What Is This Black Sclera Business

Greybro

I can take any of my preconfigured characters and load them into a blank scene and they might render fine but on some of the larger(heavier) sets, the black eyescleras start to plague my renders.

 

Can anyone shed some light on this pleae.

Regards,
Brent

Wrong UV map? Are you using G8 materials on a G8.1, or vice versa?

Go into your Render Settings and change the Instancing Optimization to something else. It is not important whether it is Speed or Memory for this issue. It is the act of changing it that makes Iray recompute some stuff. That alone is usually enough to solve this problem.

barbult, that did not work. 

TheMysteryIsThePoint, I've tried several different characters in this particular scene so it's definitely the correct maps.

There are some other suggestions in this thread. Maybe the Eye Moisture refraction suggestion will help.
