nikeboy72, I understood you never put your hands on 3D so far. So the best thing to do, is to take some really basic tutorials, to teach you what are 3D coordinates, vertices, edges, faces, meshes, etc. A nice place to start is the following collection :
Blender 3D: Noob to Pro - Wikibooks, collection of open-content textbooks.
For getting for your first pic to your second one, you'll know to learn two things :
- Model a car. In this case it's a really low poly model, meaning it's very simple.
- Texturing a car you previously modeled.
You'll find tutorials about both things in the link I wrote above.
Jason G, I don't know anything about rFactor. But if you are already used to putting cars into rFactor using another 3D package, my advice would be to use the large Blender exporting capabilities to bring to the other 3D package : it looks like there is (at least) one freely available 3ds->GMT file convertor. So use Blender to do the .blender -> 3ds step before.
