I have been in the middle of building a scene, and only today did I realize that my figures eyes were black. Well, just part of the eye anyway.

I have copied both the "EyeMoisture" and "Sclera" textures from the other figure (which renders correctly) but that does not fix the issue. I'm using DAZStudio 4.10 and V8.

Have you tried applying other eye textures?

I have. That's very strange, to me, that didn't work. That's why I tried copying and pasting textures from the other figure as I knew they were rendering correctly.

That happened to me once in Poser, but I reapplied eye textures to fix it.

The only issue with copying and pasting is it won't copy the shader base. So textures applied to channels that do not exist across shaders may not migrate. For example if you copy an Iray material and try to paste it on top of an 3DL shader base the results may not be what you expect.

You can check the shader type at the top of the surface tab, it will say something like Iray Uber or Daz Studio Default.

The best way to transfer material settings between figures is to save out a quick material preset which when applied will apply the shader, textures and all settings. Either that or make sure the same base shader is applied before copying and pasting.

Wouldn't reapplying the eye material from the library bypass that?

Yes it should as the shader settings are included.

The issue seems to be with the Sclera surface here, if you have a look in the surface tab check and make sure the shader type is for Iray/3DL depending on which engine you're going to render with. And also check the base color isn't set to black.

The base color is white, and I do see that Iray is the map type. I have applied different Iray eye textures, character skin maps, and even deleted the entire character and built a new one, but I always have the black eye during the render. So the second time I deleted the character I rendered it each time I added a new set of maps, clothing and hair and everything rendered great until I closed DAZ and reopened it later that day. At that point the black eyes returned.

Probably worth checking your log file to see if its throwing any errors. If you're not sure where to find it, it's Help/Troubleshooting/viewlogfile

There is also a thread here that may help.

Well, here's a new twist to the eye problem. Actually, it's very interesting. So, I've loaded new figures, new textures, new figure full body maps, etc., and had gotten the same problem. Then I stumbled on to something new. When I would first load the new figure and quick render the face, the eyes would render as they should, but when I closed DAZ and then re-opened it, and then render the face, the eyes would be black again. At this point I thought that it may just be V8, so I loaded G8 into the scene and placed V8 & G8 side by side and rendered them together. The eyes rendered fine so I closed the program, re-opened it and rendered them once again and the render was good. The only thing I hadn't done at this point is locate the figure to where she needed to be in the scene so I moved both figures to the required location and rendered both of them together, causing the black eyes to appear again. Then I moved V8 back to the zeroed location and rendered her face and the render was good. So it is the figures location on the set that determines the color of the eyes. What is causing this to happen?!? This is very strange to me!

Try changing lights. You may have a light casting a shadow on the eye when the figure is at that spot.

I believe their have been some reports in the past of this issue. Though most I have heard of were issues with pre Daz 4.9, what version are you using?

There are no shadows on the figure, just full sun. I had thought of that too, but the interesting thing is that the other figure is covered by a shadow but her eyes are fine when rendered.

I ran into the same problem, not only eyes, but strange black stripes across hair, it was driving me insane. It was a big set and my figures are very far away from the center. You are right! Once I moved my figures near the center, without changing anything else, all the stange black areas disappeared. Daz must not be designed to handle rendering very large sets. This happens on both 4.10 and 4.11.

If the Geness 8 Male figure is beyond "Z" from the center of the plane, the black appears. The further negative, the bigger black appear in the eyes. Try moving everything in the positive zone from the center of the plane, problem should be fixed. Position the figure at +0 thru infinity, not -1.
