Sorry to cut out on you there Doc. I got yanked away last night. I have built the small wall using the reverse normals method. I can see where this method of filling in the back side is much more useful than the "Octabox" method as it would handle irregular or more organic shapes. The "Octabox" requires that the geometry of a prop be completely regular. I'm learning. Thanks for your help.
