I apologize for re-posting but I think my original query may have gotten lost in the "remove me" conservation.
I am wondering if there is a way to add a material/pattern to blocks? I have a room with a bathroom room in one corner. I have defined the bathroom using two blocks. I would like to "paint" the interior walls and blocks to match the architects color scheme. The Materials dialog allows for painting the interior walls, ceiling and floor but I don't see a way to change the color/texture of those blocks?
