Does anyone know how to apply certain movement to animations ?
Like making the player move during the animation ? - Can that be done with notifies & code ?
Please ping me ! ;_;

jolly osprey Feb 2, 2020, 1:29 AM

#

the "rotate root bone" animation node takes a "mesh to component" rotator in as a parameter - how do I get or calculate that in an anim blueprint?

molten jewel Feb 2, 2020, 2:13 AM

#

do you need to?

jolly osprey Feb 2, 2020, 2:14 AM

#

yes

#

I'm making some progress figuring out why ue4's importing animations w/ a mismatched rotation

#

it seems to be related to parent groups/objects in maya

#

from being off 90 deg on x it's now off 90 deg on z - much nicer to look at!

#

:P

molten jewel Feb 2, 2020, 2:21 AM

#

probably would just punch numbers in until yaw works like yaw

#

multiples of 90

jolly osprey Feb 2, 2020, 2:21 AM

#

problem is

#

if I do that in ue4 the anims import fine but the "internal data" seems to remain messed up

#

i.e. when I run my custom aim anim node on it, it's off by 90 deg on some weird axis

#

that's why I was asking about that mesh to comp thing

#

hey so when you're importing skel meshes, what does your fwd axis end up being? X or Y?

jolly osprey Feb 2, 2020, 2:42 AM

#

ok it's the groups

#

moving the geo & result joints to the top of the hierarchy fixes all my rotation issues

#

specifically the joints

#

well that's a bummer

strange echo Feb 2, 2020, 5:56 AM

#

I've been trying to use UE4 for rendering recently-

mellow mulch Feb 2, 2020, 5:56 AM

#

Cinematics>Add level Sequence

#

then you can add tracks, which are objects or anything in your scene that you want to keyframe

strange echo Feb 2, 2020, 5:58 AM

#

Are you able to render video or images with it?

mellow mulch Feb 2, 2020, 5:58 AM

#

yup

strange echo Feb 2, 2020, 5:58 AM

#

Sorry if the question's a bit basic. I didn't know it could be used for rendering things until I heard about the Mandalorian

mellow mulch Feb 2, 2020, 5:58 AM

#

its very similar to a timeline you find in premier

#

dont worry, im new aswell

#

and i know exactly what your talking about

strange echo Feb 2, 2020, 5:59 AM

#

I was rendering high res images with cinematic cameras before, but wasn't sure if it could do video

#

I was looking for the keyword rendering, maybe cinematic would have been a better choice

amber lance Feb 2, 2020, 7:29 AM

#

hi guys is there a way to make the root bone face the same dir as the mesh? it's always facing 90 degrees to the right

misty dagger Feb 2, 2020, 7:36 AM

#

@amber lance By any chance, can you double check that your 3-D Software doesn't have the same problem? Also is the root bone relative to the mesh, or the mesh follows the root bone and it just happens that is 90° to what you think it's right side

#

Meaning may be your imported mesh and skeleton was imported 90° to the right side

amber lance Feb 2, 2020, 7:37 AM

#

thx for the reply i'm using the default mannequin

#

when the capsule's yaw rotation is 0 the root bone rotation is -90

misty dagger Feb 2, 2020, 7:39 AM

#

I mean, worse comes to worse, you can add local or world rotation on tick to correct your pose

#

it just feels unnatural to do it like this 🙂

#

I never had any problems with the default stuff from epic

amber lance Feb 2, 2020, 7:40 AM

#

i have to use the add bone rotation note to offset the mesh

misty dagger Feb 2, 2020, 7:40 AM

#

But I experienced rotation issues with meshes imported

amber lance Feb 2, 2020, 7:40 AM

#

but the root bone itself already has 90 offset

misty dagger Feb 2, 2020, 7:40 AM

#

It's unexpected to me that the default mannequin gives you problems...

#

I apologize, but I don't think I have an answer ... 😦

looking at the mesh merge code of epic's, it doesn't have any runtime costs once the meshes have been merged, correct?

molten jewel Feb 2, 2020, 8:59 AM

afaik it don't merge meshes but it just runs only one animation blueprint

jolly osprey Feb 2, 2020, 8:59 AM

thats where i was confused

#

jolly osprey Feb 2, 2020, 9:04 AM

#

wrt anim proxies and custom anim nodes

#

do I have to create a custom anim node in order to update the anim graph?

#

I couldn't seem to find a way to do it straight from an anim proxy

#

anim instance proxy

molten jewel Feb 2, 2020, 9:04 AM

#

anim node

#

i mean

#

you technically could skip the graph entirely

#

on the proxy

#

you don't need to make any nodes specific to your proxy/instance type

#

but its largely the point of having a proxy

#

so you can hide your hard coded bone knowledge there

jolly osprey Feb 2, 2020, 9:06 AM

#

hard code bone knowledge...

#

hm

molten jewel Feb 2, 2020, 9:07 AM

#

it its a super big leverage on performance anyway

#

you can put stuff between frames on the proxy

#

pat is a bit tired

jolly osprey Feb 2, 2020, 9:08 AM

#

I've put my code in the virtual bool Evaluate(FPoseContext& Output) function but apparently that knocked all the rest of the anim nodes in the graph out

#

so it was either my anim proxy doing stuff or the rest of the anim graph doing stuff

molten jewel Feb 2, 2020, 9:08 AM

#

would have to look at the code but if you don't call super on one of those it does not run the graph

jolly osprey Feb 2, 2020, 9:09 AM

#

yeah I did, meticulously

#

actually where would an anim proxy's Evaluate() be run? at the start or the end of the anim graph?

molten jewel Feb 2, 2020, 9:10 AM

#

ready for some surprising information?

#

the anim graph runs exactly as its shown in call stack

#

in reverse i mean from the sink out

#

so the answer would be around

#

around

jolly osprey Feb 2, 2020, 9:11 AM

#

huh

molten jewel Feb 2, 2020, 9:11 AM

#

like if you have a blend node

#

that takes pose a and b

#

when that node askes pose a to evaluate

#

it does, its all a call stack

jolly osprey Feb 2, 2020, 9:12 AM

#

sure

#

that I get

#

but where do anim proxies fit in in all of this?

#

they don't have a node per se

#

not unless you make one

#

so proxies w/o nodes is the question I guess

molten jewel Feb 2, 2020, 9:12 AM

#

the proxy holds the entire graph in it

#

animation graph

jolly osprey Feb 2, 2020, 9:13 AM

#

so by around you mean either as the very first node or the very last

#

yiss?

molten jewel Feb 2, 2020, 9:13 AM

#

you know how the graph ends at the sink?

#

the guy running - node

jolly osprey Feb 2, 2020, 9:14 AM

#

yes

molten jewel Feb 2, 2020, 9:14 AM

#

you can think of that node as the proxy

#

the thing connected directly into is the first node to run

#

and it checks things its connected to

#

back

jolly osprey Feb 2, 2020, 9:14 AM

#

got it

molten jewel Feb 2, 2020, 9:14 AM

#

then forward

jolly osprey Feb 2, 2020, 9:15 AM

#

proxy == 0th node

molten jewel Feb 2, 2020, 9:15 AM

#

ye

jolly osprey Feb 2, 2020, 9:15 AM

#

stupendous

#

so what's the use of the Update() function when there's Evaluate()?

molten jewel Feb 2, 2020, 9:16 AM

#

so theres like this triple tier thing

#

update runs while it basically ensure the event graph data (AnimInstance) is not going to be messed with at all.

#

its not the same thing as on the game thread

#

but it ensures that whatever is on the anim instance wont be changed with thread locking

#

i call it triple tier because you end up having multiple copies of data

#

anim instance has copied data, and then each node has copied data

#

but anyways

haughty parrot Feb 2, 2020, 9:18 AM

#

So I made this animation for the mannequin, and the anim plays fine when I edit the anim, but when I use the anim in-game only the hand moves a little.

molten jewel Feb 2, 2020, 9:18 AM

#

update should be quick, after update eval runs in a really unconstrained thread safety timing

#

so your supposed to treat the anim instance as unreachable in eval

jolly osprey Feb 2, 2020, 9:19 AM

#

both are dispatched to multiple threads via task graph, correct?

#

(update and eval)

molten jewel Feb 2, 2020, 9:19 AM

#

1 character 1 thread

#

yeah

#

i dont' know the exact details

jolly osprey Feb 2, 2020, 9:19 AM

#

so order is 1. update 2. eval

molten jewel Feb 2, 2020, 9:20 AM

#

yeah update before eval

#

btw

#

what i just said

#

thats specific to nodes

#

the proxy does run the nodes too, but proxy also runs the pre update bp invoke etc

#

by phoning back to the anim instance

#

so update animation is different in bp land

jolly osprey Feb 2, 2020, 9:21 AM

#

pre-update being run on GT

molten jewel Feb 2, 2020, 9:21 AM

#

yeah event graph is always gt

#

none of the graph runs on gt unless you say it needs to or fail to lightning bolt nodes that take non pose pins

jolly osprey Feb 2, 2020, 9:22 AM

#

right

#

so what do you use update for?

#

that you couldn't do in eval

molten jewel Feb 2, 2020, 9:23 AM

#

Eval technically is always possible to thread

#

Update is where pins are read

#

And stored to memory

#

You get no pose info at this point

#

Then evaluate happens

#

It does a full trip

#

Through the stack for each

jolly osprey Feb 2, 2020, 9:26 AM

#

great!

#

still not getting what the use of update is but this has been helpful :)

molten jewel Feb 2, 2020, 9:26 AM

The one argument is passed all the way back

Is there a "proper" way to export/import skeletal meshes and animations to/from Blender and Unreal? It seems like every time I move between the two, either the scale is messed up, the skeleton, or any other number of things.

Hi all, I'm trying to implement LODs which strip out bones at higher LOD levels. My character is modular (separate meshes for chest, head, legs etc), so I went through every mesh, generated the same number of LODs and removed the same bones from each one. When I view each mesh in the editor, I can only count 14 bones at the highest LOD, but in game when using a.VisualiseLODs 1, it says "RequiredBones" is 23. I have no idea what those extra 9 bones are

#

Is there a way to show in-game the names of the bones? ShowDebug BONES doesn't show any information, show bones doesn't give the names, showflags.bones 1 again just shows the wireframe skeleton but no bone names

#

When I manually count the bone names in the mesh editor, I can only see 14 listed, so I would be really curious to understand why VisualizeLODs says the animation has 23 required bones

#

My setup is that I have 6 skeletal meshes, with the chest mesh being the parent of the rest. Every mesh is set to adopt the same LOD as the parent, so they're not calculated independently

#

and also use the same master pose, so they aren't independently animated either

Anyone in here would know how i can weight an IK in one specific direction? I am using a plugin to do VR IK and it works rather well but I'm running into the issue that the arm of my character tends to want to go inward and I'm trying to pull the elbow outward.

The developer of the plugin recommended using Two Bone IK but I am unsure how to use 2-bone to only weight the position of the middle joint and leave the rest of the system nearly unaffected.

keen solstice Feb 3, 2020, 8:29 PM

Have you tried root motion? Idk if that moves the capsole component though. If it were me, I would tweak the animation in blender to keep the animation in place and use a timeline and code in the movement of the capsole component, but Idk if this is a good way to do it. (i never used root motion so idk of that will work for your situation)

General question for animators here: Supposed you have a spaceship of sorts that has some parts that can transform - hidden thrusters for example, like in this example:
https://youtu.be/rUerackEBs0

Why is stuff like this so rarely seen in games? Is there a technical reason? I can imagine that if you had a skeletal mesh (a robot for example) that had transformable parts, keeping transformations in tact with old animations might be tough to do or something? Although I guess additive animation would do the trick? I'm not an animator so some explanation would be much appreciated.

figured it's doable, but what would the workflow look like?
Just regular skeletal animations and applying an additive animation to keep the thrusters activated while still being able to use regular locomotion animations? Blend shapes are probably not the way to go, as the anim is too complex for blend shapes, is that correct?

heavy needle Feb 3, 2020, 10:15 PM

#

just use the state machine for that.

frigid drum Feb 3, 2020, 10:17 PM

#

if state machines cant cut it, for example because of the many combinations, you can also blend specific bones, also yes, additives are really easy way to make locomotion + other animations together

using the state machine would be counterproductive, as that's would imply doubling all the animations and tweaking them every time you add a transformable part just to keep up with the combinatorial aspect of it..

@frigid drum okay thanks, thanks for confirming. Once I find the time I will experiment with additives, sounds like it's what I'm looking for

keen solstice Feb 3, 2020, 11:14 PM

👀 anyone know the solution to the issue I posted above?

#

the problem with the animation not playing properly when I attack. It seems to be interpolating the animations together and I don't want that

heavy needle Feb 3, 2020, 11:17 PM

#

I think its the blend time of your montage. blend in blend out. they are .25 by default. set it to .1 or .01

keen solstice Feb 3, 2020, 11:17 PM

#

oh I didn't see that option. It's my first time working with anim montages.

#

I'll see if I can find it.

#

also I do want it to blend out of the animation but not in

let me check

in maya can you use blend shapes in animations for unreal?

Don't know how though. Still learning this stuff 😓

consider pausing the montage when you make a hit

like two frames or something

@misty dagger it's a montage animation, which does translation in persona but not move camera in world

misty dagger Feb 5, 2020, 4:34 AM

#

@spring bloom Rotation is just a convention, right? So let's say what you consider facing you is 0. So left is -90 and right is 90. Then at any given time anything between 0 and -90 is being hard clamped at -90. Anything between 0 and 90 is being hard clamped at 90. Which basically makes the character always either face full left, or full right, No more in betweens 🙂 and only when switching from (-90,0) to (0,90) allow that smooth transition animation for rotation, say half a second. Just brainstorming, not necessarily the best approach 🙂

Hey y'all, what's the fanciest way of doing camera shakes / animations? I've been looking at what's currently there but it looks a bit old. The current camera shake blueprint takes some procedural settings + a matinee sequence, but given that Matinee is deprecated I'm starting to think about maybe trying something else

lean tiger Feb 5, 2020, 9:49 AM

Hey all, I'm having an issue with all my characters when using animations from the marketplace. All my characters use the UE4 skeleton so they all share the same animation and all have the same issue. I'm using CC3 to create my characters and for all the animations, when the arm is going to far back the shoulder heavily deforms as seen in the picture. I tried changing the retargeting options of the skeleton but it doesn't really help. Anyone has any idea what causes this ?

You can edit animations by setting additional keyframes.

You can somewhat. It creates an additive layer though. So it can get messy rather quickly.

#

Side note: when you have every possible entity on a blend space filled like that, you are kind of losing out on the better interpolated animations. Won’t fix the problem but try doubling your grid divisions per axis.

#

Otherwise debug the anim blueprint @steel tree, watch the values your pumping to the node

#

Could print them to screen as well. You likely just need to adjust the rotator before delta node but idk

molten jewel Feb 5, 2020, 4:48 PM

#

@steel tree you may want to consider that blend space the more it runs through my mind too. what are those numeric values for the left and right?

#

may want to correlate them to an inverse signed turning radius or something that makes sense. either way, its a pretty horse and good animations. you likely just need to watch the values as i said already

Hi guys, I have a big problem that I tried to solve for a week, but didn't find the solution. So I've made an animation of a drone helice "opening" , the model is using 4 meshes and they are connected to an armature. On blender the animation looks fine, as I want. But in UE4, when I import it, it looks like everything is messed up, here is a gif to show what I mean :

shouldnt be hard but i cant find how to do that

restive yew Feb 5, 2020, 7:13 PM

#

You’re not editing keyframes @lean tiger . The animation is baked when you export them. You’re basically creating a new animation and having it recalculate with the old animation when you’re use Add keyframe feature in unreal.

Q: Montages and looping. Using straight animBP and the state machine I can easily let it blend between states for each attack in a combo. when swapping to a montage as recommnded if I loop combo 1-3 after 3 it loops back to 1 but does not blend. What is the correct way to fix it so it blends correctly? What I have read the animations need to be set up correctly to play back to back as the montage system won't handle the blending.

molten jewel Feb 6, 2020, 12:56 AM

#

Montages are my weakness when it comes to animations.

#

Not sure if you can alternate them and then manually blend them with alphas calculated on the event graph

#

but perhaps that'd work

heavy needle Feb 6, 2020, 2:06 AM

#

you answered the question yourself. its basically one long looping animation which is cut into 3 parts and then put together in the montage, so you can stop them with notify event. frame 1 on animation 1 is identical to the last frame of animation 3.

nimble hatch Feb 6, 2020, 2:41 AM

#

damnit ok that is what I was worried about. The animations are not intended to loop just those 3 (its a 5 part combo) so i can't use montages to loop the first 3 together I would have to use the state machine . booo

molten jewel Feb 6, 2020, 2:44 AM

#

cached pose with state machine is a thing

nimble hatch Feb 6, 2020, 2:44 AM

#

I have it working fine with a pure state machine but wanted to use montages as people seem to recommend them as the right way and it definetely worked well its just got crummy animation now lol

molten jewel Feb 6, 2020, 2:44 AM

#

but gets complicated for sure

nimble hatch Feb 6, 2020, 2:44 AM

#

yeah just dropping the anims into the montage and letting them loop is a problem. I would have to maybe play the montage for the 3 attacks then "pause" and let the anim bp blend it back to the idle or first attack, then play the montage again lol

#

its all just learning right now so learing all the bad stuff / issues with all the systems is still good =)

molten jewel Feb 6, 2020, 2:46 AM

#

yeah, if the transition times are similar and part of the reason for the montage is different weapon types (assumption) you could just assign the animation by pin too in the state machine

#

but yeah I'm not familiar enough with montages to really advise much on them.

nimble hatch Feb 6, 2020, 2:46 AM

#

ok so im farting around with the free 3d character lo poly stuff that was for a month. It has 5 weapon types and each weapon has a 5 comboattack

#

setting it up in anim bp in a state machine was easy enough if attack was held down I just moved from one attack to the other. In the montage i just tell it to play and it stays looping but without a smooth transition from 3 -> 1 it looks crappy lol

#

the anim bp of course blends transitions automatically if you tell it to

misty dagger Feb 6, 2020, 2:48 AM

#

You can have longer or shorter transition times, depending on your need

nimble hatch Feb 6, 2020, 2:48 AM

#

yeah but can you transition in montages is the question/issue

#

pure montage, 3 sections, looping from 3 back to 1

molten jewel Feb 6, 2020, 2:49 AM

#

I just meant, you can checkbox the thing on the right

📎 unknown.png

misty dagger Feb 6, 2020, 2:49 AM

#

worse comes to worse, timers?

molten jewel Feb 6, 2020, 2:49 AM

#

then store your weapon animations to variables on the bp, set by event graph

nimble hatch Feb 6, 2020, 2:49 AM

#

oh yeah the anim bp stuff works great

molten jewel Feb 6, 2020, 2:49 AM

#

wouldn't be able to specialize transition times, but it'd be a generic way to support all the weapons without copy and paste state machines

misty dagger Feb 6, 2020, 2:50 AM

#

Another way I've done it in a dancing project, switch the camera at the moment of transition, None the wiser 😄

nimble hatch Feb 6, 2020, 2:50 AM

#

well the new anim bp stuff can have sub graphs that you can swap out so that actually makes that one easy to do as well =)

#

but yeah for testing I just have 2 anim bp's that are basically duplicates so consolidating it into a swappable system is a goal

#

all my research so far says montages are the correct way to go but that seems to only help if you have proper animations lol

molten jewel Feb 6, 2020, 2:51 AM

#

hahah

#

yeah, i've not tried the sub graphs. but yeah the thing with them needing to be proper and not fudged sounds like a thing.

nimble hatch Feb 6, 2020, 2:52 AM

#

i ran into trying to figure this out when I added in damage to the weapon, which actually works well, and I was noticing using anim BP that my start notify was getting called twice for some reason (start -> end -> start) which uh... shouldnt happen lol

#

so I was like whooo lets learn montages like a proper animator and WHAM wall lol

molten jewel Feb 6, 2020, 2:53 AM

#

yeah I have had that moment of discovering how unstable notifies are too

#

I tend to avoid relying on notification in general from the graph

nimble hatch Feb 6, 2020, 2:54 AM

#

yeah i think it's due to the blending times overlapping , I know i had an issue with a finish not getting called when it was blending to the next too early

#

I kinda just stopped trying to figure it out to learn montages lol

molten jewel Feb 6, 2020, 2:54 AM

#

first thing most notifies do is make sure they should be running lol

#

don't blame you for avoiding them

nimble hatch Feb 6, 2020, 2:54 AM

#

i mean all the "real" stuff epic has released uses montages and notifies so I figured learning it that way was right but right now...

molten jewel Feb 6, 2020, 2:55 AM

#

When your just putting mp content together

#

its a lot harder to use epic's fortnite stuff lol

nimble hatch Feb 6, 2020, 2:56 AM

#

my attack stuff worked nicely tho so I was happy about that. BP actor which held the mesh and collider. Events on the actor using interfaces to interact with the item it overlaps with. Events to turn on and off the collision as needed and to prevent it from being used to damage more than once per animation

#

and it "seemed" right but once I started debugging the notifies and blends it did not return the expected results lol

molten jewel Feb 6, 2020, 2:57 AM

#

yeah, a looping animation can cause it

nimble hatch Feb 6, 2020, 2:57 AM

#

its all good, got a couple more days Im going to just ingest all the animation stuff on the web and see what happens =)

molten jewel Feb 6, 2020, 2:57 AM

#

but really like, its so fragile

#

but yeah you'll get something going i'm sure. probably just expecting to get whaled on by event calls and checking if its time to run them or not will work most of the time

nimble hatch Feb 6, 2020, 2:58 AM

#

yep I thought the looping would do it but even then it should not have. Just playing the 1 attack animation would do start -> end -> start almost like the animation played then when it was done when it was blending back to idle it would trigger the start again (which makes sense but ugh...)

molten jewel Feb 6, 2020, 2:58 AM

#

ye

nimble hatch Feb 6, 2020, 2:58 AM

#

and by should not have I mean damnit its not what I wanted it to do lol

molten jewel Feb 6, 2020, 2:59 AM

#

i know the anim graph code pretty well and the anim nodes have little to no understanding of what the larger picture is

#

yet they are responsible for firing off the events and everything

#

stuff like avoiding refire is something they just don't do

nimble hatch Feb 6, 2020, 3:00 AM

#

yep it all makes sense I just need to figure out a good flow for events and triggering and blah blah making a game is work

#

its all just a fun project to learn some stuff. i spent like a day just trying to decide if i wanted to allow movement when attacking or locking into the animation lol

#

like half the stuff I am doing is game design and that's just not as much fun as figuring out the code

#

but hey it's all good info to know for passing on to others in the end =)

molten jewel Feb 6, 2020, 3:03 AM

#

Definitely is good info to pass on. Design is tough too yeah

nimble hatch Feb 6, 2020, 3:04 AM

#

Epic needs more animation courses that are updated and past the basic one (which in theory is coming) so trying to come up with the "right" way to do stuff while epic themselves does it in special ways is annoying

molten jewel Feb 6, 2020, 3:06 AM

#

YEah, they just throw tallent at everything 😂

#

Control rig is pretty cool but even that solution is pretty involved for bringing 3 separate sets of animations still

nimble hatch Feb 6, 2020, 3:06 AM

#

in th end it all comes down to everyone does things different even if they are supposed to do it the same...

molten jewel Feb 6, 2020, 3:07 AM

#

Yeah for sure, well its a freedom really. But yeah seeing animation glitches in games is a peeve

#

the way the graph is concealed so hard makes people relying on frame old data way too common

I imported an FBX file
the skeleton body is rotated incorrectly
the animations play correctly

raw relic Feb 6, 2020, 10:49 AM

#

How do i attach and detach a body part of a skeletal mesh? For example i want to take off the arm and leave it in that location and than pick it back up

molten jewel Feb 6, 2020, 3:16 PM

#

You would need to reposition it manually using modify bone

nimble hatch Feb 6, 2020, 5:48 PM

#

so on a silliness scale how far off is this from doing it right? https://imgur.com/a/w5kR68j Basically a walk state machine that handles idle/walk and jumping. an attack state machine that handles the attack como animations. Caching the walk state machine then using it with a layered blend node at the spine to allow movement and attack toblend at the waist. the attack state machine using the cached walk animation as the first node to make sure it blends properly.

#

I had the layered blend inside each state of each attack inside a single state machine but that would just reset the animation for the idle/walk BS every time an attack started lol. this way above "seems" good?

#

Fucntionally and visually it seems to work https://i.gyazo.com/ab4cae2f76eb71532f776e1c28e32b3e.gif as I can cancel any animation and blend properly and the feet seem to maintain the correct walk cycle when attacking

nimble hatch Feb 6, 2020, 7:45 PM

#

holy hell I cannot get my head around the "proper" way to do animation with the systems in UE4 lol. Lets say you have 3 weapons with unique animations (all animations unique from idle to attacks). You want the player to be able to swap weapons so of course the animations need to be able to swap as needed. the animations are not synced properly for atack1 -> attack 2 -> attack 3 -> attack1 -> etc. so using a pure montage for looping makes it look funky lol

#

I was trying to use the new sub graphs but you cant seem to get data into them easily to re use. they swap out easily enough but it's like basically you have a main graph with sub graphs but the sub graphs do all the work of a main graph so why not just swap main graphs lol

molten jewel Feb 6, 2020, 7:46 PM

#

damn

#

maybe @restive yew could help. I don't know as much with montages

restive yew Feb 6, 2020, 7:47 PM

#

Wat

nimble hatch Feb 6, 2020, 7:47 PM

#

I think you are supposed to treat the sub graphs as full on graphs using the event and anim graphs in them to calculate the output but.... I guess maybe a sub graph is overkill for just a simple animation swap system

restive yew Feb 6, 2020, 7:47 PM

#

No one knows the proper way

nimble hatch Feb 6, 2020, 7:47 PM

#

so should I have like 1 main character graph with 5 state machines that I just blend by into to choose which one I want to use based on passed in weapon # lol?

restive yew Feb 6, 2020, 7:48 PM

#

Each weapon has unique animations yes?

nimble hatch Feb 6, 2020, 7:49 PM

#

yep each one has 100% unique animations

restive yew Feb 6, 2020, 7:49 PM

#

gg

molten jewel Feb 6, 2020, 7:49 PM

#

Did you consider what i was saying with the animation assets being swappable? you could use one state machine for all of them if you have a variable for each 5 attacks that you set with the current weapon

nimble hatch Feb 6, 2020, 7:49 PM

#

I know this is an extreme example but I am literaly using the free assets from epic so it's a realistic one lol

molten jewel Feb 6, 2020, 7:49 PM

#

lol

nimble hatch Feb 6, 2020, 7:49 PM

#

swap which assets?

molten jewel Feb 6, 2020, 7:50 PM

#

so if you go to a play animation node matheww you can show the animation by pin

#

and then assign a variable animation reference to it

nimble hatch Feb 6, 2020, 7:50 PM

#

well its more than just the attacks in the issue since the idle is different, run is different, jump is diff, etc.

restive yew Feb 6, 2020, 7:50 PM

#

Sockets. You prevent animations from running if x weapon isn’t active

molten jewel Feb 6, 2020, 7:50 PM

#

yep you could specialize each of these per weapon

nimble hatch Feb 6, 2020, 7:50 PM

#

plus blending % might be different between each weapon so I cant use one state machine with 5 generic spots for attacks

restive yew Feb 6, 2020, 7:50 PM

#

Gets messy

molten jewel Feb 6, 2020, 7:51 PM

#

blending % would be not likely able to change correct.

#

with messy assets though might be an okay solution

#

Montages <- pat does not know

restive yew Feb 6, 2020, 7:51 PM

#

Nah I’m with Mathew, make subgraph

nimble hatch Feb 6, 2020, 7:51 PM

#

before I deleted it all and tried the sub graphs I had basically 2 blend by int nodes with 5 inputs into each based on weapon then the 2 nodes would blend by layer for the spine into eachother so I cold blend the walk/run animation with the weapon animations lol

molten jewel Feb 6, 2020, 7:51 PM

#

I have no idea what subgraph does tbh, another thing i've not used.

nimble hatch Feb 6, 2020, 7:52 PM

#

but the sub graph system doesnt like getting data into it, you can swap them out which is nice but then you just basically do the entire fricking graph again in another graph which seems weird

#

by sub graph I mean linked layers

molten jewel Feb 6, 2020, 7:53 PM

#

hm yeah

nimble hatch Feb 6, 2020, 7:53 PM

#

because even epic doesnt know what to call this shit

#

its under animation layers but layers are completely different in the docs

#

took me a while to find it under sub graph instances lol

molten jewel Feb 6, 2020, 7:54 PM

#

i made wrong assumptions about what the sub graph does tbh, i don't know haha

nimble hatch Feb 6, 2020, 7:54 PM

#

I mean the docs are great https://docs.unrealengine.com/en-US/Engine/Animation/AnimHowTo/LinkedAnimBP/index.html

#

but to get calculated data from a sub graph you need to get that data inside of it, so talking to the character for example, which should be the job on the main graph

#

oh wait now I remember why I didnt like it as well, notifies are not called in the parent graph but this sub graph

restive yew Feb 6, 2020, 7:56 PM

#

This shit is why I stopped animation programming

nimble hatch Feb 6, 2020, 7:56 PM

#

ok so I am not crazy it's really just throw shit and see what works. Hope you have no issues with perf and if you do try and debug it or hope an expert can help lol

#

but I am glad to know that just like every other part of the engine there is multiple ways to do it wrong 😉

#

I don't want to show people the wrong way but... uh.... I can't seem to find competent docs on the "right" way heh

#

all the docs and videos and training are snippets, yay we can play a montage or we can make a state machine for running but not an actual lets do something real lol

restive yew Feb 6, 2020, 8:00 PM

#

Beyond the basic idle-walk-run blend and jumping, you’re in barf to a wall and hope it works territory

nimble hatch Feb 6, 2020, 8:00 PM

#

the action RPG uses montages but they are part of the gameplay abilities system and even then not a very robust system in terms of making stuff animate

#

meh I think I will redo all the work I deleted earlier and see how that goes lol 🙂

#

blah even then thats stupid

restive yew Feb 6, 2020, 8:02 PM

#

Did you look at paragon?

molten jewel Feb 6, 2020, 8:02 PM

#

keep those lightning bolts lit, it'll be fine 😄

nimble hatch Feb 6, 2020, 8:02 PM

#

I didnt look at paragon yet but even then it's not like the weapons swap on the characters? I think only 1 actual anim bp was released for Paragon assets

molten jewel Feb 6, 2020, 8:03 PM

#

I think people that do these animation state machines all the time just throw state code around like popcorn

#

but yeah i don't like the extra maintenance either lol

nimble hatch Feb 6, 2020, 8:03 PM

#

my logical thinking is keep as little loaded as possible. So if you have 5 unique weapon sets of animation only keep 1 loaded at a time

restive yew Feb 6, 2020, 8:04 PM

#

https://tenor.com/bbJfI.gif

Tenor

nimble hatch Feb 6, 2020, 8:04 PM

#

so using the linked layers, to swap the weapon type being used seems smart, but you can't pass in data from the main graph (like speed/is attack) and have it re used in the linked graph. At that point you have to calculate that info the same way as the parent graph so whats the point of the parent if you can just swap full unique graphs lol

#

besides it being an unusable messy non efficient duplicated nightmare

molten jewel Feb 6, 2020, 8:04 PM

#

my head just exploded when you said that

#

so i'm familiar with the subgraph node for post process bp

nimble hatch Feb 6, 2020, 8:05 PM

#

I have more than once just sat here with my head in my hand today

molten jewel Feb 6, 2020, 8:05 PM

#

you can have pin-ins from the calling graph by name

#

does that apply here too?

nimble hatch Feb 6, 2020, 8:05 PM

#

you can and I tried that but passing in the data means it has to be used in the main anim graph

#

which means state machines in the anim graph cant use them since you cant pass in data to the state machines

#

the state machines get the data from the actual event graph which you cant pass data into you have to get it from something like the character which then defeats the purpose and your duplicating shit again

#

which I think... is the right way to do it

#

I just dont like it lol

molten jewel Feb 6, 2020, 8:07 PM

#

ouch that really seems

#

involved

nimble hatch Feb 6, 2020, 8:07 PM

#

the issue is you cant run any execute wires in an actual anim graph so no setting variables

#

the programmer in me just wants to have a ton of re usable parts i can swap in and out heh

molten jewel Feb 6, 2020, 8:08 PM

#

animation blueprints in general with their binding to a skeleton is a thing that makes my inner programmer sad

restive yew Feb 6, 2020, 8:09 PM

#

tracking down one of epic’s animation programmer is going to be your best bet at this point. Especially in your case.

nimble hatch Feb 6, 2020, 8:09 PM

#

I hope I am just missing something. It seems logical to be able to do this but I just havent gotten it to click yet

restive yew Feb 6, 2020, 8:09 PM

#

You are too dangerous 😛

nimble hatch Feb 6, 2020, 8:10 PM

#

I am looking at the shinbi paragon character again btw but even then it's what 2 years old and not using new tech so who knows

#

action rpg is a good example but it's really really really basic in the end

#

no cancelling, using a montage that is called from a GA on the weapon

#

and all the animations are perfectly set up to sync in a chain

molten jewel Feb 6, 2020, 8:12 PM

#

heres some of the things i mentioned

📎 2020-02-06_14-10-36.mp4

nimble hatch Feb 6, 2020, 8:12 PM

#

yep now

#

get that input variable into a state machine that you are using to determine idle/jump/run

molten jewel Feb 6, 2020, 8:13 PM

#

Yeah

#

that input node ..

#

just realized how messed up that is that theres a node on the animgraph coming OUT of variables

nimble hatch Feb 6, 2020, 8:14 PM

#

its great for your example, but once you want to do something outside of the graph itself it's stuck

molten jewel Feb 6, 2020, 8:14 PM

#

yeah

brazen canopy Feb 6, 2020, 8:14 PM

#

Hey all. Is there any tutorials or sample projects on using animation sharing? Couldn't find any of those on the internet((

molten jewel Feb 6, 2020, 8:14 PM

#

i understand the problem now

#

however mathew

#

you can use cached pose

#

make cached pose on anim graph and hook them into states

nimble hatch Feb 6, 2020, 8:14 PM

#

yep but again how do I get that variable, to say drive a 2d blend space, inside the state machine

molten jewel Feb 6, 2020, 8:15 PM

#

lemme see

nimble hatch Feb 6, 2020, 8:15 PM

#

lets say I have a normal use for a state machine (Idle/run blendpace with transitions to a jumping set of animations) just like say the TPP

#

getting the data into that state machine to drive the blend space is the issue. I mean yes I could drive the blendspace outside the state machine, cache it, then put that cache into the state machine

#

which I did do and it works lol

#

but then the next problem I ran into is I am doing a simple transition check using a boolean inside the attack state machine and I can't just pass that into there heh

molten jewel Feb 6, 2020, 8:19 PM

#

yeah i think this would work

#

📎 2020-02-06_14-18-09.mp4

#

but

#

I don't know what can be modified in the event graph in terms of transition speeds alone

#

when it comes to layers, i have even less of an idea

nimble hatch Feb 6, 2020, 8:21 PM

#

well uh

molten jewel Feb 6, 2020, 8:21 PM

#

so even if that cached works (which i'm not positive it does)

nimble hatch Feb 6, 2020, 8:21 PM

#

how do I tell it to actually play the attack pose

molten jewel Feb 6, 2020, 8:22 PM

#

would have to take in all the inputs your current state machine uses

#

er previous rather, the one using a state machine

nimble hatch Feb 6, 2020, 8:23 PM

#

📎 unknown.png

#

idle is an idle BS that needs a speed to determine how fast to play it

#

Attack 1 is transitioned to when the is attack bool is true

#

attack 2 is transitioned when attack1 is done and attack2 will transition back to 1 when it's done

#

attack1 and attack2 both can transition back to idle when attack is false

molten jewel Feb 6, 2020, 8:24 PM

#

yeah i'm understanding more

nimble hatch Feb 6, 2020, 8:24 PM

#

sooo... normally those variables are available since the main event graph gets them

molten jewel Feb 6, 2020, 8:24 PM

#

my solution does not handle transition booleans

#

yeah

#

hm, this seems rather half baked, that input node

nimble hatch Feb 6, 2020, 8:25 PM

#

well I could see it being useful if you only have the event graph grab the data needed for that particular thing

#

like a weapon sub graph using it's event graph to get weapon related data

molten jewel Feb 6, 2020, 8:25 PM

#

as someone that avoids state machine, it works

nimble hatch Feb 6, 2020, 8:25 PM

#

upper body doing the same ,etc.

molten jewel Feb 6, 2020, 8:26 PM

#

but yeah transition pins, these aren't fillable

nimble hatch Feb 6, 2020, 8:26 PM

#

can you toss out an example of that

molten jewel Feb 6, 2020, 8:26 PM

#

an example of upper body only?

nimble hatch Feb 6, 2020, 8:27 PM

#

of the transition pins

molten jewel Feb 6, 2020, 8:30 PM

#

ahh

#

📎 unknown.png

nimble hatch Feb 6, 2020, 8:31 PM

#

ok so silly question but... lets say I had 5 weapon types. I make 5 anim blueprints that deal with just movement (idle/jump/etc) and then 5 more which deal with the attacks. I use the layer stuff to blend them together and swap out what is used based on equipped weapon. Each anim bp (layer) controls it's own variables. The only advantage I can see of this over the others is uh... I have things compartmetalized even more than just 5 that handle movemnt and weapon together

molten jewel Feb 6, 2020, 8:31 PM

#

it looks like in the event graph you can get layers

#

The way i read this right now is, this category looks revealing

📎 unknown.png

#

Question is

#

imagine that there is a master graph

nimble hatch Feb 6, 2020, 8:32 PM

#

yep the linking and unlinking is how you swap them

molten jewel Feb 6, 2020, 8:33 PM

#

yeah, so you can potentially get the master graph in a linked one

#

in its event graph i mean, copy off the variables you need

nimble hatch Feb 6, 2020, 8:33 PM

#

ah gotcha uh I dont know if I can especially since you would have to cast

molten jewel Feb 6, 2020, 8:34 PM

#

You'd use the type of your master animation blueprint with the layers/ the one setting the layers anyways

#

(i think)

nimble hatch Feb 6, 2020, 8:34 PM

#

yeah I dont think it knows the concept of parent. I could get char -> get anim instance -> cast -> get but thats silly

molten jewel Feb 6, 2020, 8:34 PM

#

Yeah it wouldn't be a parent

#

These animation blueprints are classes

#

so you should be able to just use the one master class

nimble hatch Feb 6, 2020, 8:35 PM

#

yep but the ones you link dont know they are even linked

molten jewel Feb 6, 2020, 8:35 PM

#

your sure?

nimble hatch Feb 6, 2020, 8:35 PM

#

yeah the master one would be the anim instance running on the character

#

well I know the master one does know which ones are linked

molten jewel Feb 6, 2020, 8:36 PM

#

📎 unknown.png

nimble hatch Feb 6, 2020, 8:36 PM

#

📎 unknown.png

#

its ugly but for example this is what I use to swap the linked layers when I "swap weapons" in the character right now

#

grabs the current linked one based on the Weapon group and unlinks it so I can link the new one

molten jewel Feb 6, 2020, 8:37 PM

#

hm interesting

nimble hatch Feb 6, 2020, 8:37 PM

#

yep your code would be fine but again at that point I am getting the info from somewhere else (the parent in this case) why not just get it from the actual character who has it lol

molten jewel Feb 6, 2020, 8:37 PM

#

that is what mine is doing

nimble hatch Feb 6, 2020, 8:37 PM

#

efficiency wise yours is probably cheaper

molten jewel Feb 6, 2020, 8:38 PM

#

Get Owning Component is the skeletal mesh component anyways

#

I'm not seeing anything about linked parent though yeah

#

I wanted to assume everything linked was considered linked to eachother but idk

nimble hatch Feb 6, 2020, 8:39 PM

#

I think the benefit of this is just to allow you to compartmentalize but not really make it more efficient or re usable. You still have to create each unique anim bp to use as a layer and they all have to be self contained if you want to use state machines

#

it makes sense but durnit

#

I think I will try the 11 blueprint way and see how that goes heh

heavy needle Feb 6, 2020, 8:40 PM

#

if you just want to swap weapons, you can use a switch on int/enum etc.

nimble hatch Feb 6, 2020, 8:41 PM

#

basically turn the main character anim BP into a shell that holds layers that drive the locomotion and the weapon anims

#

and let each layer handle itself completely

#

... crap that still runs into the issue where the main anim bp doesnt get notifies from the linked layers

#

I guess if I just assume the weapon will handle the notify then problem solved. whoo obfuscation thru 10 layers of code

molten jewel Feb 6, 2020, 8:43 PM

#

the problem mentatz is state machine

#

and transition settings wnating to be different

nimble hatch Feb 6, 2020, 8:43 PM

#

It's a very specific problem due to using very specific assets in the wrong way

molten jewel Feb 6, 2020, 8:43 PM

#

and i agree with you mathew. reusability goes out the window with animation blueprints really.

#

reusability with animation blueprints on the event graph at least is just blueprint macro library everything

nimble hatch Feb 6, 2020, 8:44 PM

#

I think this will work in the end, 11 blueprints but the ability to have each one be tweaked correctly and only have 1 set of animations loaded seems optimal

molten jewel Feb 6, 2020, 8:45 PM

#

its likely not as optimal as one huge graph

heavy needle Feb 6, 2020, 8:45 PM

#

you dont need the state machine for that. if your weapons are just the upperbody for example. all the statemachine has is idle/run BS and jump.

molten jewel Feb 6, 2020, 8:45 PM

#

but it works

nimble hatch Feb 6, 2020, 8:46 PM

#

I really don;t know. I have to duplicate getting stuff from the character but I would assume if I had 1 graph with 10 sets of animations it would use more than just 2 sets

heavy needle Feb 6, 2020, 8:46 PM

#

the paragoncharacters all use lower body/upper body set up.

nimble hatch Feb 6, 2020, 8:46 PM

#

what would you use for weapon combo animations?

#

assuming you cant use montages because you have un optimized animations

heavy needle Feb 6, 2020, 8:47 PM

#

that combo stuff makes really complicated.

nimble hatch Feb 6, 2020, 8:47 PM

#

yep we can do easy, its the complicated that is causing this conversation 🙂

molten jewel Feb 6, 2020, 8:48 PM

#

I wouldn't use state machine for anything

nimble hatch Feb 6, 2020, 8:48 PM

#

5 sets of animations, all unique, and none of the attacks optimized for a clean start -> next -> repeat loop

molten jewel Feb 6, 2020, 8:48 PM

#

If the question was to me

#

I make nodes for pretty much anything and everything to retain control over stuff

nimble hatch Feb 6, 2020, 8:48 PM

#

so how do I blend 3 attacks together smoothly?

#

I am all for no state machine if I can do that

molten jewel Feb 6, 2020, 8:48 PM

#

well

#

if you right click a play animation node

heavy needle Feb 6, 2020, 8:49 PM

#

like what animations are you useing? they are from a pack you said?

molten jewel Feb 6, 2020, 8:49 PM

#

you can convert it to a evaluate node

#

that way you pump in the actual time for the animation

#

and then you can use regular blend nodes to transition between the three as needed with a float you manually calculate on event graph

nimble hatch Feb 6, 2020, 8:50 PM

#

https://www.unrealengine.com/marketplace/en-US/product/modular-rpg-heroes-polyart

#

@molten jewel oof.. so you really mean do it all by hand lol

heavy needle Feb 6, 2020, 8:51 PM

#

but if you only problem is that your blending not back at the end, you maybe go back the the idle animation and then start the montage again.

#

because it will blend back from the montage to statemachine.

nimble hatch Feb 6, 2020, 8:51 PM

#

that was a thought, and I tried it, but the problem is I didnt want to do that lol

#

i transition based on attack boolean and I would have to say stop the boolean from being true, delay, then turn it back on (auto attacking)

#

I was working on looking into that but wanted to figure it out a better way

molten jewel Feb 6, 2020, 8:53 PM

#

I really do

📎 unknown.png

nimble hatch Feb 6, 2020, 8:53 PM

#

so Idle idle idle (auto attack on) -> attack 1 -> attack 2 -> attack 3 -> idle (no animation plays as it goes right back to attack1)

molten jewel Feb 6, 2020, 8:53 PM

#

to me thats a lot less complicated than state machine

nimble hatch Feb 6, 2020, 8:54 PM

#

welp I will try that once I get this 11 blueprint system in place and see how it works lol 🙂

#

I've redone this lke 4 times so it's not like I cant do it by heart now

molten jewel Feb 6, 2020, 8:54 PM

#

haha hang in there

nimble hatch Feb 6, 2020, 8:54 PM

#

nah this is how I learn

molten jewel Feb 6, 2020, 8:56 PM

#

yeah, feel free to ping if you wanna try that route and run into issues. would recommend this setting for blend multi. only other thing that comes to mind as being annoying with that graph i just posted is times are in seconds instead of fractional

📎 unknown.png

nimble hatch Feb 6, 2020, 8:56 PM

#

damnit lol everytime I think I have this the engine is like nah uh here have some more crap

#

screw it, just going to duplicate variables all over the project whoo

molten jewel Feb 6, 2020, 8:56 PM

#

the less you deal with state machine the less unknown imo

#

haha yeah go for it

nimble hatch Feb 6, 2020, 8:57 PM

#

I wonder how much memory and perf cached pose uses up

molten jewel Feb 6, 2020, 8:58 PM

#

one transform for every bone in an array

#

and a curve descriptor for each curve

nimble hatch Feb 6, 2020, 8:58 PM

#

ahaha... crashed it damnit

molten jewel Feb 6, 2020, 8:58 PM

#

then memory for the table of names etc

#

oof.

#

cached pose is the only way to really reference a chain twice and have it evaluate once

#

so that difference, makes up for performance

#

using it once: meh

nimble hatch Feb 6, 2020, 8:59 PM

#

hey atleast I can reproduce the crash. Cant add an input pose subgraph into a linked layer animation state lol

heavy needle Feb 6, 2020, 8:59 PM

#

I took a look at the animations and it should work fine. frame 1 Animation 1 is the same as last frame animation 3

molten jewel Feb 6, 2020, 9:00 PM

#

darn haha

nimble hatch Feb 6, 2020, 9:00 PM

#

@heavy needle for which animations?

molten jewel Feb 6, 2020, 9:00 PM

#

i wonder if the input pose needs to be connected and evaluated prior to something else

heavy needle Feb 6, 2020, 9:00 PM

#

are you sure you using the correct ones? like there are root motion and in place ones

nimble hatch Feb 6, 2020, 9:00 PM

#

I am using the in place ones

heavy needle Feb 6, 2020, 9:00 PM

#

from this pack you linked.

nimble hatch Feb 6, 2020, 9:01 PM

#

yep, Combo01_SwordShieldAnim -> combo02 -> combo03 -> repeat

#

3 ends in a pierce, 1 starts with a back hand swing

heavy needle Feb 6, 2020, 9:01 PM

#

they are 5

#

you just add the other two ones and they go back to idle, the double sword ones have 3 animations

nimble hatch Feb 6, 2020, 9:02 PM

#

yep but we arent using all 5 😉

#

hence the need for blending

#

like I said using assets in the wrong way is not helping

#

but damnit this is guerilla game dev, we don't have resources to do it right

molten jewel Feb 6, 2020, 9:04 PM

#

may be able to fine tune them in editor but i'm not positive on how that works beyond just using sequence recorder to make an animation

#

lol yeah

nimble hatch Feb 6, 2020, 9:04 PM

#

yeah I could do that and had thought of that. add a few more frames and keyframe it back to the start but

heavy needle Feb 6, 2020, 9:04 PM

#

just use the 5 ones and done. like why making it complicated.

#

lol

molten jewel Feb 6, 2020, 9:05 PM

#

may allow the montage approach to work

nimble hatch Feb 6, 2020, 9:05 PM

#

just because I have a good set of assets doesn't mean someone else does or I will in the future. Learning to get it to do what I need is the goal

#

plus in this case I like the 3 swing combo

heavy needle Feb 6, 2020, 9:06 PM

#

you could edit the animation and set it back to the idle state.

molten jewel Feb 6, 2020, 9:06 PM

#

i think 3 is the right number of attacks anyways

#

must check what streets of rage does

#

jab uppercut kick

nimble hatch Feb 6, 2020, 9:07 PM

#

Im using ESO as my example for this, and they generally have 2 animations for swings and it works fine

#

this is more along the lines of making what I have work for what I need which is what most people tend to run into

molten jewel Feb 6, 2020, 9:08 PM

#

you should definitely mention to use VectorLengthXY for speed from velocity

nimble hatch Feb 6, 2020, 9:08 PM

#

but epic doesn't do it that way, why should we 😛

molten jewel Feb 6, 2020, 9:09 PM

#

when epic turned that get direction node into a pure node, everyone looked to youtube on what to do with the green version instead of blue as the epic docs say. And the one video on youtube that talks about it tells people to use VectorLengthSquared instead.

#

So now all the people trying to learn animation blueprints that i see are using VectorLengthSquared

nimble hatch Feb 6, 2020, 9:10 PM

#

to the trial and error machine!

molten jewel Feb 6, 2020, 9:10 PM

#

lol yeah

#

well squared speed works for the one use of transition checking

#

so you tell someone, no thats wrong

#

and they are like: nah it works

#

but yeah, godspeed

nimble hatch Feb 6, 2020, 9:11 PM

#

lol

brazen canopy Feb 6, 2020, 9:18 PM

#

Hey all. Is there any tutorials or sample projects on using animation sharing plugin? Couldn't find any of those on the internet((
@brazen canopy

#

Bump((

nimble hatch Feb 6, 2020, 9:23 PM

#

cool, I will check it out! thanks

heavy needle Feb 6, 2020, 9:26 PM

#

no problem, was just copy paste.

upbeat comet Feb 6, 2020, 9:26 PM

#

@nimble hatch I never thought I'd see you out in the wild. Just wanted to say thanks for all the videos you make!! They really help 🙂

nimble hatch Feb 6, 2020, 9:35 PM

#

found a weird compromise to getting it to go back to idle for a tick, dont know why i didnt think of it before lol, I just added a new node between last attack and first to go back to idle for a small bit of time instead of sending it back to the actual entry idle node... duh

#

welp it's weird but it works. I can grab the current linked weapon or locomotion layer in the anim bp and unlink it then replace it with the one I want. technically I can now have different feet animations than weapon animations as well if I ever wanted that. I could see a good use for this now maybe i get a horse or something and then I just link in a static locomotion graph and bam done

molten jewel Feb 6, 2020, 11:15 PM

#

sounds like it works though 👍

nimble hatch Feb 6, 2020, 11:18 PM

#

so far so good. Only tested with 1 weapon set and 2 locomotions.

#

the bad part about all this work and discussion is none of this feels right. If I was programming I would accept it since multiple ways to the same goal but my brain won't let me accept it with this.

molten jewel Feb 6, 2020, 11:32 PM

#

I completely understand that feeling

#

the only point where anim bp works like that is when your dealing with the c++ part of it

#

I really wish there were more reusable features

#

that didn't require that i mean

hybrid ruin Feb 6, 2020, 11:45 PM

#

Uh

#

So I'm trying to export my blender animations to UE4 but after export they show up empty

#

Any ideas why?

Hiya, just wanted to say that I finally figured out my problem

#

It wasn't that they weren't there

#

Just that they were very very very small

#

Turns out the scaling in UE4 is VERY different from Blender

glad hearth Feb 7, 2020, 1:10 AM

#

@hybrid ruin I hate it when that happens lol, glad you were able to figure it out, I had no idea personally

hybrid ruin Feb 7, 2020, 1:11 AM

#

It's cool. If I knew what your problem was I'd help you out

#

But sadly I don't

no problem 👍

alright ill try that 👍

#

Just use Vector Length instead

@glad hearth did a tutorial tell you to use that squared node?

yeah by virtus the zelda game series episode 1

molten jewel Feb 7, 2020, 1:30 AM

we were literally just talking about that misinformation lol (using squared)

nimble hatch Feb 7, 2020, 1:31 AM

Would explain why I never had that issue I just use the third person template and it's set up already lol

#

Pretty sure the docs say non squared as well

because its not an exec anymore

#

its pure now

you'll see in the dm i sent

nimble hatch Feb 7, 2020, 1:35 AM

#

Huh. In bed or I would test lol.. makes sense tho I haven't used a 2d blendspace in a while

molten jewel Feb 7, 2020, 1:39 AM

#

yeah, the video says how to get it to come up but then says to use squared 🤷

nimble hatch Feb 7, 2020, 1:43 AM

#

Weird

#

There's an image from 2015 showing the pure version of that node so this must be waaaaaay wrong

#

Lol I wonder if they changed it to impure then back to pure

#

Watched that Zelda one I bet it's more due to virtus video than anything else due to his reach. He definitely uses vector length squared without any explanation

Hey guys. How would yall go about implementing attack speed ?? I want it to speed up the rate my montages are played. But the blends don't scale with play rate. So as my attack speed gets higher the blends go wonky and start ruining stuff.
Not sure of the best way around it. Tried looking in a few discords. Done a bunch of searching and can't seem to find an answer.

hollow tide Feb 7, 2020, 2:51 AM

#

I haven't tested this feature, but it sounds useful for your case. It's called Inertial Blending https://docs.unrealengine.com/en-US/Engine/Animation/NodeReference/Blend/index.html

Blend Nodes

Animation nodes that blend multiple animations together based on a set of criteria.

molten jewel Feb 7, 2020, 3:35 AM

#

Yeah thats definitely earlier than the one i'm thinking of mathew

weak jungle Feb 7, 2020, 3:50 AM

#

Unfortunately inertial blending is for anim graph only as far as I can see and doesn't take montages into account. It's just a shame the blend in and out of montages arnt dynamic and adjust with the play rate. Seems a bit odd to have them static like they are.

molten jewel Feb 7, 2020, 4:01 AM

yeah i believe its a state machine transition thing

I'm working on implementing some foot IK. I'd like to be able to blend the IK on/off based on the vertical distance the foot is from the ground plane in the source animation. I had the idea of baking out the ground plane offset in Maya into a animation curve in UE4. I'm assuming I'll need to develop my own tooling for this, but does anyone know if there's another way to do this?

molten jewel Feb 7, 2020, 5:28 PM

#

@boreal remnant would highly recommend not bothering with curves with footing

#

a thing i'll complain a lot of is people using last frame's data to do things in the current frame

#

its the only option with curves unless you are dealing with custom anim nodes specific to the curves

#

because you get curve values in event graph, its always going to be immediately prior to the frames animation determination (Animation Update) or after the determination (Post Update)

#

only way you can usefully utilize the curve data would be make a c++ node that does what you want to respond to it which operates after the curves are filled by animation normally. that is the only place you can modify the pose being made and also work with the same curve data in the frame

#

https://www.youtube.com/watch?v=IKbYxaV59gs a 'lightweight' approach to the thing is to match ik foot root to the normal of the movement capsule against the ground. i do use curves here to state if the foot is on the ground or not. at the end of the frame if the foot is on the ground and it was not on the ground in the previous frame i store that frames ik root position for that foot, then on the following frame if the foot was on the ground i lock the foot in place as if ik foot root didn't move from the previous frame, and that foots animation is ignored. its not ideal because if running faster than frame rate and i miss a foot up curve the foot gets stuck where it is. but just sharing this to give you more ideas. I don't think foot height to ground would be a good source of info to work with. but you could definitely figure out whatever solution that works for you

kind crown Feb 7, 2020, 6:05 PM

#

if I have a custom anim graph node, do I need to put the editor node class somewhere else than my normal game editor module?

#

doing that seems to break starting a standalone game through the editor with -game because the abp fails to load since it depends on the editor module which is not loaded

#

yet the normal nodes from AnimGraph module (also editor only) don't seem to cause any issues br_thinking

kind crown Feb 7, 2020, 6:41 PM

#

apparently my editor module needs to be type UncookedOnly rather than Editor for this to work

molten jewel Feb 7, 2020, 10:40 PM

yo @kind crown

#

I have been using the same loadphase for ever

#

for anim node modules.

kind crown Feb 7, 2020, 10:41 PM

kind crown Feb 7, 2020, 10:41 PM

#

oof why do you have dependencies in here

#

rather than in build.cs

molten jewel Feb 7, 2020, 10:42 PM

#

I recall having issues like what your running into, pre default for the structs and the editor node graphs works. I don't know how necessary they are to be there.

#

I probably don't need to

#

I just followed some dated wiki article advice

kind crown Feb 7, 2020, 10:43 PM

#

you ever try to start a standalone game through the editor? i.e. launch it with path/to/bla.uproject -game

molten jewel Feb 7, 2020, 10:43 PM

#

yep

kind crown Feb 7, 2020, 10:43 PM

#

yeah so that didn't work

#

because the bp depends on the editor node thing

#

and that module isn't loaded if it's type editor

molten jewel Feb 7, 2020, 10:44 PM

#

the graph is separate from the anim instance

#

the structs are stored in an array some how

kind crown Feb 7, 2020, 10:44 PM

#

I have no idea how it works

molten jewel Feb 7, 2020, 10:44 PM

#

its custom de/serialization i think

kind crown Feb 7, 2020, 10:45 PM

#

I just know it didn't work before and worked after I changed it to UncookedOnly

molten jewel Feb 7, 2020, 10:45 PM

Hmm i am not familiar with that at all

what does UncookedOnly mean

shy scarab Feb 7, 2020, 11:28 PM

#

Sorry if this is a noob question but I've tried googling several things to no avail. Just wondering if anyone knows how they might have done the animations in a game like mordhau?

From my understanding (haven't actually played it) the direction of the mouse movement controls the angle of the sword swing. So would this have been lots of different motion capture of various angles?
Or would they have gone for one animation and used some script to apply it to the direction of the mouse?

molten jewel Feb 7, 2020, 11:59 PM

#

There are really a lot of ways to go about it. I haven't played mordhau but in general if you can envision it working one way, it probably will work, you just might find it harder than you thought. But as you try it out you may run into a better or simpler solution, so its probably best to experiment.

I'm using runtime skeletal mesh merging - how can I avoid the visual glitch?

@molten jewel thanks mate

boreal remnant Feb 8, 2020, 7:04 AM

@molten jewel Thanks but I'm finding that I can't accurately get last frame bone position to determine velocity reliably - and some animations move the feet off the floor but the capsule is on the ground =/

jolly osprey Feb 8, 2020, 7:13 AM

#

I'm noticing that the "visual glitch" I was referring to earlier actually looks like sub meshes being collapsed for a frame or two

#

my ultimate call is to SetSkeletalMesh(BaseMesh, false), where false is being passed to bReinitPose. if I set it to true the glitching is gone but the running animation obviously gets reset which is not what I want

Hi everyone, I'm using 4.24.1. How do I activate the animation budget system? I followed the instructions in this link:

https://docs.unrealengine.com/en-US/Engine/Animation/AnimationBudgetAllocator/index.html

Animation Budget Allocator

System for constraining the time taken for animation data by dynamically throttling Skeletal Mesh Component ticking.

#

I enabled the plugin, closed and rebuilt the editor, then run a play in editor session and typed a.Budget.Enabled 1 in the console

#

But nothing happens, nor does anything happen if I type a.Budget.Debug.Enabled 1

#

No graph appears or anything

#

Ok sorry I managed to get it to work by messing around, seems like you have to call the "enable animation budget" blueprint function first, console command doesn't seem to work properly

#

However, even when I have 200 characters on screen, the graph just shows the budget as 1ms and the current workload at 0, so it seems like none of my meshes make use of it

#

With debug enabled I don't see the "HI, LO, I" marker on each mesh either

#

The documentation makes it seem like just by enabling the budgeter and leaving the values at default it will work

#

Does anyone know anything about this? I don't understand why none of my characters seem to be visible to the budgeting system

mellow urchin Feb 8, 2020, 4:46 PM

#

hey does anyone know where or how i can see the keyframes of my anim?

empty mural Feb 8, 2020, 5:09 PM

#

I think I'm going insane, it's been 5 hours since I started to understand how Unreal's animation system works but I'm still lost between the animations, poses, blend spaces, sequences and other anim bluprints. All I wanted was setting a different pose on my VR hand for each pickable objects, can someone give me a hint on where to look?

austere light Feb 8, 2020, 5:14 PM

#

@empty mural the way I do it is create an enum to describe how the object should be held, and then use a blend by node

#

For example, in my game we have various types of weapons: musket, pistol, sword and so on

#

So I have an enum which sets the type of weapon it is, and then in the animation blueprint i have a blend by node which has a different idle / run / aim animation depending on what enum value is set on the held weapon

empty mural Feb 8, 2020, 5:19 PM

#

hum, I would like to have a Pose variable on each object so that the artists can integrate their stuff without me having to maintain an enum, do you think that's possible?

austere light Feb 8, 2020, 5:20 PM

#

So that's what I have, a pose variable. Then the artists can integrate their animations for each pose and whenever you create a new object you just set the pose variable and it will all work

#

The pose variable is an enum in my case

#

So I have a drop down list on each inventory item from which I can pick the pose

#

And it will just work, if I take the pistol weapon and change the pose to "musket" then suddenly the guy will aim the pistol with two hands

empty mural Feb 8, 2020, 5:23 PM

#

That sounds like what I want, but there's still the "it will all work" part that I don't understand. I know what I want, but I don't know how to achieve it

austere light Feb 8, 2020, 5:24 PM

#

So step 1: define an enum which contains the different pose descriptions you want. They can be anything you like

#

Step 2: create the animations for each pose

empty mural Feb 8, 2020, 5:25 PM

#

where?

austere light Feb 8, 2020, 5:25 PM

#

Are you working in blueprints or C++?

empty mural Feb 8, 2020, 5:26 PM

#

blueprint first, so that I can iterate quickly

#

oh, you meant this?

📎 unknown.png

austere light Feb 8, 2020, 5:26 PM

#

Ok, so I think you right click in the content browser and go to Data, and then Enum to create a new enum. Open it up and add the relevant entries

#

Yeah that's it

#

Sorry I work in C++ so not familiar with blueprints

#

Create a new Enumeration and add the various entries which will describe each pose

empty mural Feb 8, 2020, 5:27 PM

#

ok, done

austere light Feb 8, 2020, 5:28 PM

#

Now in your base inventory object blueprint, define a new variable using your enum type

#

Make it public so you can reference it in the anim blueprint

#

Now, in the animation state machine, open whatever state you want to do animations in, and right click and search for the node called Blend By (Your enum name)

#

Get a reference to the inventory objects enum variable you declared, and plug it into the blend by node

empty mural Feb 8, 2020, 5:30 PM

#

ok so I think the problem's here, I don't have an animation state machine

austere light Feb 8, 2020, 5:30 PM

#

Ah

#

You can do it in the animation graph too

#

Dont have to have a state machine

empty mural Feb 8, 2020, 5:32 PM

#

I actually have nothing since my artists still have not done any animation. Can I create poses directly in Unreal?

austere light Feb 8, 2020, 5:32 PM

#

I don't think so, no. If you can use blender you could create some placeholder animations just so you can block everything out and then replace with proper animations after

empty mural Feb 8, 2020, 5:34 PM

#

I don't know blender either :/

#

I will try something and not bother you any longer, thanks a lot for your help!

I have tried recording an AI controlled character with the old recorder and the new Take Recorder (which is the preferred option) and both do not play back the recorded animation correctly unless I switch on 'Force Root Lock' on the recorded motion. This can get tedious, especially considering I'll have a hundred or so actors eventually recorded at once.

Is this expected?

anim exports have their quirks, not just in blender

slate olive Feb 10, 2020, 9:35 PM

#

what do i do with bone mapping containers?

pliant hawk Feb 10, 2020, 9:39 PM

#

when you import the mesh in UE4 you can set the mode to import as a not skeletal mesh

#

then you'll get one mesh per "element"

#

you can then also set an option to import the mesh as a single mesh

jolly osprey Feb 10, 2020, 9:44 PM

#

Out of curiosity, what orientation do you guys use when creating and importing skel meshes into ue4? back when I've started I'd used +Y as the fwd axis in Maya, imported the mesh into by applying a rotation of -90 on Z.

#

today I've read up on this b/c it seemed weird and from what I gather some people do it like me whereas others set X fwd in Maya and aren't applying an import rotation in ue4

#

also, +Y fwd in maya seems to be used b/c of all marketplace assets having +Y as fwd too

#

which seems to be incorrect in that it's a workaround but Epic's mannequin has +Y fwd too

#

so... what gives?

molten jewel Feb 10, 2020, 9:46 PM

#

y is flipped in blender

#

so face -y in blender is +y in ue4

#

+y is what ue4 expects going by the labeling of the viewports as front, left etc

#

if I create an arrow component it's going to be facing +X

molten jewel Feb 10, 2020, 9:47 PM

#

(trivial thing to correct anyways)

#

yeah

#

no

#

its weird

jolly osprey Feb 10, 2020, 9:47 PM

#

gah...

molten jewel Feb 10, 2020, 9:47 PM

#

mannequin in tps template

#

has a -90 rotation on the skeletal mesh component

#

(Z)

jolly osprey Feb 10, 2020, 9:48 PM

#

yes

slate olive Feb 10, 2020, 9:48 PM

@pliant hawk ah okay, I'm retargeting skeletons and animations and so how would I use it for that?

pliant hawk Feb 10, 2020, 9:49 PM

#

sorry I wasn't answering to you but to the one question above 😛

#

@molten jewel is this correct orientation for a skel mesh?

slate olive Feb 10, 2020, 9:49 PM

#

ah okay my bad lol

jolly osprey Feb 10, 2020, 9:49 PM

#

+X

#

ultimately, in ue4

#

after all the rotate magic's been done

#

or should I have them facing +Y

slate olive Feb 10, 2020, 10:19 PM

#

why does my skeleton/animation retarget come out looking like this even if I renamed the bones to match one another

white rampart Feb 10, 2020, 10:55 PM

#

I had the same thing happen. Apparently posing your mesh to better match the pose of the skeleton you're retargeting to can help. I think some skeletal meshes are just not compatible with retargeting. But I'm not positive on that.

#

I originally posted this in the wrong place so relocating here. If anyone knows if there is another setting (beyond the initial 'Import Morph Targets' with mesh) that I should be ticking to import morph targets/shape keys, or a reason why they might not import, please let me know, because my blender skelmesh just will not import the shape keys into unreal.

#

I've followed a number of videos step by step exactly, and it just never imports the shapekey.

slate olive Feb 10, 2020, 10:59 PM

#

@white rampart okay so I should just repose the model in someplace like blender and not parent the armature of model I want animations from?

white rampart Feb 10, 2020, 11:01 PM

#

The way that I did it. Whichever editor I used for actual retargeting, there was a way to rotate the bones to match the position of the other armature. It had 2 little windows one with the target armature and one with the retarget armature. I was able to rotate them from in there. But I ended up with similar results to what you have anyway.

slate olive Feb 10, 2020, 11:02 PM

#

ah okay

#

I might as well just start animating the models I was going to animate myself

white rampart Feb 10, 2020, 11:06 PM

#

I got the impression (because I'd done things exactly as the tutorials instructed) that it may just not be compatible with meshes that have too different of an armature or body shape. I'm not sure how it goes wrong like that.

craggy coral Feb 10, 2020, 11:23 PM

#

Does anyone here know if there is a good set of root motion animations for prone locomotion?

#

Like crawling around?

#

Can't find any on the marketplace

#

I assume you can find stuff like that on animation sites, but not sure which one to opt for

#

Any tips would be appreciated 🙂

white rampart Feb 10, 2020, 11:24 PM

#

Something llike Mixamo is what I've seen people use.

craggy coral Feb 10, 2020, 11:25 PM

#

Yeah, but I've heard there are many options, and mixamo might be one of the lower quality ones?

#

I'm very new to this though

#

hehe

#

they do have prone locomotion though

#

hm

white rampart Feb 10, 2020, 11:27 PM

#

My shapekey made in blender works perfectly in Blender. When I import it into Unreal, the morph target is not importing (import morph targets is ticked).... I can't find anything on this problem, I've done everything exactly like every demonstration. I'm totally confused how that is possible.

white rampart Feb 10, 2020, 11:48 PM

#

I see what the problem is now.... It won't import shape keys if there is a subdivision surface modifier active on it at export.

#

Which really sucks because Animating shape keys with the subdivision surface already applied does not look good at all.

#

(And it won't let you apply the subdivision surface after adding shape keys)

#

I have this custom anim node of mine that's indicated to be sitting on the fast path

#

is this still getting some sort of BP slowdown though?

#

my main concern is the use of quats in BP even if it's for the absolute simple task of piping an existing variable into a node input slot

#

ideally I'd like to be able to keep using quat input pins but if it's to the detriment of performance then I'll have to remove all the visual goodness that nodes offer

opal jackal Feb 11, 2020, 3:29 AM

#

Can you export a pose from blender as it's own mesh? I posed a character and want to import that pose into UE4 as a new mesh.

molten jewel Feb 11, 2020, 3:33 AM

#

@jolly osprey with orientation its not super important but take a look at the front view of the mesh

#

and left or right, if these match up then it'll be the same as mannequin

#

for the capsule the character mesh lives inside, x should be forward always

#

And if you see a bolt, this is the clearest indicator that its running threaded.

#

it should work with any type that doesn't have a non-trivial copy constructor

#

TIsPODType i think

jolly osprey Feb 11, 2020, 3:39 AM

#

the reason I'm keen on getting orientation "right" is b/c I'm having to add 90 deg to computed rotations when it's facing the Y axis

#

the only counterargument to that is all the marketplace character assets being Y forward

molten jewel Feb 11, 2020, 3:40 AM

#

glass believe me i know what you mean haha

#

I don't like that extra rotation either

jolly osprey Feb 11, 2020, 3:40 AM

#

you're doing it too??

#

jeeez!

#

this is nuts

molten jewel Feb 11, 2020, 3:41 AM

#

I did for the first person game

#

the animations were authored x forward

jolly osprey Feb 11, 2020, 3:41 AM

#

well. screw the marketplace, I guess it's more important that I don't deal with quirky rotations

#

esp when quats are involved... how do you even add 90 on Z to a quat ?:P

molten jewel Feb 11, 2020, 3:41 AM

#

90 around z

#

this would be

#

0,0,0.70710678118654752440084436210485,0.70710678118654752440084436210485

jolly osprey Feb 11, 2020, 3:42 AM

#

y thank u let me tattoo that on my forehead

molten jewel Feb 11, 2020, 3:42 AM

#

quats are axis.xyz * sin(angle/2),cos(angle/2)

jolly osprey Feb 11, 2020, 3:42 AM

#

would make a nifty tshirt this

molten jewel Feb 11, 2020, 3:43 AM

#

so 0,0,sin(45),cos(45)

#

is 90 around z

jolly osprey Feb 11, 2020, 3:43 AM

#

if I do ever end up getting marketplace char anim packs I'll just export them out to fbx and rotate once in maya and be done w/ it

molten jewel Feb 11, 2020, 3:44 AM

#

ye

jolly osprey Feb 11, 2020, 4:16 AM

#

actually

#

how do you limit the rotation of a quaternion to a single axis?

#

e.g. to Z only

#

rats he's gone

molten jewel Feb 11, 2020, 4:19 AM

#

i'm here

#

so x y z of the quat is the axis of rotation

#

multiplied by sin(angle/2)

#

is if you wanted only the z

#

you'd set x and y to zero, then normalize the quat

#

but

#

i don't believe thats a clean operation

jolly osprey Feb 11, 2020, 4:21 AM

b/c I'm losing the up vector or?..
