WIP 9/29 - Bump

Here's the latest with the rendering today.  The background in supposed to have a bump on it, procedurally generated with a grid texture node, but for some reason nothing shows up.  I haven't figured it out yet and it is bugging me.  I have tried all sorts of things, and the tutorials online so far haven't been any help.  I need to figure this out because it is a very important tool.
Let me know what you think.

Still rough textures, work in progress
