oh, and as i understand HDRI, it's basically a sphere around teh scene. bryce can fake it, but basically the image applied over the sphere has colors. like the gray of a balcony, etc. that is translated into gray, blue, red, etc. light. and it lights the scene without any need for external lighting sources. my understanding, anyway. haven't looked it up much because bryce can't handle it in its native format. drac
