static mesh actor and cloth mesh collision.(Physx 3.3.1)

I have a mesh of static avatar with about 100k triangles and like to achieve collision with cloth mesh.
I tried adding avatar mesh and cloth mesh in scene, but collision is not happening, this was working in Physx 2.8.x
As per document cloth should be set with collision sphere of actor but that limit is 32, is it must or just for performance?

Is there any way to achieve it?
