To start texturing the floor of the scene, I used this tarmac texture from the cd as a base to work from
Heres a image of one of the wheels, the disc and the brake both come from the 3dtotal cd, along with the bump map for the tred. As you can see the tyre is split up into 3 sections on the model, they all use the same instanced shader in the 'surface' slot of the mental ray material. The Lume Metal Material (phong) may have to be unlocked before you can use it....
goto \3dsmax6\mentalray\include\lume.mi, open that in notepad and remove the tag "hidden"from that shader [or any of them]
I used the lume metal material for blurred reflections, which I used again on the rims and the brake disc with a mask for the dirty parts on the material where it doesnt reflect.
