Getting back to the original question, textures are commonly set with a GC of 1.0 which is optimal for printing but not for viewing. Poser Pro's GC converts the texture GC of 1.0 to 2.2 which is optimal for a PC monitor. The Warorc texture may have been set to a GC of 2.2 using Photoshop which would give it a superior look back in the pre-Poser Pro days. There is a script that comes with Poser Pro -- the gamma correction script (Not at home, not sure where it sits)  -- where you can reduce the texture's GC (by -1.2) which, if what I suspect is true, will make it render correctly using Poser Pro's GC.
