How does one make fireflies on the eyeball go away?

    Just tested with the Cornea "Cutout Transparency" turned all the way off, still got the milky sort of issue.  So not thinking it's the Cornea at this point.

    Specularity on the pupil perhaps? Be sure that it is a flat black with no gloss/specularity/anything. In fact I would check to make sure there was no specularity/gloss on the iris as well. It is covered by the cornea and so it wouldn't have any of those properties itself. Also be sure that you have the cornea morph on so that it bulges out like a real eye does.

    Got it figured out.  Was working my ways back up the list, turning whites to black and rendering, turning off this and rendering, turning off that and rendering and then Ctrl Z and setting them back to the original settings and colors.  Then I got up to the Translucency Weight, which was set to about 50.  Set it to 0 and rendered.  Perfect Iris now.  All the hilights are still in tact but that milky cast on it is now gone.

    And if I'm not mistaken, a lot of the 'unfinished' character of the render/fireflies, too.

    Also, does she come with a Cornea Bulge morph?  If so, that should be dialed in to get the eyes to look right.

    Not sure about the bulge morph to be honest.  I rarely mess around with eyeball morphs.

    If you're using Iray, try applying the thin water iray shader to the cornea. Get all image maps out of the cornea surface settings. Sometimes people will put the eye texture map in there, it can mess things up.

    As mentioned before, there shouldn't be reflections/gloss on your pupil and iris surfaces, so turn off any glossiness and/or top coat on those. You can try changing the index of refraction (IOR) on the pupil to something like water as well.

    See if there are is a cornea bulge and/or iris correction morph and use them. They make a big difference.

    I haven't settled on a sclera shader I'm happy with yet. I assume that's the "eye" surface you were talking about. You could try a white marble iray shader there to start and then mess around with putting your diffuse/bump/normal map in.

    Well there's a lot of reflection there, but it also looks like maybe there's some really serious bump going on?
