*Not sure if it is related, but I have found that some node setups expose entirely transparent layers above them. I have seen this with scalp and brow planes, though I have never dug deep enough to look for the cause. Perhaps it is AO?

I don't if your using the new poserpro renderer but I found out that the new gamma feature also affects the transparancy maps, by making them more transparant then what was meant to be.

Bopper.
