Thanks everyone. To try and answer several questions in one reply. Yes, I did make a different "Wall" material that had only one channel (Color) and hoped that it would be as matte and non-glossy as possible. It helped, but only slightly. (At first I didn't know what the "Paper" material did.
A also made a new "Luminous" material that had only a (Self Luminous) channel. as far as I could tell, that seemed no different in effect than the "No Shader" material. Yes, I also tried moving the self-luminous rectangle out of the hierarchy and put all the other scene objects into their own lever to which the GI material was applied. That didn't seem to change the lighting. I also tried what I had done in other software and rendered a separate "Reflection" channel with unexpected results. The Reflection-channel render seemed to show me the "reflectivity" of the materials in the scene, and not any actual reflection. (I have done this in C4D with good results for emphasizing a reflection in post-composting.) It also took me a while to figure out how to do this in RS. The only file format that seemed to support this was the native RS image format which I can only open with its viewer. But from the viewer I can not seem to separate and save the channels in any image format that is useful for compositing. I will try to post another comment with some images to show of some tests. Sorry about all the bother, Henry -- -- Henry Tjernlund http://www.renderosity.com/mod/gallery/browse.php?username=henrytj http://www.modelmayhem.com/HenryTjernlund http://imdb.com/name/nm2519729/ http://www.myspace.com/henrytj http://henrytj.deviantart.com/
