Some sloppy committing on my part here which should be different commits. 1) Fixed the blue tint thing for the GUI icon using a gradient ramp as a tone map. This should come really close to whats in-game because the gradient points are based on eyedropper samples. So I have a mapping from V to HS for several V values.

Nilat sent me some FBX export fixes to some things after much careful research/testing on his part. I haven't had time to understand them yet but I'm just committing them anyway.
