I've been trying to experiment with using ambience to illuminate a scene with very poor results. At first I didn't think it was working at all but when I brought my sphere (which I'm using as my ambient light source) very close to my subject and zoomed right in there was some very slight illumination. I have ambience set at 100 and white all other surface attributes off. If I could turn ambience up to 1000 or something I think it would work but if I enter a figure over 100 it isn't accepted. Is there any way to enter a higher value? - Baz
