When I do my eyes, I use the Sphere3D divided to the max, rotate it 90 on the X axis, after drawing it & applying the eye texture, I then use the “Tool / Modifiers / Texture / TXR>COL” to color the polys, then I can remove the texture. I select the “ToyPlastic” Material, then I use the “Fill Object” with only the “Draw / M” button selected so as to fill the object with Material only, that way I can use the GelShaderA material to paint over top of the ToyPlastic material on the cornea.
I’m sure your aware of all this information, I thought I’d throw it your way just in case???
Let me know what you think & have a good one . . . Mark.
