Bright white lower eyelids

in Technical Help (nuts n bolts)

The lower eyelids of this Genesis 8 model are rendering bright white. I don't recall changing anything in the eyes except the iris color and the direction they are pointing.

 

Are the lower eyelids part of the eye socket? Does something have to be adjusted? (base color, for example??). Or are the lower eyelids part of something else? Can they be accessed individually?

Or is there something else that might be causing this?

    Could you show a larger render? It's hard to see what you mean.

    Looks like the Eye Moisture surface of the Eyelashes. Check that the Refraction Weight is 1.00, and Refraction Index 1.33 (or whatever tears are).

    I checked the settings and they were at RW 1 and R Index 1.30, which is pretty much what you recommend. I notice the Refaction Color setting right under those is white. I'll try adjusting that and see if it makes a difference.

    I only did a rough render, but adjusting the Refraction Color (for eye moisture) didn't seem to change anything. There are a lot of settings, it could take hours to try them all.

    I'm assuming the setting for the eyeball is the Sclera setting, but what about the eyelid? Is it considered part of the Eye Socket (as far as Genesis models go)?

    Is it possible the actual eyelid is set to white and is reflecting through the Eye Moisture? Or is the color of the eyelid controlled by the color of the face?

    It's definitely the eye moisture mentioned above causing the problem.  You might try adjusting the cutout opacity (I do this when I'm in a hurry), or try using one of the water shaders for Iray. Adjusting the translucency (increase) can sometimes help as well. The problem is you're getting too much reflection of the light on the surface, with little on no penetration on the light through the surface, and no visible light bouncing back from beneath the surface.

    Hope this helps.

    There is no "lower eyelid" material, as you've noticed. THe eyelids are all entirely included in the Face - and as her face isn't bright white, that's clearly not the problem. The Eye Socket is the little pink triangle at the corner of the eye, and the back of the eye - if you hide the eyes, you can see the eye socket.

    The quick way to ID which material is the problem is to go through each one and set the Cutout Opacity to 0 - when the white line goes away, that was the culprit.

    I understand the eye socket is the part that encloses the eye. My question was about how the model is constructed. Did the person designing/constructing it include the "shelf" part of the lower eyelid (where it transitions from the front part of the face, where the eyelashes attach, to where the eye socket begins) as part of the eye socket or as part of the face?

    From what you said, it sounds like it's part of the face. Does that mean the eye socket begins at the back of the eyelid "shelf"? It helps to know where the dividing line is for some of these parts.

     

    Dustrider, I tried increasing the translucency of the eye moisture (not a huge amount but enough that it should have made a difference) and I can't see a difference, but I will try the cutout opacity.

    In Genesis 8, the parts that make up the Eyes are the Cornea, Irises, Pupils, Sclera, and EyeMoisture (not to be confused with the EyeMoisture on the Eyelashes, a separate figure). The EyeSocket is part of the face, and all you can really see is the lacrimal in the corner. The rest of the EyeSocket lies entirely insidle the eyeball, a shortcut to have something to reflect off behind the pupil. The eyelids are part of the face, and the back side of the eyelid is part of the same group. The EyeSocket starts deep inside, about where the eyelid start.

    You can use the Geometry editor to highlight and/or hide the various parts. If you zoom in close enough, the viewport (in Texture-Shaded mode, at least) gives a cut-away view when the geometry passes behind the "camera" plane, and you can see a cross section of whatever you're looking at.

    Which character is this, anyway? It would be easier if we could use the same one.

    So you're confirming that the dividing line between the Face and the Eye Socket is the back edge of the eyelid. That's what seemed logical to me, but I wanted to be sure. Thanks.

    I didn't realize there were two Eye Moistures (one on the eyes and one on the eyelashes). So I turned the eyelashes off and the day-glow white line disappeared. So the problem occurs when I add the eyelashes. At least now I know where to look (I'll check Eye Moisture first).

     

    On a related topic... one thing I've noticed with almost all the models is the "shelf" of the eyelids (the distance between the eyelashes and the back of the eyelid) is too thin. The eyes in many of the renders look fake because the eyelashes are too close to the eyeball (they look like they are glued to the eyeball) instead of having the proper distance between the eyeball and the eyelashes.
