Well, one thing I have noticed is that, when you load up a preset atmosphere that is NOT GI or GR, and then go into the lighting settings tab in tha atno editor and make it GI or GR, the light gets darker and "fuller"... it's kind of hard to explain, but the shadows get darker, and the light gets not brighter, but changes color a bit and creates sharper contrasts. Hope this helps. -Zak
