I have an eye that has a transparent cornea as part of the eye. I would like to be able to view where the iris is on the eye without having to resort to render shading to help with the animation. The actual iris is another part of the mesh below the cornea thus doesn’t show up at all in the 3d viewport. Is there a way in cycles to color only part of the object in the 3d viewport. I know I can shade the material of the cornea, but it then turns the entire object that color in the material setting. Is there a way to shade just part of the object in the 3d viewport?
Here is a blend with the eye.
My actual character file is linked in to about 20 other files. So I"m looking for a quick way to be able to change the viewport only shading, not the eye itself.
