let me just clarify soemthing dilbert. I dont quite follow what you mean with deleting the nurbs dome and stitching. Do you mean literally delete the bottom faces of the dome and then putting a flat surface in there place so the car can sit on it?
I really want to get the clay render sorted as I love it how it appears as if there are no edges around the scene of walls etc.

PS, here is my first car that I want to clayify!

Any help on dirt shader in photoshop and how to draw them would be appreciated too, but my main priority is the clay render
