Yo, I suddenly thought of something. I have an idea about implementing "real" tyres in my offroad simulator, as a cloth-like mesh with inside pressure. This mesh would then have to collide with the ground. But I remember reading somewhere that OPCODE don't work with deformable/dynamic meshes, is that right? And the tricollider use OPCODE, right? Hm. Problem, then. -- Amund Børsand <amund@c2i.net>
