Animations play in editor but not in build, REAAALLY need some help

I've got a deadline coming up, so any feedback on this would be really appreciated, but the animations on my player model just aren't working in builds of the game, though they play fine in editor.

It does give an error: "Could not produce class with ID 1108"

Would anyone be able to point me in the right direction with any of this?
I'd have something to work with if the error had some documentation to go with, or if the editor and build were consistent with one another.

 

I'm not a coder so this might be 'duh' info.

It has something to do with YAML Class ID - PreviewAssetType

Hi, i'm wondering how you managed to do this.

class id 1108 is our internal animation clip that we create for all the previewer, so somehow your animation clip are instantiated as an internal animation clip which doesn't exist in the player, it an editor class only.

We already do have an issue logged like this
https://issuetracker.unity3d.com/is...180-error-pops-up-and-player-is-not-animating

the user managed to fix his issue like this:
I figured it out- all of the animations had the same name which was :
nothing at all. (Null name)

Could you confirm if it the same issue for you?

 

Dude I could kiss you right now. It was straight up that, yeah. I was using exported animations, which all had no name. Renaming them all sorted the problem.

Seriously thank you so much for taking the time to respond, you've made my week.

 

We are wondering how it did happen.

@Steve_Taylor Could you give us some repro steps on how you managed to have an exported animation with no name?
Are you using our internal model importer to import your animation?

 

I have the same error, but I don't know of any animations that are not playing.
(Maybe QA hasn't noticed yet)

Since the corresponding bug is closed with "Won't fix", please post the appropriate workaround steps.

Thanks in advance.

 

I have the same issue after switching from 2019.1.13 to 2019.2.3. I checked and none of the models have animations without a name. the error does not seem to affect the game and i cant find any animations that are missing or not playing. Engine stripping is disabled.
Any hint on finding the issue is appreciated.

same here

 

I had the same problem. The animations from the .fbx exported from Blender I was using were named, but marked as "Read Only".
"Solved" it by creating new animations, clicking the "Show Read Only Properties" from the animation window and copy>>pasting the key frames. Not optimal, but it is a workaround if you have just a few animations.
A robust solution is required though... did anyone make progress on this topic?

 

Hello,

@Mecanim-Dev I ran into the same problem. Animations are fine in the editor but not in the game. The problem is that the anim controller seems to be using the preview animation clip instead of the original one (like in the image). That's most likely happening because I create the anim controller programmatically like so:

Code (CSharp):

1. var controller = AnimatorController.CreateAnimatorControllerAtPath(controllerPath);
2. var baseLayer = controller.layers[0];
3. var rootStateMachine = baseLayer.stateMachine;
4. var pose = rootStateMachine.AddState(fileName);
5. pose.motion = AssetDatabase.LoadAllAssetsAtPath(assetPath).FirstOrDefault(x => x is Motion) as Motion;
6. baseLayer.stateMachine.defaultState = pose;

Hope it helps

 

For me it was lack of bone-weight normalisation which caused the animation not to work in the Android device, though it ran fine in the Editor:
