I have to recommend to you :
Those two blogs are fully dedicated to car driving simulations, races and creation of tracks for best games in the world.
BaS Textures is main provider of textures for Rally of Magnolia,
so you can check how the textures are looking and see if you like them or not.
If you do I will be more than happy to show you how I did them, and teach you how to do them yourself.
BaS Design is responsible for logos and picture manipulation that I've mentioned earlier and it would be a separate department in this Blog.
