I'm rendering an image with mental ray materials and a daylight system (mr sky and my sun.) The image looks great just using the natural light and very realistic. However, in the areas where natural light doesn't reach I need to place articficial lights. I tried both the standard and the photometric lights and none of them renders no matter how much I adjust intensity or multiplier. It's as if those lights don't read at all. I've rendered with mental ray before using global illumination and final gathering and didn't have this problem.
Do you know why artificial lights wouldn't show?
Thanks a lot.
