Here i load a tpose model through asset container and then instantiate it, and then try to load and clone the animation groups from another asset container.

This used to work in 4.2 but now is broken.

Switch between 4.2 and 5 to see

Any recommendations for fix?

I don’t quite know why it works in 4.2 because an animation loaded from a gltf/glb file must update the transform nodes, not the bones. So you should modify `return avatar.skeletons[0].bones[idx];` to `return avatar.skeletons[0].bones[idx].getTransformNode();`:

Amazing thank you! I don’t know why it worked before either, i thought the bones were transformnodes already? but looks like you need to get the node.

No, bones are not transform nodes (they inherit from `Node`, not `TransformNode`).

When loading a gltf/glb file, each bone of a skeleton is linked to a `TransformNode` (`bone.getTransformNode()` returns a non-null value) and it is this `TransformNode` which is animated, not the bone (but the bone still gets updated by the `TransformNode` matrix to mirror the transformation).
