What are the gamma settings for your non-colour image maps: like bump, spec, displacement and transmaps? If you do use renderer GC (and why have PP2010, else??) they need to be set to 1 in the Texture Manager dialogue:

Or, you can use that changeGamma script in Menu -> Scripts -> MaterialMods and change them all in one fell swoop.

If you are using lights that were designed for pre-PP2010, your renders will look like poo. If you are using shaders on skin designed to overcome pre-PP2010 shortcomings, your renders will look like poo.

I have found that whilst in P7, I was doing a lot of fiddling with shaders and lights and stuff to get render to look decent, I'm finding that PP2010 requires a lot MORE fiddling, particularly with content that was developed for that P5 - P7 era.
