I'm trying to adapt the excellent Design 7-9 sets from i13 for use with gamma correction in Poser Pro 2012, and I could use some help/advice please.

First, here is a render using the default values and sample scene the Design 9 package ships with, with GC turned off:

Here's what I get when I turn on GC, remove AO from the lights, and set gamma 1 on the transparency maps:

Everything became much darker and lifeless. (Please ignore the weird polygons. I've accidently set 'smooth polygons' and it did not like it...)

Now then I've looked at the materials. I could not find much that seemed suspicious... The only thing was the 'Reflection_lite_mult'. I've read somewhere that it should always be turned off, so I've tried that. Here's the result:

Not much better :(

I haven't changed the light intensities yet, as I wanted to be sure I'm not missing something.

Here are the texture gammas I've changed, and my render settings for the GC enabled images:

My main aim here is trying to learn how to adapt purchased content to GC...

I'd geatly appreciate some advice/ideas regarding what I should be look at next!
