I think that I got my own car level working. I had to edit main.c, cg_add.c, and startup01.c programs. I deleted all of the 3D objects except the skybox and the buggy. I created a new terrain in MED, gave it a grass terrain, saved it, and placed it in my own car level. Is it possible to scale the grass texture so that the grass is "realistic" instead of blocky? I had problems trying to create a new skybox but I don't know how to create a new skybox the same way that the original skybox was created. If I run WED, load my own car level into WED, scope to the skybox, and check the "surfaces" tab, the texture is the default concrete block texture, not the sky with the mountains in the background. How do I create a new sky texture? I have to run my own car level from within SED, not WED. The original car level and my own car level worked properly. Car games created using the "Car Project" template in WED don't work properly because the buggy moves jerkily instead of smoothly. I think that there may be a bug in the "Car Project" template or that I didn't set up the buggy properly. How should I set up the buggy properly?
