wut u were asking is if u can import an OBJ file and pretty much spary paint it in PS. u can modify texture maps in PS, or u can do it all in postwork, u cant spray paint a 3d object in any image editor. the mobius effect is easily done by rendering 2 images. the scene w/ the person in it, and another displayed in wireframe view. u then put them on seperate layers, and do a gradient in the transparency mask. that was how it was done, it wasnt done with textures.
