Don't bother going over to that forum (sorry I'm a tad bitter about them). I have tried for almost a year to ask this very question with little to no response and or solution. The only way to fix this is to get the object file to another app like Bryce 4 or 5 and import it in , delete the "cornea" object (the outer eye), export it from Bryce as a new obj file and then import it into Carrara. Hope that sheds some light. James
