I have recently completed a project, which involved creating a dirt car for use within rFactor.

I have attached a couple of images of it running in game. By the way the track and surrounds have nothing to do with me.
I have also created a High Poly version (which I used to bake my normal maps etc from) and applied some materials to it and rendered it out using V-Ray, this can be viewed on my blog if anyone is interested.
