I have been working on a demo for a month now. It's not going well.
Codemasters very kindly supplied me a race track, but it was in max format. We grabbed a copy of max and tried to export the meshes as 3ds or wavefront obj files without success. The problem is with the materials, the codies have tied 3ds max into their development system so tightly that it uses the same shaders as the game does. Understandably they were not willing to give us their shaders, so we were stumped.
We got in touch with another company who put a GA on the task, he managed to re-texture the meshes, but when he tried to export them, the 3ds file was corrupt, and the wavefront obj file had duff texture coords and materials.
So back to square one.
I bought a race track from turbosquid, at first it looked ok, but when I looked in detail at the mesh a lot of the normals were facing the wrong way.
I'm not going to waste money buying another useless mesh, and I don't have the ability to go through 300,000 triangles checking each normal by hand.
So anyone have any ideas? This was supposed to be a 1 month project, 1 month later I still don't have a use-able race track mesh and my teddy bear has left the building.
