Use Complex Collision as Simple wont simulate rigid body physics

So I changed my objects collision complexity to “Use complex collision as simple” (per poly collision), and it WONT simulate physics, is there any way in which i can use per poly collision and use physics rigid body simulations?

have anybody answered your question yet ? or have you got to solve the problem on your own ? because i’m facing the same issue here and I can’t find any help regarding it … Thanks in advance for your cooperation mate :wink:
