Hi! Is trimesh-trimesh collision possible to do using ODE? I am trying to write a small game engine using C#, Managed DirectX and ODE.net and my trimesh-trimesh collision is behaving very strange. When intersecting with other objects the meshes start to jump around and the CPU usage goes up to 100%. I have basic geometry objects (boxes, spheres...) beautifully colliding with trimesh objects, but trimesh-trimesh collision seems a bit hard to implement. Searching the net I found that other people are having problems with this too, and that it is generally not recommended. However, it´s so easy to convert a .x-file to a trimesh, I would really like to implement trimesh collision. Should I implement my mesh collision som other way? Thanks! //chinc

ODE Trimesh-Trimesh is very flaky.

Most ODE users make their terrain as a Trimesh and everything else is composed of primitives.
