I wanted to tell you all that I love the new "glossy lighting" feature- now its easy to see the difference between the inside and outside of a surface when you use the per-model clipping tool. Without it, I had a hard time getting a sense of depth when a surface was clipped. But with the improvement glossy lighting brings, I have begun to wonder if other improvements in coloring and lighting are in the works or are possible. For instance, I use radial coloring with a grey palette to help my students pick out tunnels and pockets in a surface, but a better method would ambient occlusion on-the-fly. I've seen it in the molvis program "Qutemol", though the program does little else. Alternatively, is it possible to change the quality of shadows enabled in the effects window? And on a separate note, is it possible to change the inside color of a surface (something like "ribinsidecolor" for surfaces?) Thanks Dan -- ____________________________ Daniel Gurnon, Ph. D.
