no.. I'm working with poser 4. I was messing with the material properties under the render tab. Hmmm... No easy way.. I know in other programs you can have a two sided "square" like 2d box and set opposite sides to different properties.. but... no such luck in poser. It's getting pretty complicated and I'm wondering if I should just abort creating this office building in poser and use a different program? Brian I'll IM you...
