When i use cell fracture or subdivision in blender with ridgid body physics. It explodes. How can this be solved?
I would first make sure all your RB objects and passive objects have their scale applied .... ctrl A ....scale.
I would also make sure each objects origin is set to geometry
ctrl..alt...shift C .... origin to geometry.
Posting a blend file would help to troubleshoot other issues that may be occuring.
