DigitalHuman Eye Material distortion


I’m using the DigitalHuman project eye geometry and shaders in my own character. I notice that one of the eyes seems to be distorted incorrectly probably due to refraction. I’m not sure how to fix this eye. I only uniformly scaled the eyes slightly to fit my character and used the same shaders (left and right). If I adjust the refraction on off setting, I can get it to look correct without refraction, but then it does not look like a believable eye.

Also, I was curious as to how the occlusion and fader objects are intended to be rigged to move with the character. I’m using blendshapes for the head,
