Regarding the rounded look to the walls - Poser tries to round everything, as it was designed originally for organic figures, but there's a fix for this - In UVMapper (or other compatible program), just choose the "split vertices" option, and Poser will treat the flat surfaces as flat. It adds a bit to the polygon counts, but works well.(UVMapper is available in commercial versions & free "classic" version at http://www.uvmapper.com/. Really easy to use. Another way to get light into a building in poser, is to select a light, and set the shadow intensity to 50% or so (using the dials), this makes that light penetrate objects dimly. You can also turn off shadows for objects (like the roof & walls), which will make them permit light sources through. Makes some scenes look a little odd, but it works. I'm excited by your project. I think you should take as much time as you need to get it to where you're happy with it. I really hope you have time to stay with it all the way, and I want to thank you for sharing your progress.
