OK I loaded one of my rooms around him, but I did not set any materials. So all parts of the room are over reflective because Diffuse_Color =white and Diffuse_Value = 1.

There is a bit more fill lighting from the room on his face. I've lost some of the drama.

My initial setup was intentionally a void, as if the studio was painted black, so you have total control. Introduce a room, and you don't have total control. Well, not total direct control. You have to understand IDL a lot more to know what to do with the floor color, the ceiling, etc. I wasn't going to post tutorials on that level of detail until the rendering artifacts are solved. I simply don't want to bother with fine tuning something that may change in ... well a relatively short time interval that I cannot say in public.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
