Well, it doesn't really. If you look at the flipped one it is still twice as dark. :-( It's something with the plants.....it's like they absorb light on the underside. I mean, I put a light right on top of it and it's still too dark. The answer I got from e-on was basically play with the ambient and add point lights. So I guess I'll try that, tho I don't really know what I'm doing there. it's just frustrating to have something not work. Gail
