20 Time Update 07

Today I finished off the rectangular buildings; they all have their textures and materials (although I still need to set up a node system to make the "windows" glow).

Instead of painstakingly recoloring each building, I duplicated and resized the new one to fit each of the other buildings in the file.  I am fairly satisfied with the results, and I'll probably start work on the chutes (the various tube-things that lead from building to building) next week.
