Sorry I was posting in a hurry as I had guests coming. My last post was a cut-and-paste from another thread, where I was discussing the total illumination from 5 lights, each with a 50% gray for color, was not 5 * mid-gray, because those colors were anti-gamma corrected.

I should have edited that a little.

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)
