Bone transforms of SDK3 avatar animation does not function properly in VRChat

I’m trying to implement an animation for a facial expression that affects bone transforms. The animation should affect bone rotation of the avatar’s ears. The blendshapes and bone rotations works correctly in Unity scene view as seen in the preview, but when uploaded to VRChat only the blendshapes work and not the bone rotations. Any ideas how to fix this?

resolved: i just needed to enable isAnimated property of the physbone script.
