Remember the .sliders command can be used to bring up sliders on the CBM to turn down the lighting of the terrain, the trees, and standard objects. I don't know, however, if that option is going to make it into the production version of AH3. If it is going to make it to production, then you probably should not try to fix it by toning down your skin art, but just allow the user to chose the lighting level he prefers via .sliders.
