I've finally made the leap into the Genesis characters with Cassie from 3D-Arena. I just couldn't resist that sweet smile. I loaded the base G8F, applied Josie 8, then Cassie texture and morphs. I'm rendering in Iray and found her to render to a nice chocolate brown. I double checked and yes, she is a Caucasian character with a fair complexion. I double checked all settings and what I had loaded, then loaded the base G8F and Josie 8. Then, just to be sure I loaded a couple of my good old Vicky Four figures. Everybody had Iray shaders applied. Sure enough, they rendered as expected with the exception of Cassie who again looked like a chocolate bar; a very nice chocolate bar mind you, but still a rich dark brown. Wad I screw up? Thanks for any suggestions.

Sounds like you don't have enough light.
