  1. I have PostProcess Animation blueprint where i change morph by using “Bone Driven Controller” node. It works. I rotate bone and morph (“Key 1”) changes and cube is scaled:

  2. But in physics assset (and on the scene) it doesnt work: bone is rotated but cube is not scaled.

Is this how it should be? Or maybe i missed something.
I think that AnimBP not know that physics is changing bones transform. Is it correct?
