iray eyes issue

I am trying to render an image using the iray settings and my eyes are rendering like black pits. I've followed a few settings that people have posted that they use for their eyes, but I'm getting the same results. I am thinking it is texture issue, but before I started messing with iray settings, I was getting some eye color showing up, just not as vivid as they should be. Now they're simply black pits.
In pre-render mode, the eyes looked like they were just mesh shaded gray until I adjusted the roughness and I started seeing eye texture show up...but it doesn't change anything in the rendering stage, same result.

try replacing the cornea surface with the "water-thin" shader, then set the cutout opacity on the eye reflection surface to 0.See if that helps.
Is your scene empty? Try placing a large white cube/plane behind your camera to act as a reflector.
Let's back up a little bit more. What character is this? Some V4 textures, especially, are just too screwed up to use with Iray without a lot of experience and rework.
Try a render with Genesis or G2F, and see how that works. Be sure to apply at least the Daz Uber shader to all surfaces.
If you are using Iray Uber I have found that high values in the refraction roughness parameter will give this result with eyes. You can get away with using very low values for the parameter, which can be useful for slightly darkening eye colors that are too light... but generally it should be left at zero.
The problem is the eye surface material zone, it normally covers the entire eye and is used to pick up lighting highlights and reflections, depending on the Opacity setting or Iray Cutout Opacity setting then Iray is told not to render that surface, problem is that it can't see the other eye surfaces as a result and doesn't render them either, so you end up with black holes where the eyes should be.
As icecrmn suggests apply the Iray Water - Thin shader preset to the Cornea, eye surface and tear surface on your figure, the names of the surfaces vary depending on the figure.
turn refraction off
Wow, lots of good advice. I'm going to try them all. I know I did use the water/thin on the eyes and they went all white. But I'm new to this, so odds of me not know wth I was doing is pretty great :)
Please tell me how this can be done? How to apply Daz Uber shader to ALL surfaces?
Wrong...
Turning refraction 'off' is NOT going to fix anything, especially with a PBR. Setting the proper values for it will be a much better approach.
worked really well, thank you soooooooo much for this simple fix.
im having the same problem, but i dont know what a white cube thingy is. Can someone explain where to find this? What if i just put a light to hit on the actor?is it the same?
heres a pic, above is viewport below is how render comes out
To get the cube: Create > New Primitive > select Cube ...
Thank you Catherine!
