Hi, I'm need some guidance on animated USD workflow.
I have to populate and animate a scene with hi poly USD.
As example think to a hi poly car that needs wheels animation.

I tried to create proxy, USD import it into SOP and animate it.
Then in LOP, reference the USD and and add the SOP animated transforms as sublayer. But only seams to work if the imported animation has the exact hi poly geometry as the one imported in LOPS. I cannot transfer the animation from animated low poly to rest hi poly. As works with RBD an rbdprocedurals node.

I attached a simple example without USD creation, but only HI static model and LO animated one. I polyreduce nodes are off, animation transfers ok, otherwise it doesn't.

Thanks.
