I assume this is Poser 7 then with no render GC?

The use of anti-gamma is to convert your textures to linear space. All well and good, but if you don't GC at the end, you'll have a very dark render.

Here's the summary:

• Traditional render - no antiGC, no GC - bright things look close to normal, darker things look nearly black
  * Anti GC only, no final GC - bright things look dark, dark things look totally black
  * Anti GC + final GC - bright things look bright, dark things look dark

Anti-gamma on the incoming materials should only be done if you're going to GC at the end. You could do it in post, or in the materials where you need/want it.

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)
