Erm...

V2's eyeball material is the equivalent to V3's cornea, so shouldn't have any sort of texture attached to it.  You can use Alternate_Specular to add highlight effects, or the reflection channels for reflection effects but that's pretty much all you should do with it.  Eye textures should go on the relevant eye bits, such as Pupil, Eyewhite, Iris.

As a side note, I often feel like hunting down and shooting vendors who stick textures on the eyeball/cornea parts.  Yes, that includes reflection images, too.  Another pet hate is highlights and'or reflections on the pupil.  It's a hole in the eye, FFS!   It gets my goat no end to have to edit these fecking things manually.
