Converting PhysX convex hull to poly mesh.

Hello,
is there any way to convert PhysX convex hull of an object to poly mesh? I have a lot of paint effects converted to meshes in my scene (they are very heavy) and I need to make same simple objects to use it as proxys of those. I think it would be a fastest way to do it.

thanks

How about using the debug visualization feature for the convex shape?
