Just a quick note: the subdivision that my part of the code does is, unfortunately, an all or nothing business right now. It doesn't have the ability to preserve creases and, if I remember right, it ignores smoothing groups, as well. Luxrender's subdivision on the other hand can preserve creases, but it will open up textures seams and actor boundaries because there was some trickery required in overcoming its limited mesh model.

I haven't looked at the changes between 0.7 and 0.8 yet, though. It's entirely possibly that we could do away with that trickery by now and simply use Luxrender's own subdivision.

-- I'm not mad at you, just Westphalian.
