation.
The animated properties are:
Foot IK position and rotation (L+R)
Hip (only Y-axis)
Support ratio (0-1 range. 0 = shift center of mass above left foot, 1 = right foot, 0.5 = even weight distribution)

I'm not an animator, and only spent around 30 minutes on this walk cycle. I think you could take this concept quite far once you polish the animations.

[agile solstice]

Far from natural but even at this stage it could be used in fun ways!
In a natural walk cycle the center of mass and body parts move with inertia
Hips also tend to rotate around the vertical axis and the shoulders would rotate in the opposite direction to match

[tribal crypt]

Inertia is represented (barring anticipation) by the derivative of the support animation curve.
When the derivative is <0, the right foot is "applying force" towards the left foot, and inversely so for >0

Side note, I feel like the reason this graph is basically a sine wave is due to us being inverted pendulums when we walk

[tribal crypt]

Don't pretend he dont got the greatest gyration in the nation

[agile solstice]

Dangerously groovy

[finite finch]

Hey, i made a snowman in blender with a rig for its body and a hat, which is not body of a snowman so i didnt make it part of a rig but i parented it directly to one of the bones. Also i have multiple hats which i switch on demand.

I made a simple animation where i want my snowman to take his hat into the hand and wave a bit. Animation is done but i cant grab the hat as its not part of the rig. Can i add animation event on specific frame and de-parent the hat from head bone to hand bone for a few frames and then re-parent it back when he puts his hat back on the head ? i know the exact frames

Or is there a better way?

[agile solstice]

Could have a "hat bone" in the rig that whichever hat stays parented to while the animation moves it as any other bone

[finite finch]

ohh, interesting, is that how people normally do? add bones for the outer clothes like hats ?

[agile solstice]

Sure if there isn't a compelling reason why not to

[finite finch]

thx! such idea never even came to my mind!

but no, wait, to what do i parent such hat bone?

[agile solstice]

Head bone usually
Blender has bone constraints for swapping the effective parent on the fly without altering the hierarchy to quickly attach the hat bone to hand

Upon exporting these constraints will be baked into keyframes

If very high accuracy is needed, this method has the drawback that because the hat bone is actually a child of the head, yet the keyframes are moving it along with the hand, the hand and the hat can become slightly disconnected

Because there's always a little bit of keyframe baking inaccuracy that gets amplified down the bone chain

Because of that it may be slightly better to have the hat bone as a child of the root bone instead, and control its parenting purely with the blender constraints

In addition to that unity also has Multi-Parent constraint in the Animation Rigging package which does the same at runtime
That'll fix the bone into any other bone with perfect accuracy on command
But usually it's a bit overkill

[finite finch]

so its done in blender? not unity ?

[finite finch]

actually nvm, i think i should simply learn about constraints, never heard about them, already see that its something powerful that i need exactly for my situation

[agile solstice]

Yes
Both blender and Unity have constraints for doing technically the same thing
The difference is that blender's constraints resolve into static keyframes upon export, while unity's constraints are dynamic at runtime

Unity's constraints are less advanced, cost runtime processing power to keep running and you have to debug them more to make sure they work in all situations (whilst in blender you can just tweak the clip) so you'd only use the runtime constraints if the motion can't be done with pre-baked constraints

[modest moat]

Hey, I'm using a 9 animation blend tree for movement. Very typical setup. Annoyingly though, my test animations for walking are jittering when I change walking direction. I looked in the animator and it seems to be flickering between animation clips. Anyone else encountered this issue? This is particularly noticeable for me because the root of my character's armature is their pelvis which rotates during walk animations so it looks like my character is shaking their ahh 😭

[agile solstice]

Are the blend tree's parameters themselves jittering? Or are they smooth but the clips jitter during blending

A video showing these side by side would help

[modest moat]

I'll try to get you one!

Just a brief delay because I have to do a thin

[modest moat]

it seems to be flickering between clips, especially when I hold left or right

[sterile vine]

the parameters seem to be jittering quite a bit, how are you calculating them?

[modest moat]

Probably not the right way! haha. I can switch between the parameters just being based on the moveinput on the movement controller or relative transform of my physics based movement aparatus. but they both have the same issue

And yes the parameters are jittering intensly and idk how to fix.

[sterile vine]

how are you calculating them?

[modest moat]

I can switch between the parameters just being based on the moveinput on the movement controller or relative transform of my physics based movement apparatus.

Both of these methods have the same problem so rather than fixing these methods I'm open to moving on to another method.

[sterile vine]

that doesn't actually give us info about what's going on behind the scenes... show the actual code

using the moveinput or a resulting local velocity are some valid approaches, but it sounds like you're doing something wrong with them

maybe you're using the value with deltaTime multiplied in?

[modest moat]

I'm not a coder, but this is the script. it's really shit though.

[sterile vine]

quite hard to read, but yeah that impulse one is frame-rate dependant

but the moveinput one should be consistent - are you using a controller? if so, have you tried checking for it jittering?

(but yes, for future reference please share it properly so it's easier to read)

[modest moat]

I'm ditching the entire script 😭 I'm going to try using rigidbody to measure velocity z and x. This would be a lot easier with a character controller component but the plan for this game is for it to be highly procedural and physics based to a physics based character controller is kinda what I made but its causing tons of issues.

[sterile vine]

that probably wouldn't fix this issue

man i'm trying to help here but i kinda can't if you don't answer any of my questions instead saying you're just going to rewrite it

a rewrite isn't magically going to solve an issue that we don't even know the root cause of yet

[modest moat]

The cause is the jittering, and the jittering is caused because I've not properly managed the rigidbody, and by extension relative transforms of the player controller's movement based on engine physics. Thanks to your input I've diagnosed the issue and now need to focus on the character controller's shoddy method of managing these things.

[sterile vine]

the jittering is not related to the rigidbody if you're using the movement input

ah well, you are using the rotation

you haven't given any info as to how that's managed though, so gl if you don't want help i guess

[slow forge]

Hi everyone. I know this is a little backwards but ill try to explain as best as i can

I have a collectible in a 2d game. It has a parent class called collectible and a child class called Gem.

    if(collision.gameObject.CompareTag("Player"))
    {
        OnCollect();
    }

I use this to collect the gem and everything works.

Now I need to make the gem pop out of a chest.

            Vector2 force = new Vector2(Random.Range(-1f, 1f), 1.5f).normalized * launchForce;
            gemRb.AddForce(force, ForceMode2D.Impulse);

I used this to make them pop out. Made a parent object for my gem prefab and attached a rigidbody. But now my OnCollect animation goes all over the place when i collect the gem cuz its location is different so it does a rotating movement

TLDR; How can i keep my animator local space coordinates while moving an object

[tribal crypt]

First pass of procedural walk animations.
Only things animated here are the locations of the nodes (4 yellow spheres on the ground)
As well as the hip height near the end (to be fixed later)

Things I plan on adding:

• Acceleration (leaning into sudden turns)
• Hip height displacement (For when legs stretch too far)
• Secondary motion: Foot, hip and torso rotation.
• Complementary movement script, controlling with WASD.

I hired an artist to make the model and do the rigging for me.
Is there an easy way I can do this myself, or is there something specific I should say to the artist?

I'm trying to use Mixamo animations that I was using on a placeholder model on another model with a humanoid custom rig/avatar.
This model was made by an artist with far more experience than me.
I've tried doing many times, and many ways, but I get errors.

My character remains in T-Pose. Here's whats going on.

I'm using Mixamo (humanoid) animations, and my own own custom humanoid avatar/rig to use them.

Rig Error: Copied Avatar Rig Configuration mis-match. Transform hierarchy does not match:
Transform 'CC_Base_Hip' for human bone 'Hips' not found

(Filename: C:\build\output\unity\unity\Modules\AssetPipelineEditor\Public\ModelImporting\ModelImporter.cpp Line: 2693)
.
I've attached screenshots of the rig in blender and the model.

I've been told the armature has been set up wrong, but I'm a programmer, and have no idea what may be wrong or how to fix it.

Does anyone here see anything that may be suspicious?

I don't know what tool was used to make this.

[cold jungle]

Could this bone (pelvis) be breaking things?

[wanton trellis]

Your rig isnt properly set up in blender

Thats almost certainly the cause

Youre either going to have to do it manually with the help of some tutorials or have the artist do it for you if they know how it works

Basically the rig needs to follow some specific requirements to work properly as humanoid in unity

https://docs.unity3d.com/540/Documentation/Manual/BlenderAndRigify.html

This is for rigify but the "rules" should apply to your own rig as well

[odd kiln]

hello everyone. I'm new to unity and I'm experimenting with animations for the first time. I'm currently experiencing a problem where my character's backward animation freezes as soon I go forward and vise versa. I'm probably making a rookie mistake, but I can't seem to find a solution in the docs.

[arctic remnant]

is there a way to add IK to seperated game objects (2d sprites in this case)

[agile solstice]

IK tends to require a hierarchical relationship
Physical separation / offset should not matter, but depends on the type of constraint how it handles offsets

[agile solstice]

A mistake in how you've implemented your animator transitions / parameters/ how you're setting them
Should record a video showing the animator and character side by side in action during play mode with parameters tab visible, then also click through transitions with their settings visible

[tribal crypt]

Here's an update on the rig, in case you are interested

Hip rotation is next!

[onyx leaf]

Hello, I'm a unity dev just getting started; I have a long history in 2D animation, but I'm trying to learn 3D and programming at the same time here.

I'm having an issue figuring out the blend tree and it's hard to say where the issue is, but I assume it's an animation issue.

Basically my character is "vibrating" while they're moving. I'm just using a 1D Blend Tree to start, and currently have only an Idle and Walk (planning on having more movement types of course). My parameter is just called Speed, grabbing the linearVelocity of the rigidbody and it looks like it goes kind of haywire while I'm testing the movement.

Any direction on how I can go about solving this?

[gray bronze]

The new model looks like a character creator 3+ rig. Have you tried simply using the animator controller directly on this new model? So for the animations, don’t pick “copy from other avatar”. Just create from the one the animations shipped with.

[arctic remnant]

Does Ik require rigging with bones? my sprites on the sheet are separate.

[halcyon moth]

Hello, I'm currently having a problem with the NPC, where they are stuck in the idle animation and won't use the other animation I prepared for them. Do they need a code to make it work? since I'm currently testing my project game for quite some time

[uncut salmon]

How are you actually making the animations change?

[halcyon moth]

transitioning from Idle->Start_Walking->Walking->StopWalking->It will come back to Idle

[uncut salmon]

Okay and how are you calling these transitions?

[halcyon moth]

I dont know, sorry I'm kinda new to animation and Im currently been watching tutorials in youtube on how it works

[uncut salmon]

Unity can't automatically just know what your intentions are with these. There is IsMoving bools handling your transitions which you need to actually define in code.

However, for movement/blending, you probably want to use a blendtree, not hardcoded transitions like this. Something you can also check out a tutorial for.

[agile solstice]

No, IK moves transforms while sprites can be attached to the transforms either individually or via skinned rigging

[agile solstice]

Because Has Exit Time is enabled, the transition only occurs at Exit Time (under Settings field there) relative to the source state
That means if your walking animation is 10 seconds long, the transition to walk only occurs if the idle is at the very end as that's where the second clip starts on the transition timeline

If Has Exit Time is not enaled, the exit time will be a delay from the point the transition condition is met

So what you want to do is disable Has Exit Time from the transitions and click and drag this blue rectangle between the arrows all the way to the left to get rid of the delay

If you want a transition to occur automatically, you can remove conditions and leave Has Exit Time on
Then the transition occurs after the specified delay has passed / after Exit Time
I recommend reading this stuff in the docs

[placid anvil]

Hi everyone!
Can someone help me? I'm having trouble with the animator (Unity 6) for the enemy in my 2D game. I've checked all the sprints, I've validated it to see if it's correct within the Blend Tree animator, it's reaching the animation, the blue bar appears in the animator box, I've checked the motions, I've checked the controller, but nothing... it doesn't work... what do I do? I've already made another clip for testing, please someone contact me privately to help me?

Problem:
The animations, in this case the sprints, are not waiting. I've already validated the clips, redone the controller, validated if it was pulling the sprints correctly, validated the controller if it's in the correct element field, but it still doesn't work. In Blend Tree, the bar indicating that the animation is playing is working...

[quasi fable]

You should show the details of your problem. Show what you mean by "the sprints". Show the state machine, the transitions, etc.

[placid anvil]

Actually, I meant sprites. I'll send screenshots of the controller; the motions are also configured.

If you look at the screenshots, you can see that it's correct... I don't understand why it's not creating the frames...

[placid anvil]

Can I call you without specifying what's in it?

[quasi fable]

right so what are you expecting to happen here that is going wrong? I'm not sure what you're trying to show exactly

[placid anvil]

My problem is that even with the animator configured, all the clips and motions aren't playing the animations.

[onyx leaf]

Have you had any success with the animator in the past? Do you have a character that can simply animate when walking? I am also a beginner, but I've definitely gotten the animator to work with sprite animation before.

[fervent canopy]

hi, i'm following the "Adventure game tutorial" on unity learn and a bit confused about the animation tool, where the tutorial says

The Flip X property controls whether the sprite is horizontally flipped for a given frame.

6. Select the first frame of the animation in the timeline (Frame 0), then enable Sprite Renderer.Flip X.

7. Select the fourth frame and check that Sprite Renderer.Flip X is enabled for the frame.

This will ensure that the sprite stays flipped for the entire animation. The diamond icons aligned with the Sprite Renderer.Flip X property at frames 0 and 4 indicate that there is a change in the value of the property at that frame.

I'm confused what those diamond icons are on the right for each frame, I guess the 2nd one on frame 0 is supposed to indicate the change of the flip X property? but you only have to apply it for the first frame?

why do they mention to flip it for 4th frame?

[viral hedge]

Hey, can anyone tell me how to import the fbx file of a cloth animation from Blender to Unity?

Problem Statement: The Alembic file is working perfectly. In the fbx file, model and animations are getting downloaded, but animations are not working in the scene, they are shown working in the animator, but in scene the cloth is not at all moving.

Can someone please let me know what is happening?

[gray bronze]

Did you install the Unity alembic package

[fallen yew]

Its just so from beginning to end, the sprite flip is the same value. Good habit for animation if you want things to loop nicely-- otherwise you may end up with jumps.

Also when you have animation blending, itll try interpolate from the last point iirc, with someting like a sprite flip you want that enable the whole way.

[thorny plinth]

hello, so i tried to export 3d animation into unity the first time, and i realized things dont move if they were not initially from the metarig (made extra clothing bones and parented to the rig instead of the skeleton) what would the work around be for this??? do i have to reanimate it or do i have to somewhat add the bones to the metarig???

would it be alright if i just add the added bones onto the metarig?

[agile solstice]

Yes
If you animate the Metarig directly it's just a typical rig, no Rigify features included
So if you aren't generating a Rigify rig from the Metarig it doesn't matter how you modify it

[thorny plinth]

i animated it with the generated rig! i have somehow got my extra bones that r tails and hats working in unity, but my clothing does not :(

here is the breakdown of my extra bones that i parented to the rig, idk but im assuming its bc the cape is a seperate mesh so it doesnt get effected by the rig in unity, but im not sure how i would fix that

oh that wouldnt make sense either since the hats r tails r also seperate.. uggughgg

[agile solstice]

If extra bones are added to the Metarig, you just need to define a rig type and it'll be generated along with the other bones
https://docs.blender.org/manual/en/latest/addons/rigging/rigify/rig_types/index.html
Basic.super_copy for example, but some are better suited for specific purposes, like the tail ones

Note however that Rigify doesn't technically support exporting out of blender, unless converted using a plugin like Game Rig Tools
Rigify's complicated hierarchy and constraints don't normally carry over on export, so glitching can appear in Unity

[thorny plinth]

ahhh

okok ill give it a read, thank you for your insights!

[earnest kestrel]

I had a placeholder character model + avatar and a quite complicated mecanim graph with a bunch of animations that all worked fine (video 1)

I then changed my model + avatar to something more fitting, and for some reason the character has this enormous gap between his legs.
How can I fix this?

[wanton trellis]

Well its either because of the characters rest pose in the humanoid avatar or the footik is not turned on

[sullen wyvern]

Anyone got an idea why the animations dont match?

Right leg deviates from the blender keyframes and strethces like that in unity

only happens in the late part of the animation

[wanton trellis]

You have import warnings in unity

are you sure they might not be related to your issue

[sullen wyvern]

Didnt notice that, let me have a look

U dibt think so, since the other animations work well

[wanton trellis]

what do the warnings say

[sullen wyvern]

Self itersection polygon x2

and it has been disgarded

wait I found it now finally Xd

No import issues now, but issue persist

[wanton trellis]

did you apply all transforms to your armature and model in blender?

is the bone influence set to 4 per vertex in blender?

[sullen wyvern]

All transforms are applied

And I couldnt tell you about the second, I dont know what that is even 🙂

The foot ik for the foot, is at the correct position

[wanton trellis]

Is that something you added in unity or did you export that with the rig?

[sullen wyvern]

Its directly from blender with rigify

It's only that "foot" for the last 15-20 frames that it doesnt follow correct, and all other animations work in unity apart from this one, and all work in blender

[wanton trellis]

Did you follow the rigify to unity set up guide?

Because im pretty sure even for generics you cant just import it directly without some tweeks inside of blender

not saying its the definitive cause of your issues, but it could be

[wanton trellis]

have you tried rexporting that animation as a skinless fbx again? Maybe tweek the value of the last keyframe for what foot slightly

[sullen wyvern]

From my experience its fine, ive done unity ik on rigs with no "unity" rig. I've done it on humanoids atleast

[sullen wyvern]

I could see if that make a difference, but looking in unity

Let me show you

both on last keyframe now

seems like the issue is or atleast the first point the def-foot

[wanton trellis]

Hmmm i would suggest you try it, it could be a very rare exporting issue

If that doesnt solve it then its most likely something to do with the rig

[sullen wyvern]

So just export rig with no mesh?

[wanton trellis]

just that particular animation yeah with an adjusted last keyframe

[sullen wyvern]

I will try

I solved it

Kind of atleast Xd

I make sure to reset everything at key 0, and then I removed some keyframes from some "internal" bones and redide some of the foot movement

now both legs work, I think the movment on the thigh bone in xyz space cause the issue

[onyx leaf]

https://youtu.be/FDsuBoWpGd0
I'm having an issue keeping my speed constant, which is causing some really annoying jittering to the animation and a "lurching" to the movement.

I've been trying to diagnose this problem for a week, revising large sections of my character controller and I'm pretty frustrated with how movement feels right now.

[wanton trellis]

I think the issue might be how youre getting the speed as a parameter for your animator

can you show us that code

[onyx leaf]

Sure! Gimme a sec.

[wanton trellis]

Ideally you would use "gaits" for this rather than a floating speed value

So a gait basically sets your animators speed parameter to a fixed amount, but the gaits change between velocity values of your character

[onyx leaf]

It already sounds like you might know what I need to learn.

[wanton trellis]

so small changes in your characters speed wont change the entire gait causing the blend tree to shift

[onyx leaf]

Basically my code says _animator.SetFloat("Speed", rb.linearVelocity.magnitude);

which immediately sounds like what you're telling me not to do

[wanton trellis]

Walk 1 – 2
Run 2 – 5
Sprint 5 – 10

Imagine it like this

as an example

[onyx leaf]

Alright, so basically I need to decouple it.

[wanton trellis]

to test it out you can use like 3 if statements

[onyx leaf]

I already have a state engine ready to go

so I should probably just send an Int to the animator rather than the speed

[wanton trellis]

perfect that makes it better

try something like this

gimme a sec

[onyx leaf]

Oh sure! I still have questions.

[wanton trellis]

float SpeedParam = 0f;
switch(currentState)
{
    case MovementState.still:
        SpeedParam = 0f;
        break;
    case MovementState.walking:
        SpeedParam = 1f;
        break;
    case MovementState.running:
        SpeedParam = 2f;
        break;
    case MovementState.sprinting:
        SpeedParam = 3f;
        break;
}
animator.SetFloat("Speed", SpeedParam);

[onyx leaf]

Oooh

That makes a lot of sense. Thanks! I'll try this right away.

I have some weirdness with my state handling as well. I'm not sure where in my Input System I need to change the state to my default speed (running).

[onyx leaf]

This feels like brute forcing it but I got it to look right

[gray talon]

So I have a question, I've been working on an avatar model for a game that requires complex avatar customization but also complex animation system... and I noticed that blender exports 'combine' NLA strips as part of the animations that have the name of that NLA strip, but they're combined with the underlying base NLA strips that are set as 'replace' for that armature. I have two armatures, one for facial expression and overall blendshape manipulation, relying on drivers, and another one that's heavily bone constrain based. They both work together to allow me to combine two separate level of animation into multiple animation combinations. But that export issue is having me stumped.

Is there a way to have the fbx export each animation as a unique animation, regardless of its state in blender, so that I can actually easily preview the animation in blender, without worrying how it's going to export for the use in unity?

I also don't want to export ALL animations that are in the .blend file, just the ones selected in the NLA strip, but without combining

it's heavily annoying me

[agile solstice]

Use action editor instead of NLA editor, and only one Armature if possible
That makes it so each action simply maps to one exported clip
But in this case multiple armatures / objects get a duplicate of the clip on export
(Unless the way newer Blender versions allow linked action data skip this duplication, haven't tried it)
I've always avoided the NLA editor entirely, so I can't say if there's a better method found within it, or if it could be used to your advantage together with action editor
I wouldn't worry about excess clips, as they can be stripped out in Unity when importing
(Or deleted from Blender in file view before export, then undo that deletion after, which is probably also not the best way but didn't have the need to find a better one
Action editor supposedly exports only actions marked as fake user or which were pushed to NLA editor but those details seemed also a bit too tedious to learn so not sure)

Combining the actions in blender the right way before exporting seems like a simple solution to the first problem

Differentiating them with naming convention may skip the need to pick only them for exporting

[gray talon]

I'm developing a somewhat dynamic animation system so I'd rather combine them in unity, which is why I have to keep them separate

[agile solstice]

Ah, then I seem to misunderstand the first issue

You want to output them as separate but preserve their timing relative to each other in some way?

Or is the trouble exporting them as separate at all

[gray talon]

blender NLA is good for preview of how I want the anims to look in unity, I can easily set multiple animations to base and overlay/blend
So I want to export only the animations from selected NLA strips, but each animation separate, without having to get rid of the excess every single time 😐

I guess I'll just have to have separate blender files for only animation export

[agile solstice]

The animations themselves are Actions, which afaik use the fake user flag both for being exported and saved which certainly isn't convenient in your case or in general
I recommend naming conventions
There should be no harm in exporting all, as long as you have an easy way to ignore the unneeded ones

Builds will strip unused assets, including animation clips

[gray talon]

I am using a naming convention luckily so I know what is a facial animation, what's a walkstyle, what's an idle etc etc

Thank you, I'll live with this minor inconvenience

Untill blender maybe fixes it, then I'd be happy and sated

[glad oasis]

Is there any resources for network animations? Im making a game with NPCs but the animations arent being sent to the clients of the game that arent the owner

[remote frigate]

trying to figure out how to extract this to edit on since it's read only

[steep cairn]

open the model file (little arrow next to it) and select the animations, then copy - paste them

[remote frigate]

Thank I just left clicked it and ctrl D and that worked you just saved me a headache

[remote frigate]

when I add the event I dont see where it is saved and when I go back to the same frame its not there anymore

[agile solstice]

Hard to see the frames at all when your animation window is not wide enough

[remote frigate]

I think your right

forgot you can expand it xD

thanks mate

[ivory star]

Hey, guys! You know I have a question. There is a keypad puzzle that I have made for my game, and I was wondering how I am supposed to make my keypad buttons to animate like being pressed and released.

What I have created right now is an animator controller component on all of my buttons and attach a single keypad button animator controller to each component.

The problem is that when I am trying to animate a button and then another button because they have the same animator the one overwrites the transform position of the other one.

Is there a way somehow to prevent this from happening? I know there are override controllers but the logic is the same I dont have to create different animation clips to my buttons, they will have the same animation.

I am thinking basically to add an empty object on each buttons so that I will be able to animate the child not the parent/root object

I think that will fix it

[agile solstice]

Yes
This is the same as giving the animated button an empty parent transform
When an animator overrides its own transform position, that override will be relative to its parent transform, or the scene if there's no parent

[ivory star]

basically I did something like this. My buttons which have mesh renderer component, script components etc I put them under a root empty object in which empty object I have the animator component

and now it fixed I dont see them both overwrite each other when pressing play mode

[true glen]

Hey Im an absolute animation noob, how can I fix this issue that my transitions look wrong? I dont want them to be instant, that looks weird as well, but my player could for example be running forward, stopping, and running backward. With my current settings that will keep running forward for .25s, then idle for .25s, and then run backwards, even though the idle time might just be .1s before pressing another direction, this feels so weird and IDK where to even begin fixing this

[sterile vine]

do you have exit time set on the transitions

it sounds like you're describing the effect of exit time

[true glen]

I dont have exit time enable

Pretty much how they all look

[sterile vine]

probably that fixed duration, eh

and the transition duration

[true glen]

As I said I dont want the transition to be instant because that looks off as well

[sterile vine]

hm, might be able to use the interruption source setting

i'm not super familiar with these transition settings though, so this is about the limit of my knowledge

[small sentinel]

How would i go about disabling the animating process for arms? Everything seems setup, but the arms are still being animated from the base layer animation.

[wanton trellis]

Does the base layer include arm animations?

[small sentinel]

yes

[wanton trellis]

And the Arms avatar is set up correctly?

[small sentinel]

Seems so, the base layer animations seems to work fine

ok, it wasnt set lol

let me try haha

[small sentinel]

ok, still the same, even if i import the avatar and toggle on all the transforms for the mask

[agile solstice]

It is the Exit Time that causes there to be a delay
It is greyed out when Has Exit Time is off (and it should be off) but you can also click and drag the blue rectangular area at the top of the transition timeline all the way to the left so it is timed to occur without waiting

[small sentinel]

so apparently if theres no keyframes in the clip, unity wont animate the layer

not exactly what i need, but i guess ok

[brazen mural]

I want to have dust pop up from feet if running on sand, none if running on tile, etc. Is this something where I would need to make another empty child with it's own animator connected and just like enable it when on sand, or is this something I can do all in one animator? Does one animator correspond to only one spriterenderer?

[wanton trellis]

I dont think you would use animators for anything here

[brazen mural]

Why not?

[wanton trellis]

Sounds like you just need to instantiate some particle effects and check for surface materials

Check if your character is moving, then check what material they are moving on, then use particle effects to create the effect of kicking up dust

[brazen mural]

Ah, okay. What about for things like footsteps?

[wanton trellis]

like the sfx?

same thing

check if they are moving, what they are moving off

[brazen mural]

Sorry, Footprints

Leaving footprints

[wanton trellis]

oh, you could use decals

but once again same exact principle

[brazen mural]

How do I make it line up with the correct foot in that case, though?

I feel like I'd have better control with an animator

[wanton trellis]

Well

the real answer here would be... you dont

or rather you dont have to

[brazen mural]

this is for 2d also

[wanton trellis]

oh?

like a top down 2d game?

[brazen mural]

yes

Particle effects may work better for the cloud effects that I want, but I'm not sure

I want to have more control with what is outputted

[wanton trellis]

for a top down 2d game i woul say that the level of precision matters even less

Honestly if i were you i would start with the particles first

figure that out then see what you want to do for the footprints

[brazen mural]

It's less about precision per se than like having it be pretty

I feel like that may be harder with particle system but I haven't looked into it a super ton

[wanton trellis]

There are few resources online

Look up "Unity 2d particles" im sure some official unity guides will pop up

[brazen mural]

Thank you, that's a good place to start

[odd kiln]

Hello everyone.

I have a little problem. I'm working with a character using root motion and a 2d freeform blend tree. Most directions are working fine, but at around -.91 -.41 (other side also) creates a really awkward movement. The character is bouncing, speed is low, and the legs are crossing strangely. I'm happy share a clip and pics with the relevant info.

[agile solstice]

Animators can override any component in the gameobject hierarchy, not just one sprite renderer
If you use a child gameobject for these, they would remain attached to the parent gameobject in motion
So it wouldn't be very useful to keep the effects attached by parenting
You can animate a child transform position along with your sprite animation clips, then instantiate independent dust or footprint gameobjects at the child transform positions
Animation events can be used to time them to motion

[little path]

I have an animation from Mixamo that is supposed to put the character on the floor, but when I use the animation in Unity, they're hovering above the ground. The start position is correct, the feet are on the ground, at the pivot, but when they fall forward, they just kind of twist in midair and bring their feet up to the new resting position.

I uploaded the model to Mixamo to get the animation from. The model has a Humanoid Avatar, and the animation clip is set to use that avatar (Generating its own humanoid avatar seems to have no effect, same result). The animator is not using root motion. I've tried out all sorts of combinations of the "Based Upon" dropdowns for the Root Transform settings in the animation.

[wanton trellis]

Iirc this is an increasingly common issue

ive seen like 10 different people with this exact issue here

and i dont even remember if anyone found a fix

[little path]

[wanton trellis]

try downloading the animation without the skin

and see if that has any effect

[little path]

It is without the skin

Only the main idle pose the avatar was generated from has the skin, all of the other animations were downloaded without.

[wanton trellis]

how outré

[wanton trellis]

do you have any colliders or anything set up on the gameobject?

[little path]

Yes, but they're on a sibling object of the model, the animations have no effect on the colliders

And the displacement is on the model specifically, it happens even when viewing it in isolation in prefab view, playing it from the Animation tab

[brazen mural]

Oh this is really helpful, thank you

[gray talon]

For people who want to export separate multiple animations, just keep the naming convention of the NLA strips different (if two or more NLA strips have the same name, they'll export as the same animation, often bugged).
And then if it's still bugging out, just star the animations that you want to export. Export with "All Actions" unchecked, since this will export unwanted animations.

If you want to combine the animations, as in combine multiple selected NLA strips into one exported animation, still make sure to star the NLA strips, but in FBX exporter, unselect both "All Actions" and "NLA strips" and the FBX exporter will export all active/playing animations in the scene as one animation. This is also very useful if you have a hybrid or multiple armatures.

[agile solstice]

Good to know
With multiple armatures I assume they can share a clip in blender, but still will get separate instances of the clips when imported to unity?

Meaning they will have to run on separate animators

[summer basin]

Hello, I have a problem with importing the shape keys the eyes from my charachter to unity, i tryed everything out in youtube and gbt, could someone helping me out?

[gray talon]

No. The other way around actually

By default, the animations with same name in NLA editor or the ones exported as the 'scene' animation (both 'NLA Strips and 'All Actions' options off) will be combined into one animation, even with separate armatures.

You can keep them separate, by not naming them the same in the NLA editor and exporting without 'All Actions' option. But you can still combine them in the animator. The success depends on how 'separate' your armatures are. My secondary armature is for blendshape animation (facial and morphs) powered by drivers. And my primary is for deformation animation. So they never touch so I can easily use them in the same animator without much issue.

[gray talon]

Exporting as 'All Actions' is buggy with multiple armatures. It will often export clips that are completely botched.
When I had both it and NLA strips on it would export the animations I want from the NLA strip + a few other botched animations... And NLA strip animation exports are also buggy with multiple armatures, so you need to 'star' the nla strip animations you wanna export instead.

I doubt some of these would be issues if I'd have only one armature. But I need to keep my armatures separate, since if they were packed into a one armature, the blendshape driver one ends up affected by the deformation one and vice versa, and I get artefacts in movement of both.
It's probably a rigging issue but I spent too much time trying to resolve it without success so it's just not worth it.

[patent mountain]

Have transforms on the character feet and a Event on the animation that calls code to spawn a decal

[brazen mural]

This is a dumb question but everyone is mentioning decal, is this any different from like a sprite and if not, what is the difference

[wanton trellis]

a Sprite is a kind of 2D graphic object

think of it as just an image really

But a decal is material that you project onto your 3d enviroment

[brazen mural]

Is it the same if I;m in 2d

Where do you put controllers for your bones for arms IK. Is it better to have a controller for a hand bone created on the previous bone in the chain (& put the constraint on the hand) or extrude the controller from the hand, and keep the constraint on the hand?

[agile solstice]

That's something to ask in a blender discord

[midnight adder]

Yes yet the setup would be the same in 3ds as well, Im asking here if anyone understands the correct workflow

[agile solstice]

3ds is not Unity either

[midnight adder]

What?

I have played around with rig builders and IK constraints in Unity before, you are saying there are no univeral similarities in the workflow?

[ripe valve]

soooo I am not really good with animation but i desighned this little character, but each time when i make a animation it just looks very chopy and nothing like i want, kinda in hollow knight style

[wanton trellis]

This doesnt sound much like a unity question

and more like a question regarding animation itself

[ripe valve]

Oh woops

[fallen yew]

choppy because of wonky animation or something wrong with your spritesheets?

also as an animation tip, animate the character without the cloak first, make that look good, and then figure out how the cloak should move afterwards. break up you animation problems into managable pieces

[gray talon]

Same goes with sword swinging animation. Your character has a cerain weight you want to display in their animation when they move or jump. But with a sword that big, the movement should be slower when the character is hitting something. The animation should feel heavier.
I suggest looking into 12 principles of animation. They're the best starting point for this kind of thing.

[viral hedge]

Yes. Alembic is working, but I want it in FBX

[agile solstice]

Alembic is required for exporting simulations
FBX only supports armature deformation and blend shapes

[odd kiln]

Hello everyone. I could use some advice on blend trees and 8 directional movement. My character seems to be playing jump rope at certain coordinates.

Any advice would be appreciated. This is a root motion setup, where the character's speed and direction are driven by the animation. My character seems to be playing jump rope between the back run and diagonal back run. on both sides I managed to somewhat solve the problem at certain coordinates previously by just duplicating animations in the coordinates in question, but I'm not sure if it's an acceptable solution since I'm new. I've made all of the animations start when the left foot hits the ground using offset. IK is on, and the layer has IK passing. if I turn either of them off, it all goes haywire.

[nimble apex]

Hello all, I have:
a game object image
i added an animator to it

I then have five animator controllers, i swap them at runtime with code logic.

However, it only shows the first frame of the animation and doesn't play until i go into the animation window and selct play.

I have the code like thiss:
// Wait one frame for the animator controller to initialize
yield return new WaitForFixedUpdate();

    if (anim != null)
    {
        anim.speed = 1f;
      //  anim.Play("Banter");
    }

This is after i assign the controller with runtimeanimator controller

Anyone messed with switching them at runtime before?

[agile solstice]

It would help to show the two animations separately
It looks like they might have the opposite offset
But also seems likely that those two motions can't be blended because you cannot make a perfect "circle" of strafing animations that would all blend with the adjacent motion, best I can tell

[agile solstice]

Yes, but I haven't had this kind of issue
Using the Animation window always overrides the animator component behavior so using that isn't indicative of much
You'd rather check out what's happening on the Animator window side
It seems you're doing a few more things than just swapping the controller though, so maybe you should simplify your setup for the test

[astral raven]

I dont know where to ask this so I'll ask here. Im making a game in unity and rn and Im making a door in blender, will it be possible in unity to move the door handle alone without the door or do I have to make the handle a separate model?

[gusty garnet]

in blender you seperate these meshes so that they are 2 objects, then in unity you can do whatever

you dont need two different models, to say

[astral raven]

so if the door or the handle has more then 1 object to it then I need to join those?

so that they're the same object?

[gusty garnet]

you dont join them

if you join the meshes unity will handle it as a single mesh

[astral raven]

yeah I meant for example here, I didnt mean to join the door and the handle, I meant that if the handle was made with more than 1 object then I would join those

so that the handle is a single object

I of course still need to make it but

[gusty garnet]

yeah you can join the meshes inside of your objects of course

but keep handle and door seperately

[astral raven]

alright thanks

[gusty garnet]

best thing is just to test things out

[astral raven]

does moving the objects in unity have to be done through code or through animation?

or can it be done with both?

[gusty garnet]

it is up to you but for something simple like that definetely animation

[astral raven]

alright

[eternal lantern]

Hello dear unity animator !
i just realised that i've made all my animation on the DragonBoss instead of the GameObject. Everytime i tried to move everything it basically destroyed all i did so... How can i solve this issue please ? Thanks !

*i tried renamming "DragonBoss" in "GameObject" but... Let's say unity told me "no."

[agile solstice]

What do you mean by "tried to move everything", and why specifically do you want to make the animations on the GameObject

Usually you'd want animations to be lower in the hierarchy, not higher

[eternal lantern]

Just for organisation, i've put some animation in DragonBoss and some other in GameObject so everything is a mess and is hard to make functionnal.. (like the particle not rotating with the dragon so i have to put them in a very unpleasant spot)

So i need every animation frame to be on GameObject which is made for animation but i don't know how 👍

[agile solstice]

So do you have two animators with different animations in the hierarchy?

[eternal lantern]

Wait no you're right i meant putting everything on DragonBoss not GameObject* !!!

I dont have animator 😅 because i use a custom made syste but yeah, in my animation (keyframe), some are in GameOBject, some are in DragonBoss !

[agile solstice]

What kind of system? That seems like a relevant detail for the question

[eternal lantern]

Right, a animationSystem !
But i do have a Animator, sorry ! 😅

[agile solstice]

I know you can change keyframed property paths by editing the file in an external text/code editor, but never heard of combining keyframed properties from two entirely separate clips
May be better option to just re-do them

[eternal lantern]

:'( it took mes ages to do it, im afraid of losing them..

[wanton trellis]

This is why you should never animate inside of unity

Always use something like blender and simply export your animations

[eternal lantern]

Oh, i understand now..

[thorny plinth]

hello, does anyone know why the head is jiggly and behaves different when imported into unity?

[agile solstice]

Could be due to curve resampling, or keyframe compression
If it's normal Rigify rather than GameRig or similar that can also change how the deformation looks, but shouldn't affect keyframe timing or interpolation

[thorny plinth]

im using rigify, ill try to key every single head bone, do u think that will help?

[eternal lantern]

Is the Unity animator so bad ?

[wanton trellis]

yes

its not designed to actually create animations, at most its used to tweak certain things and add animation events

[agile solstice]

Doesn't hurt to try

[thorny plinth]

ok! thank u 🫡

[eternal lantern]

Oooh okay didnt knew that... Thanks

[fallen yew]

when you say 'Destroyed' do you mean all the keyframes just go yellow? if so, that is fixable. double click the names in the animator, and fix the paths to be correct.

I made a little tool for this but its not ready to be released just yet, but I can DM it to you if you were interested

[eternal lantern]

Yes that's the issue ! Nice.
I'd love to test your tools but im not allowed to import plugins on my project because it is an evaluation ☝️

[lunar bane]

Hey everyone,

Currently trying to solve an issue with an animator variable not updating from an animation. Each of the ear twitch animations "P - Ear Twitch x" are supposed to update their version of "Proxy/Twitch/x" on so it can trigger an animation in another layer. However, when the proxy animation is triggered it is not updating the correct variable. As an experiment, I put the animations in a loop with the reset animation "P - Ear Twitch None" in the base layer of this animator controller under the same transition parameters. For some reason, it is working correctly there, but not in the Twitch Setup layer. Does anyone know why this may be happening?

Nevermind, for some reason, the weighting for the layer had gotten set to zero. I figured it out.

[agile solstice]

That missing/yellow issue is what I was referring to when talking about editing the keyframed property paths directly
Notepad++ / any competent IDE works for it
Unlike them Unity editor doesn't support multi-editing the properties, and was clunky otherwise too

[silver scroll]

Good day chat, I'm trying to setup a walking anim for a player model, as well as a idle anim, but it seems like the anim isn't playing for whatever reason. Thanks!

Help Maya Users!
My Soda Monster uses blendshapes driven my a set driven key system on a nurb circle. I keep trying to export my key range with animations baked from frame 30-135.
It exports with no failures, but Unity has import issues and imports an fbx with all of the project frames with no blendshape data.
So I tried baking it directly to the mesh before export and deleting the nurb. Well it woks in Maya, but once again breaks in Unity.
Any help with this nonsense? I feel like I'm missing an export step or something ridiculous.
Note I was able to export one of my animations that directly manipulated the blendshape notes rather than a driver nurb.
I'm exhausted and can privide more context and any console messages tomorrow. thanks.

[agile solstice]

I would use Unity's Animation window to look at the clip frame by frame in the Curves tab to see how the distortion seems to occur over time, and how the animation curves have changed from what they were in Blender

Hello ! My animations used to be on "GameObject" but i want to move them on "Body" now. I've renammed them but now i i have the "missing !" error that i don't know how to fix despite looking online. Can you help me please ? Thanks !

[terse gust]

this is expected

[terse gust]

it is possible to change the key paths

so you need to double click on the key for example, the Body : Position (Missing!) (double click it)

it will show the path

update the path to match the new names etc

and it will work

[eternal lantern]

Thank for the help. Im trying to do it but it only allow me to change the name, not the path, so im kind of... lost 😅

[sterile vine]

you cropped out all the relevant details there

Currently working on an asset that has an in depth blend tree setup. Noticed that the controller itself has blend tree references as children. I think this is really useful and would like to use it in my own work. Does anyone know how to create this kind of structure?

[agile solstice]

I believe they are sub assets, managed with methods such as:
https://docs.unity3d.com/ScriptReference/AssetDatabase.IsSubAsset.html
https://docs.unity3d.com/ScriptReference/AssetDatabase.AddObjectToAsset.html

[atomic ginkgo]

So follow up to this issue.
I was able to successfully bake the animations to my monster shake character using a python script that looped through each blend node.
That successfully allowed me to get these exported to Unity with animation data intact. I can see it in the preview window and it looks great!
However, I'm onto another road block. The animator doesn't seem to want to do anything on my character mesh. I made a generic avatar for the Shake despite him having no bones, and then added the shake animator to the animator component.
I'm a bit lost now with what Unity isn't liking. This enemy character uses blendshapes with the no bones. The vertex information is identical, and the hierarchy should be the same. ShakeRoot->ShakeBodyMain->ShakeStraw
Anyone here ever have a blendshape only animator and character?

Also attaching short animation capture for context of what the character looks like and the animations I'm trying to implement.

[wanton trellis]

so are the animations showing up in the unity animation preview window in the inspector?

I dont think you need an avatar for this at all if it has no bones

just set the rig type to generic and keep avatar definition as none

[atomic ginkgo]

Yeah! That's the frustrating part. They are showing up in the preview window fine with no issues aside from facing the wrong direction.
Let me try generic with no avatar on my object when I get home and see how it behaves.

[chrome cape]

Hi, does anyone know how to activate an aimation after an specific action? (example: I shoot my enemy with diferent guns and they do diferent anymations)

[atomic ginkgo]

Sooo many ways to do something like that. On my scripts for my weapons they each get the enemy object on hit and I tell them what I want them to do.
That's typically what a lot of devs do to transfer damage, hit forces, hit type etc.
Say you shoot your enemy with incendiary rounds. On hit of your ray, you can then get the enemy game object and pass whatever variables you want. You call EnemyHealth.TakeHit(damage, force, ammotype)
Then in your TakeHit function you talk to your enemy animator to do whatever you want. In this case play your bullet hit animation and then maybe a burning animation.

What do people use to do pixel art for a 2-d game? i am very new to this if anyone could answer

[sterile vine]

there's a ton of apps for pixelart, typically the choice is just preference

piskel is a free online one

[atomic ginkgo]

After a lot of research and headaches I managed to get the Monster Shake into the Unity engine.
It was missing a "Skinned Mesh" component that allowed the blendshapes to manipulate the mesh. The solution was to simply skin the mesh to a few bones in Maya and reimport. It took me 3 days and a lot of troubleshooting, but I did it.

[astral raven]

idk where to ask so Im asking here, why does it give those warnings and what do they mean?

[fallen yew]

what dose the 'cube' mesh look like?

my guess that the model has some self intersecting geometry + ngons that unity isnt able to process so its just discarding it

[astral raven]

its the actual door without the handle

it also gave me similar warnings with the house but I discarded them before cuz I thought they werent a problem

[wanton trellis]

means you got non manifold geometry

[astral raven]

what does that mean

[wanton trellis]

"Non-manifold geometry refers to 3D mesh structures that cannot exist in the real world because they do not form a closed, consistent volume"

Sometimes it can be tolerated, but intersecting geometry is a big no no

[astral raven]

ohh makes sense

so its something I shouldnt really worry about since unity took care of it right?

[wanton trellis]

no you should worry about it

read what the error is telling you

you cant control how unity cleans the mesh up

its good practice that your mesh is functional before you export it from whatever 3d software you used

[astral raven]

well I looked around and I saw no issues so

[wanton trellis]

use blenders select by trait feature

[astral raven]

What does it do

[wanton trellis]

Lets you select any non manifold geometry

[astral raven]

Oh alr thanks

[agile solstice]

Because not all non-manifold geometry is self-intersecting, and not all manifold geometry is guaranteed to not become self intersecting upon exporting, this isn't a surefire way to look for issues
The issue most commonly occurs when a mesh with a weird shaped n-gon is exported, which Unity cannot interpet as triangles correctly
N-gon of such shape could be L-shaped, or otherwise convex in its edges
A quad could also be self-intersecting if any of its edges are crossing through each other, but that usually looks screwed up in blender already
I think the most effective way to work around the issue is to see which polygons were removed and go back to cut them into quads or triangles
Or to triangulate the whole mesh before exporting, which reveals the problematic polygons, or avoids the problem as blender has a variety of smarter triangulation operations than fbx exporter or importer do @astral raven

[astral raven]

Oh alright thanks

[heavy badger]

yo, anyone know how to make an animation non-descript in unity? Like just a generic transform animation thatll work on both game objects A1 and A2?

[agile solstice]

Animation clips store component property overrides by gameobject name and hierarchy path
So as long as the names, paths and components expected by the clip match, they can be used on gameobjects that are different in other ways
Such as having components or child gameobjects in addition to the ones the clip is concerned with
The root gameobject name doesn't matter, also

[wind silo]

can someone help me understand the override transform constraint? what I am doing is first having a transform look at smth via multi-aim. then I want to offset this a little so I use override transform in pivot space. from reading the docs I am guessing what should be happening is it the transform starts at its default pose, gets rotated by multi-aim to face the target and then some more rotation gets added by override. what is actually happening is that override seems to just consistently add more and more rotation to the transform. it basically persists over multiple frames. if I set the weight of override to 0 while in the middle of it breaking it also just stays broken. like shouldnt it instantly reset to default -> multi-aim -> thats it, instead of keeping the override rotation that has 0 weight rn? I am confused.

[heavy badger]

ooh okay thank you

[frozen bison]

Hey all. I have an armature imported with another armature (an animated object) parented to it. For some reason Unity isn't able to find the animation state for the child armature. Any ideas?

The clip for it exists so it should be fine but there's probably something I'm missing

nevermind for some reason upon reimporting it just removed the reference to the animation clip. I guess if anyone has a similar issue that might help. Be sure to check the clips again

[royal olive]

Heya so I'm helping my friend with their project in Unity and he's decided to use animancer but ran into this issue, any ideas?

We think it might be an issue exclusive to animancer, and while we would use the animator in Unity we felt that could come with technical debt due to it duplicating variables, unlike animancer.

[limber dagger]

Just a question, probably to generic (apologies, don't be judgemental), but how much can it potentially cost to animate characters (3D, third person, something like World of Warcraft style) to have smooth movement (run, walk; rotate and strafe; casting, attacking)?

[wanton trellis]

cost as in to pay someone to do it?

youre better of just looking up people offering those exact services online and seeing for yourself

[thin grove]

hello, beginner q: what's the best way for two different animations, which override different properties, to play independently from each other? In my case the properties are color and sprite: the color animation has to play regardless of whether the sprite animation is active. The way I understand it only one animator state can be active at a time so how would it work?

[terse gust]

its probably a simple issue

will need more info

such as how things are setup etc

animancer is just using what the animator uses as well but low level in order to have better control over everything

so this problem would be same on both

[terse gust]

you can use 2 animators XD, or have one animation which has both combined

you can't play multiple clips at the same time on a single animator

you can blend clips etc but not both working at the same time

[agile solstice]

Animation layers in the animator

Animators can be nested, being responsible of separate gameobjects, but not sure if different animators can control the same gameobjects even with separate component properties
Sounds like it'd be prone to conflicts

[royal olive]

Alright sick, I'll ask him

[terse gust]

haha he should ask directly here

He's not in the cord, I'll just chuck him an invite

Man Google is not being helpful anymore. So I'm trying to export a character from Blender to Unity in fbx format. In the past, I have done this by doing one FBX file for the character and all animations. Instead, I would like to export one character file and several animation files. I have seen this done for other assets and I'm betting it will be less taxing for my git repository.

But I am not seeing a batch export process and trying to google it is coming up with nothing but answers to questions I am not even asking. Is there a way to batch export fbx animations into seperate files or is doing them manually, one by one, my only option, because that seems really stupid.

[wanton trellis]

theres no built in way to do this in blender no

you would have to use some kind of custom python script for this

[silver temple]

That's dumb. But thank you for the answer.

[wanton trellis]

or if youre animations are all seperate actions

you can use nla strips

[silver temple]

They are, what do you mean?

[wanton trellis]

look up nla strips

[silver temple]

Just NLA strips? No other context like how to batch export them into separate fbx files?

[wanton trellis]

nla strips will let you export them into 1 fbx, but you can "extract" the individual clips out of them inside of unity

so its as close as you can get with built in tools

[silver temple]

I'm not trying to put all my animations in one FBX file though.

The whole point is I only want to update my animation files if that particualr animation changes, rather than updating the entire fbx

[wanton trellis]

"but you can "extract" the individual clips out of them inside of unity"

at the end of it all in unity you will have your fbx for the model, and several animation clips which are just skinless fbx models

if you need to update a singular animation, just do that and replace it individually

[silver temple]

Is that a different process from duplicating the clips, because I see no option to 'extract' my animations.

[wanton trellis]

you just grab them and copy paste them outside of the fbx

[silver temple]

Ok, so no, its not a seperate file then. Its one file with all the animations that I would still need to update on git and then several copies of the individual animations which I would break references to any time I wanted to update them because they are copies and not references to the original animations and they too would also be pushed to git increasing my repository size which is the exact opposite of what I want.

[wanton trellis]

okay then... use a custom python script if the workaround bothers you so much

[silver temple]

I just don't understand why such a useful feature wouldn't be built in.

Or certainly someone should have made a package by now.

[wanton trellis]

blender is open source

be the change you want to see in the world

Hello team,

An animator will only run, one animation layer at a time?

[silver temple]

How is it after 13 years Unity still doesn't have an option to import animations with constant curves? I just want stop motion animation and people have been asking about it on the forums since 2013. There still doesn't seem to be a good solution for this.

[brave storm]

No it can run multiple at the same time. For example you can have a base layer that affects all bodyparts, and then another layer that only affects the upper body

[agile solstice]

All layers will always be running, whether synced or independent
Layer weight, masking and if it's additive will determine if the motion from it will be applied

[agile solstice]

I believe you can import constant curves, as long as you disable the resampling and or compression, not sure which were required
Potentially useful workarounds are to change the curve to constant only after importing together with exporting with such a low sample rate that baking and resampling cannot create new kind of motion between keyframes
What we really are missing is a good way to snap the whole animator time
Even with correctly constant curve clips, any blending will ruin the snapped effect

[silver temple]

Apparently that option is not available for humanoid rigs.

What do you guys typically recommend for controlling your animations in game, the default animator, controlling it through code, something like animancer, or another option?

[wanton trellis]

It massively depends on many factors

like the first and most important question is, animation for what?

the player? the enemy?

is it a 3d game? 2d? first person? third person?

theres a lot of factors here

[native pewter]

3D game, platformer, starting out with the main character, third person.

There's going to be a lot of animations

[wanton trellis]

Depends on how much effort you want to put into it

i would say the regular animator works

but a part of me also wants to say that if you can find 50 something animation clips

you might want to do motion matching

[native pewter]

I'm worried about it getting cluttered and difficult to debug when a lot of animations are introduced

[wanton trellis]

thats always going to be an issue

regardless of how you implement it

[native pewter]

I was just doing some light digging and a lot of people recommend Animancer. I am just not sure how good it is, or how much it's worth - the price isn't an issue at all.

[wanton trellis]

its really a choice

i used animancer before

and its honestly whatever, just a custom playables api

[agile solstice]

Making effective and efficient animator state machines is a skill
The more you use animator's features like layers, blend trees, sub-state machines, start/end nodes and animator state behaviours in a strategic way, the more you can cut down clutter and automate the motion
Animator's particular advantage is in blending states, and motion that flows naturally from state to state

[native pewter]

Alright, so as a beginner you would probably recommend me using that

I mostly just see animancer's author recommend animancer so I'm not sure how much better it practically would be

The main pitfall of animator is that playing its states directly, which could be intuitive, doesn't give you any benefit from using it at all and in fact hinders you

In similar vein a common mistake is to make a parameter for every state, and transitions between every state or with Any State, in an attempt to let you call any animation at will
But that effectively leads you to code a parallel finite state machine just to manage which state the animator is meant to be playing

[native pewter]

Wait, can you not just call the animator to play an animation on it?

[agile solstice]

While the actual power of parameters in animator is that setting one parameter can play different animations depending on context, or transition through multiple states to naturally reach the desired state
Both of which would be cumbersome tasks to do manually from code each time

[agile solstice]

You can, and that can be a useful tool, but it's important to note it interrupts the state machine's transition logic to skip to the manually called state
Which is likely to contradict the proper workflow

[native pewter]

I'll have to use it to get a feel for it

I haven't really touched it too much yet

Like if I am running, and get hurt into a knockback animation - I am able to call in code to change my state right? cleanly?

[native pewter]

So what's the workaround here

[agile solstice]

The situation could be more like that you have a running knockback animation and a mid-air knockback animation (and maybe more)
So in that case you need animator parameters for running, knockback and vertical motion, your code naively sets thise parameters based on what's happening, and the animator then chooses the animation to play depending on if it's first playing running state or mid-air state, or if it's on grounded layer or mid-air layer for example
Instead of you having to code every one of these conditions if it's using the animator for nothing but playing the state directly

[native pewter]

Can you not directly call what animation should play, from code based on conditions?

[agile solstice]

Then your character may land during the mid-air knockback animation
Blending to grounded knockback animation from the mid-air knockback animation seamlessly without altering the time of the animation would be trivial with animator, but a bunch of work in code

[native pewter]

Or do you have to set those parameters in the animator and have it transition on its own

oh this would probably be bloated in code

with all these different situations

[agile solstice]

You can, but do you want to
People who dislike the animator tend to be using it like that and getting none of its benefits

That said playing / blending to a state directly is a valid tool
As is using a specific parameter and Any State to jump to a state on command
But trying to work the animator with those alone is a hurdle indeed

Mostly because you do end up having to code systems for transition conditions, which the animator has already

[native pewter]

I feel like I need to use this first, run into pitfalls, and come back here once I am more experienced. I don't fully grasp the pros and cons of the system yet, and I think simply using it would make it easier

I also don't want to fall into mistakes and bad habits though

This guy has a series of tutorials I am going to check out before starting

[agile solstice]

I agree
I recommend reading the documentation carefully, especially about the features it has
Because the efficiency lies in those features, and working around them instead leads to inefficiency

[native pewter]

I've already made a couple of animations in Maya to get started

[native pewter]

What specific documentation?

https://docs.unity3d.com/Manual/class-Animator.html Not this, right?

[agile solstice]

https://docs.unity3d.com/6000.0/Documentation/Manual/AnimationStateMachines.html
Everything here basically
That youtuber has videos covering some of these topics on a basic level, but I'm not sure if he really gets into the efficient animator controller strategy

[native pewter]

Do you have a video or series of videos that covers this?

[agile solstice]

None that I'd have found
I'd make one myself if I wasn't doing something else all the time
It's a bit difficult topic to instruct too because the ideal controller varies a lot on what it needs to do and what'd be practical in the unique situation, kind of like how optimization is different for every game
Fortunately there are no big secrets there either, just first learning what the tools are and then figuring out how to use them in a way that works the best for you

[native pewter]

Im going through the docs right now, a lot of this makes sense to me

If you do it properly, you can make this clean right?

[agile solstice]

I can give feedback and advice once you are building an animator state machine to suit your character's particular needs

[native pewter]

With sub states, blend trees, etc. it seems like you can cut a lot of clutter

And also Any State seems very useful

[agile solstice]

Yes, ideally code is very hands-off, just sending parameters as directives of what the character is doing, with the animator fully automating the actual playing of the animations

[native pewter]

Okay this actually makes sense

No matter what though it feels like I'd have to expose and update a lot of parameters for the animator

[agile solstice]

It can be, but it is very treacherous
Any State transitions interrupt all other transitions and the whole state machine, as kind of an "emergency override"
It feels like it gives you, meaning your code, precise control over the state that plays, but doing that takes the responsibility of managing state transitions away from the animator

Then you end up writing conditions in code to prevent the Any State transitions from taking over

[native pewter]

Ah

If you rely on it too much, it can hijack animation transitions - leading to unexpected results

and it turns into this complex balancing act

It's a crutch basically?

[agile solstice]

Indeed

I'd rather prevent beginners from using it entirely, to not learn bad habits
But it has its uses

[native pewter]

Well let's use the knockback as a hypothetical, let's say I can be knocked back from literally any state: walking, running, jumping, wall climbing, etc.

how would you approach that?

having a transition from every single one of those, to the knockback state, that would be silly right?

[agile solstice]

Any State is okay for transitions to states that are totally one-way, or supposed to interrupt everything, something like a death animations
And instead of calling a state directly, Any State transitions can have more conditions, like different death animations along with other parameters, or on other layers

[native pewter]

Okay noted

As a side question, I have a bunch of different idle animations - i want them to play randomly after X duration, can that primarily be done in the animator?

I dont know if it has a way to pick a random animation

[agile solstice]

Idle, walk and run together often can be a blend tree controlled by just one "horizontal velocity" parameter
Jumping and falling can both be controlled by just one "vertical velocity"
Or there can be separate layers, potentially synced, for grounded, climbing and mid-air states
These kind of strategies already cut down the number of required transitions and parameters down a lot

[agile solstice]

I wish there was a feature for a state containing a selection of animations, but it can be done with a sub-state machine and a random value parameter, which you can re-use for any randomization in the controller
Blend trees can also be used to conveniently contain a selection of animations, if you snap the weight variable to increments, but it's a bit hacky

[native pewter]

Oh wait the blend tree idea is really good

[native pewter]

If that's a lot for you, how are you going to get anything beyond that done?

how do i fix my animations not working

i have my animation set up to entry in the animator tab and nothing happens when i press play

[wanton trellis]

we need some more info

did you verify the animation clip works

how are you playing the animation?

what do your states look like

[vapid scaffold]

i press play with a camera in hiearchy to test

it was working yesterday on a different object

[wanton trellis]

does this object have a proper rig/avatar set up?

does it have an animator?

[vapid scaffold]

ye

im exporting a blender animation to unity

it has a bunch of different animators

so i just do the first one

[wanton trellis]

those are animation clips

not animators

im asking if your game object has the animator component on it

[green spear]

Eventually im gonna hire someone

[vapid scaffold]

yes

[green spear]

Just rn i cant afford it

[wanton trellis]

well youre going to have to do that sooner than later im afraid, also we do not accept collaboration or hiring posts here

[wanton trellis]

does any other clip play?

[vapid scaffold]

no

[green spear]

I understand now hiring posts but why no collaboration

That sucks

[wanton trellis]

same reason

hard to moderate

leads to bot spam

[green spear]

Do I need to delete that message or anything?

[wanton trellis]

You probably should

[green spear]

I still think its stupid

Time to try to find somewhere else

[wanton trellis]

theres always #1161868835423526933 if you want to complain

[wanton trellis]

but let me be blunt here

chances are nobody, and i mean nobody will do this for you, not for free

[green spear]

Id rather not because it makes sense why that rule is there

[wanton trellis]

youre better off spending your time learning to do it on your own,

than asking random people in public discord servers to do it for you

[vapid scaffold]

yo question @wanton trellis

i have 5 coasters

i got the anims working for 1

how do i do the other 4

[agile badge]

I am having a huge problem with the IK of the arms in my game. I have an item that is animated to be held by the player, and I want the arm to move with it, so I made a TwoBoneIKConstraint and made a RightHandTarget transform that gets moved to the item everyUpdate(). But this causes the IK to be delayed, and it's very visible on lower fps.

Here is a clip showing the problem, the selected Transform is the RightHandTarget. I believe it's behind by 1 frame, which makes me think that the transform gets before the animation is updated.

[terse gust]

try lateupdate

[agile badge]

I already tried this, doesn't seem to make a difference

[terse gust]

basically

its an ordering issue

you need the item to move before you set the position and you need to set the position before the animation rigging thing is updated

[agile badge]

Yeah, my guess is that I have to update between the animator updating and the animation rigging update.

I just don't really know how to do that

[terse gust]

you can take full control of the entire thing using playables or maybe manually update the animators(tho idk whats the best way to do that)

[agile badge]

I tried making a custom constraint for the animation rigging, but that requires me to Rebuild the rig every time I equip an item

[terse gust]

why would it require that

why do you need to rebuild the rig?

[agile badge]

Since I am changing the target and hint

[terse gust]

does this issue go away using the custom constraint btw?

as you can make it right before the ik constraint ?

[agile badge]

I believe it did, but it was a bit problematic to work with

[terse gust]

ik but for this i think it's not that bad

about rebuilding the rig

[agile badge]

the character seems to flicker for other players when I rebuild the rig

[terse gust]

you can make a parent object which isn't supposed to be re set

yes don't rebuild the rig

avoid that

[agile badge]

if I understand you correctly, this is already what I am doing, I have a RightHandTarget and a RightHandHint that's always set on the IK, and then I have two other transforms in my item that they get moved to every Update

[terse gust]

so why do you need to rebuild if you aren't changing the constraint setting?

[agile badge]

well, I am changing the constraint setting because I need to tell the constraint which transforms to follow

But I removed my custom constraint, because it was basically the same as setting the target and hint on the IK directly

[terse gust]

so you change the target transform?, you have a RightHandTarget and a hint, you are setting those to different transforms at runtime

thats why i am saying instead of modifying the target transform on the constraint, set the parent of the already set target (transforms) to your target you want and reset there local position

[agile badge]

Yes, in my character I have RightHandTarget and hint (which are applied on the IK), then in my Items I also have RightHandTarget and hint, which the ones in the character follow, so I don't have to rebuild the rig

[agile badge]

I tried, but this doesn't seem to work

[terse gust]

like what didn't work

did your transforms not react\

[agile badge]

The hands don't follow

[terse gust]

to the parent or smt

[terse gust]

ah

[agile badge]

Maybe I did something wrong, because I did it at runtime using the hierarchy, but still should work

[terse gust]

then parenting won't work, you need to manually do everything lol, i remember how horrible it was, so i just used unity's humanoid mecanim

[agile badge]

What is that?

Does my character have to be a humanoid

[terse gust]

if you want to use mecanims built in ik then yes

[agile badge]

I couldn't get my character's animations to work with humanoid, so I used generic instead

[terse gust]

there are ways to manually update rig builder also, so like you set the positions of the 2 transforms you want to match and then update the rig builder which ensures

[agile badge]

seems like a performance pitfall, but I could try

[terse gust]

don't update animator manually only the rig builder

[agile badge]

do you know the method of the top of your head? I used some SyncLayers() or something in the past

[terse gust]

wait a bit , i have to check my code lol

ok so, my animator is fully custom using playables, however it should work with animator also, basically have a ref to the rig builder, call Build() on it, set it's graph to manual time update mode, all in start, then in late update call sync layers on rig builder and maybe evaluate on the graph

this may not work tho, hopefully will also https://discussions.unity.com/t/rigbuilder-manual-update/827763/2

check this btw

it seems like it should work

@agile badge the discussion

i gtg now

[agile badge]

alright, thanks for the help! I appreciate it

This seems to have fixed it. Although, my character's arms are in T-pose, but the rest of the body is animated

[terse gust]

not sure what that means character arms in tpose? i mean that is anyways controlled by the IK,

[agile badge]

well the weight on the IK is 0, so it shouldn't care about the arms

when I disable the manual evaluation, it works normally

[terse gust]

so it works when IK is 1

[agile badge]

yes, the IK itself works perfectly now, but the arms are in T-pose

[terse gust]

thats really odd XD

try setting overall rig weight to 0

[agile badge]

I'm so close to buying FinalIK, I've been having problems with my IK for months now

[terse gust]

haha lol

[agile badge]

I already tried this :/

[terse gust]

does your animation even have hands animated?

[agile badge]

Yes, but I also have a Locomotion layer in my mecanim animation controller

so it should default to the idle animation or whatever

[terse gust]

so you have 2 layers orsmt

maybe try not calling build on the rig builder tho that shouldn't make difference

[agile badge]

This is my script, when I disable it in the hierarchy (at runtime), the t-posing stops

using UnityEngine;
using UnityEngine.Animations.Rigging;
using UnityEngine.Playables;

[RequireComponent(typeof(Animator))]
[RequireComponent(typeof(RigBuilder))]
public class ManualRigTick : MonoBehaviour {
    private RigBuilder rigBuilder;

    void OnEnable() {
        rigBuilder = GetComponent<RigBuilder>();
        rigBuilder.enabled = false;
        if (rigBuilder.Build()) {
            rigBuilder.graph.SetTimeUpdateMode(DirectorUpdateMode.Manual);
        }
    }

    void LateUpdate() {
        rigBuilder.Evaluate(Time.deltaTime);
    }
}

[terse gust]

ehm

why do you disable the rig builder

on enable

[agile badge]

It says to do that in Unity's documentation 🤷‍♂️

it's to disable the automatic SyncLayers() updating

happens in rigBuilder.Evaluate already

[terse gust]

hm, comment that out and see

also try it without calling build at all

just setting the update mode

[agile badge]

commenting out enabled = false didn't change anything

trying not to build

still doesn't work

[terse gust]

hm lol it usually doesn't do this weird things, try rigBuilder.graph.Evaluate( instead of the direct evaluate

like in the discussion i linked earlier

[agile badge]

I used that earlier with the same problem, all Evalute does is;

SyncLayers has to be called before Evaluate

[terse gust]

welp im out of ideas lol

[agile badge]

yeah it's weird

I'm just 100€ away from a working solution 😭

[terse gust]

so it's ok without manual updating

but not ok when we take control

[agile badge]

yes

[terse gust]

ok one last try, do graph evaluate then call sync layers

[agile badge]

what If I sync again after evaluate

so two times

I saw someone doing that on unity forums

nope, that didn't work

[terse gust]

someone else had the same issue on the discussion i linked

[agile badge]

yeah, I realized after I implemented it

Honestly, I'm just gonna buy FinalIK, it will save me some headaches

[terse gust]

mhmhmh, tho i won't lol

[modest magnet]

i have imported an alembic animation to unity and its not playing. it has an alembic stream player script attached to it which scrubs through animation when i change a variable called time in it. but i cant find a way to change it in the script, i cant find that variable in script at all. how do i play the alembic animation?

[ripe shadow]

Hello, im having a huge problem with inverse kinematics in my project, no matter what i do, it seems the hands of my charecter always lag behind the gun. i was considering the purchase of FINAL IK as a solution but i dont actually know if it would fix this issue and because of the price of the addon, i dont want to risk it. Any ideas?

[agile badge]

If you scroll up a tiny bit, you will se that I had the exact same problem. There is also a solution that kind of works. I ended up buying Final IK and it works very good, but right now, I am struggling to get good results with Final IK since their Arm IK is has limited configuration.

The solution to your problem may be the same as mine, but it depends on your implementation. But I fixed it by updating the RigBuilder manually. Though it left me with another problem which is that layers in the animator don't seem to work correctly.

[ripe shadow]

idk what layers are, so i probably dont use them, but i think at some point i tried manually updating rigBuilder manually and it broke the entire charecter, maybe i did it wrong but ill try again for sure.
Also wdym by limited config for final IK?

did final IK actually fix the issue of lagging behind?

[agile badge]

Yes Final IK fixed the problem for me, but to me, it feels like the Animation Rigging package works better when only rigging arms, but I may have set it up incorrectly. I haven't used Final IK enough to get comfortable with it, so I can probably make my IK better. Some positive things about Final IK is that you can change the target and hint at runtime without having to rebuild the rig (like in Animation Rigging package), you can also make custom IK constraints since you have all the code for their constraints, so it's a lot more customizable.

[ripe shadow]

Oh damn!
So you can have IK targets directly on the gun and you can switch the IK targets to those, without having to manually update them?

[agile badge]

Yes! This was one of my pain points eith the built in IKs

[ripe shadow]

Im doing a full body animation with tilting the body towards where its going and peeking and stuff like that, mostly using IKs but with some underlying animations too. i feel like from what you describe this would be a good purchase, even if i dont know how to set it up properly yet

[agile badge]

Have a look at their documentation and make the call yourself, it seems to shine at full body iks but my game doesn’t use those so I cant give my opinion on them

[ripe shadow]

Okay thank you! i will look into this, im very happy that there is a solution at all :)

[oblique shell]

can anyone help me? Im very new to animation and I want to export the model with its idle animation to unity but I have 3 seperate animations because there are 3 different objects. how do I safe it as one animation? Is that even the right approach what Im doing?

what is the best way to make an animation like that without having the trouble of splitting it into 3 pieces. I now have 3 different objects in unity as well

[ripe shadow]

Its fine to have multiple objects, if you exported as fbx putting an animation on top of the parent object (the one that has all the 3 objects under it) you should be seeing this animation in the editor

[oblique shell]

Im super confused right now. Do I have to give BeeBody, BeeWingL and BeeWingR a player tag, rigidbody, mesh collider? how do I animate that correctly?

Dont mind the second bee that is the not animated one

[ripe shadow]

Wait nvm, i think itd just be easier if you set up a simple rig, or for an animation that simple you could write a simple script to rotate the wings up and down.
I lied initially because i forgot you could do animations without rigs (sorry) 🥲

[oblique shell]

I dont know how to set up a rig for that 😅 never done it before

[ripe shadow]

Or if you dont really ever want to change the animations and its something that will always play, you can add the animations seperately to each part, it doesnt matter much

[oblique shell]

This project is for learning only and I do want to have multiple animations later even tho a bee cant do much :D. Got any good youtube tutorials explaing it? I cant find a suiting video

and why do I got 9 animations?!

[ripe shadow]

https://youtu.be/DDeB4tDVCGY?si=Hzd-xOg4cjsHh5EG
This tutorial is good, especially since you dont have a humanoid.
If the project is for learning, i strongly suggest to get into rigging, it will save you headaches (and give you different ones) later.
This way youll be able to store the animation in a single file

[ripe shadow]

this is just a blender quirk i stg, the charecter FBX file in my game has a duplicate of each animation and i have no idea why, but its not a super big problem

[oblique shell]

so i can just use any of them?

[ripe shadow]

im p sure yes

[marsh quail]

how do you sync the walk/run animation from blender to unity? forward, backwards, etc animations are 2 sec at 30 fps. but i am noticing a lot of sliding

[wanton trellis]

can you clarify what do you mean by sync?

like match the speed?

[marsh quail]

ye

like the character is sliding forward as they are stepping forward

should i be matching the speed in blender before moving to unity or something else

[wanton trellis]

Well yeah you animated around the desired speed approximately

a human moving at 2.5m/s for one moving 4m/s looks widly different in practice

[marsh quail]

in case of the enemy, im using navmesh, any particular way to measure the distance travelled

and is the distance in blender the same as in unity?

like 1m in X axis in blender is 1 in unity X axis?

[wanton trellis]

you decide the speed of the navmesh agent in the inspector

if you set it to move 3.5 then you animate around that assumption

if it changes, you create multiple "gaits"

[marsh quail]

So pick all the enemy stats for movement and decide animation speeds?

[wanton trellis]

decide how fast the enemy moves

animate around that

[marsh quail]

Welp, trial and error, here i come

[marsh quail]

Thank you
