Eyes on V4.2 appear very dark on Iray

in New Users
Hi guys, I have a problem where V4.2's eyes and skin seems really off and the eyes especially is just black on renders. I dont have the problem on 3Delight, but is there a way to solve this?
I tried using the G2Essential Mat Iray, but it does not appear to be compatible with V4.2 and does not change anything on the render, here's the render.
Thank you for your help.

You will need to manually create an eye preset for V4/M4...I'm in the middle of a render, so I can't grab a surface list...but after it's finished I may be able to whip something up.
Same with the skin textures...
Here's a set up that should provide a good base for starting from...

It's a material preset using the Daz Iray Uber base and the V4 Lana textures for the eyes.
omg, thank you very much!!
