Yeah, of course I'm trying to avoid switching workflows… (8^\ I think what I will try next is to see how hard it might be to use my original mesh as a reference in ModelBuilder and make a new one from scratch.

That would be really nice. Maybe, with The Foundry's purchase of Luxology, some of Modo's modeling tools will make their way into Nuke.
