Mick Gothic 2 - Black Eyes Bug

chapterhawk_276dcefd2e

Has anyone used the Mick Gothic 2 set? You can't render characters in IRAY in this set as they all have the black eyes bug.  I was careful to attempt the renders in the plus range for the X, Y and Z translates.  It makes no difference. I tried adding lots of additional lighting and nothing.  I take the same characters put them in any other scene and the eyes are great.  Put them into Mick Gothic 2 cathedral and the black eyes bug is back. Re-applying the eye presets does nothing.  I have tried 5 different characters to make sure it wasn't related to the individual model.  I'd love some advice from anyone who has overcome this issue.  Otherwise this amazing set is fairly useless.

Note: I have discovered that if you set the render settings to 'Sun-Sky Only' AND you use the Perspective View AND you zoom in super close to the eyes then it works minutely better, but is still unusable.  The eyes aren't completely black, but they are still very, very dark. I thought I would mention it to see if that sparks any thoughts.  For fun I tried putting a 50,000,000 lumens light right next to the character's face. The person looks almost pure white from top to bottom and the eyes are still black as night.  Tried using the Iray Ghost Light Kit to do an indirect diffuse light.  Still the same thing. Someone, somwhere must have put a character into this set before right?

If you go to the Editor tab of render Settings and look under Optimisation what is the path length setting? If it's not -1 check that it is at least 6 or so.

Thank you for your reply.  My setting was -1 on that option.  For fun I set it to 6, which unfortunately made no difference.  So, I reset it back to -1.  I appreciate the tip though.

Okay, I ran across an esoteric little bit of information. It mentioned that sometimes in a scene (for whatever reason) there is nothing for the inside of the eye to reflect off of.  Not sure why as the scene is indoors, but that's neither here nor there.  The person mentioned that you should make a 'plane' primitive and make the emission color white (1.00,1.00,1.00).  Then place the object a ways back behind your camera, making sure the surface area of the plane is "facing" the eyes of your character.  Out of desperation I tried it and wouldn't you know it?  It 100% fixed the problem.  It's a bit strange to have to do this and I really don't understand the IRAY physics behind it, but sure as heck it makes the eyes appear completely natural after doing it.  I hope this helps someone else out there.

If you have the lights to "scene only" you may try "dome and scene" to see if this fix things. Also make the dome visible.

Or you can use a 3DL dome just to be sure light rays bounce on something and don't get lost.
