What's the best way to create a car texture which also 'renders' depth, shape and form? Initially, I had thought of painting the original blueprints, to match in 3-D eventually, but stretched textures would ruin it. I want to paint all the cuts, extrusions and hard/soft edges. I'd like a technique of faking depth and detail in the texturing stage itself. The software platform will be Blender (for 3-D) and Photoshop or GIMP for painting.
