Mike, Wyrwulf gives you a start. If you still get an effect of the cornea mesh in a render, even if it is not textured then: In UVMapper, you can select the material and assign it to a unique group, keep the material also, then maneuver with hide to name the left and right sides as different groups. Open the CR2 and add the new actors in all the necessary places, and duplicate the sections for the left and right eyes in the CR2 and make them for your new actors. Then you can use the Z trans dial to move the group out of your way. You loose all of your eye morphs, but this happens when your assign the material to a new group anyway.
