In looking at the motorcycle you indicated, I would suspect that the artist (Slouchcorp) used a type of wireframe render which in not available in RDS/Carrara. In RDS, and probably in Carrara, objects are transparent when rendered in wireframe. This allows the mesh on the reverse side of the object to show through (very confusing to the eye). You could probably approximate Slouchcorp's results by applying a texturemap composed of black lines on a white background and then inverting the color of the rendered image. This would produce a black object with white lines and white shadows. Good luck, Jim Zipperer a.k.a. Julian Boolean
