[ODE] Still Spheres Vs Trimesh at Triangle Edges

[kurimail]

Thanks for your answer!.

The problem is that spheres rolling over a trimesh jumps on every triangle
edge. I have a 4-hinged spheres car, and when a sphere rolls over every
triangle edge, a little jump occurs.

As i sad, decreasing cfm solved a little the problem, but not all.
