Somewhere, very recently, someone posted a basic room as a freebie....but I'm not sure where (and I'm blaming that on the painkillers I'm taking right now ;). Maybe someone else remembers...LD perhaps? I made my own basic room set out of a couple of Spanki's floor props, which use tiling textures beautifully, and saved it to Basic Props. When I need a wall with a door or window, I add a basic morphing one that I think I got free from Joe Kurz's site. There are a couple of pre-made windows available too, that can be set into the wall.
