Even when limited to box collisions, trimeshes are not all that stable. It 
mostly depends on the spacing of triangles. If there are few triangles the 
results are quite good, but with higher density meshes (e.g. terrain) the 
collider creates too many and often times conflicting contacts that break 
the solver.
