Odd Eye issue - Solved

I think over my years using DS, eyes have always caused the most grief.  Here is another one!  Any idea why these artifacts are showing up in the eyes?  Turned off all eye morphs.  Am using a character head morph, but no issues on a new version of that same character.  It's G8F (I have no idea if its 8.1...)

    ...and yes I applied a G3F material, which may be the cause of the problem, but since applied G8F eyes, and it does not fix back, and not sure how to correct it?

    OK found a solution here

    Not sure why, but Render Settings -> Optimization - Instance Optmization = Speed

    that fixed it

    It's a poorly documented convenience feature dating back from the earlier days of Iray as a PBR renderer in Hollywood film production.

    Generally speaking, scenes involving instancing (think fields of trees or orcs standing in formation, etc) involve large camera shifts and objects being very distant from scene center. Therefore an API call to reset the mathematical scene center to whatever the currently active camera view is was added to what happens any time the instancing configuration option is changed in a scene.
