[B]Texture/Shaders for NURBS, how do you make them????[/B]

[stickdude]

Hey, i was just wonderin how you can make textures/shaders for NURBS geometry, because i am making a car and I don't wanna convert to Polygons for UV mapping. So is there any way you can accurately texture NURBS, i know it's possible because it is done in this tut.

any tutorials, sites, resources, etc appreciated!! ;)
thanx
