noob question about collision inside hollow geo - ldotchopz - 03-07-2021
I have a shpere with a shell applied. i made it a physX shape and addded a physX collsion and set it to be the smaller inside sphere. so the outer shell would fall and hang off the inside sphere. i cannot get it to work. the hull doesn't see the outer spehere as a shell and bugs out and flys away.
It seems simple but maybe i'm missing something?
I have added scene file if that helps.

Maybe some setting with backfaces or double-sided?

You're trying to do dynamic concave collisions but that's not supported by PhysX. The solution is to break your shell apart and treat the individual parts as convex, and then bind them together. See the chain example in the official sample scenes.
