Looks like you have the figure surrounded by a white sphere and you have IDL enabled. Thus, the lighting is equivalent to the interior of a blast furnace at 10,000 degrees. You'd lose all shadows that way as well.

Get my light meter and render with that. It will show you when you're using too much light.

I am soon getting on a plane, so others can help you with that.

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)
