Does it matter that much?? With the eyeball, it's pretty easy to know what you've changed and how it's gonna look, and with the forehead, you can tell what, you're doing there. You can always test in game for those parts as well.

That's okay, it's a pain to set up CSP's in 3dsmax anyway, and there's a lot of guesswork.
