Quote - In my opinion there is no such thing as conservation of anything, in Poser. The things which do matter are: prevention of overlighting, and proper/believabe balancing of components. In both cases it seriously matters whether Gamma Correction is applied (it might when available (PPro/P10), as it improves the believability / level of realism of the result but it seriously affects the balances as well).

I'm happy to go into the details behind this, but only when someone is interested.

Don't. You still have not acknowledged the material I gave you to read, and more specifically, that 100 + 100 does not equal 200 in sRGB brightness.

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)
