Hi everyone,
I'm doing a RBD simulation with RBD packed obj. I used POP spin dop to get some spin and the result was strange.

They're not just spin, they fly away!
All setting is basic. I just add a POP spin dop.

So, how to make a correct spin?
Is there any idea, please.

With my friend's help I found the reason. It's just a simple mistake. The spin force should apply after bullet solver. And everything will work find.
