var smoothSphereCollisions : boolean

Description

Uses interpolated normals for sphere collisions instead of flat polygonal normals.

This smoothes out bumps for sphere's rolling over smooth surfaces. The downside is that rolling over steep corners can behave really strangely and appears like it is pulling the sphere in some direction.
