I can see that. Makes sense. I think I'm going to use a diffrent set of eye maps, since I only now remember I have better ones. The lighting color will probably need a tweek since I think the eyes picked up a lot of that blu-ish grey from the rim light. As for the occulusion, I work in two layers and combine them in photoshop as an overlay (one for an UberEnvironment2 render and one with normal lighting). I guess I'll just lower the intensity on the UE2 render and see if that sorts it out a bit.

Thanks for the advice everyone, I'll let you know how it turns out when I get a chance to make renders.
