I'm confused why my prim groups get screwed up after assembling to packed primitives, I need to delete the inside groups of my fractured geometry after RBD sim. In the enclosed file I'm coloring the inside prim groups before and after they're converted to packed prims, what am I missing? thanks!

Fixed. The problem was that you were transferring groups in your assemble, which isn't necessary.

Interesting, that seems counter-intuitive. I wonder in what situations you would want to transfer groups when packing…

I think the groups are auto transferred, which is why they broke when you tried to manually transfer them.
