Animations don't work at runtime

Hello, I tried to import .glb character with animation, but it doesnt seem to work. It plays fine when I load it at runtime in the editor. But when I build it, the character is not animated. I tried it on Android, iOS and MacOS and neither of these worked. Only in the editor. Do you have a clue, what could I do wrong?

Thanks in advance for your response.

Here’s the code I use:

// Create new mesh.
AnimationClip[] animationClips;
GameObject result = Importer.LoadFromFile(itemFileInfo.FullName, new ImportSettings(), out animationClips);

// Setup animation, if there is any.
if (animationClips.Length > 0)
{
     Animator animatorComponent = result.gameObject.AddComponent<Animator>();
     AnimatorOverrideController gltfAnimatorOverride = new AnimatorOverrideController(gltfAnimator);

     for (int i = 0; i < animationClips.Length; ++i)
     {
          gltfAnimatorOverride["test"] = animationClips[i];
     }
     animatorComponent.runtimeAnimatorController = gltfAnimatorOverride;
}

I’m also attaching the .glb file: mixamo.glb.zip

Had the same issue on Android. I was getting error. “can’t use animatioclip set curve at runtime on non legacy animation clips”

Solved it by setting useLegacyClips to true on importSettings.

        AnimationClip[] animClips;
        var i = new ImportSettings();
        i.useLegacyClips = true;
        GameObject result = Importer.LoadFromFile(fileSavePath, i, out animClips);
        GameObject _wrapper = Instantiate(WrapperPrefab, pos, rot);

        if (animClips.Length > 0)
        {
            Animation anim = result.AddComponent<Animation>();
            animClips[0].legacy = true;
            anim.AddClip(animClips[0], animClips[0].name);
            anim.clip = anim.GetClip(animClips[0].name);
            anim.wrapMode = WrapMode.Loop;
            anim.Play();
        }

The Playables API doesn’t support legacy animation clips and GLTFUtility was failing to import non legacy clips at runtime, Unity was throwing this error: “Can’t use AnimationClip::SetCurve at Runtime on non Legacy AnimationClips”.

So now I’m using the the legacy Animation system, tested and working on iOS.

private void OnGLTFImportComplete(GameObject result, AnimationClip[] clips) {
        if (clips != null)
        {
            if (clips.Length > 0)
            {
                Animation animation = result.AddComponent<Animation>();
                animation.AddClip(clips[0], clips[0].name);
                animation.clip = animation.GetClip(clips[0].name);
                animation.Play();
                animation.wrapMode = WrapMode.Loop;
            }
        }
}
