And we argue because it's the break between volumes, so we need something to do while we wait 'til August for the next episode.

@LiveandSound (to your first post) there are enough differences that I could disagree with that, yet there are enough similarities to say that it's possible they took the base Yang face model and did some editing to it. Hair-wise, yeah, most likely a palette swap. Face-wise, I'd say that it's more likely to be, as I said earlier, a slightly edited Yang face with palette swap. Not an exact clone, but pretty close.

Also, the little hair-sticking-up-thingy on Yang is also on Raven. So even if they looked entirely different, I'd say that's enough evidence to say their related. They don't have individual head models. The riggers mentioned as much.

They can swap hair and skin complextion, but that's as far as it goes. In order for Raven to be yang, they'd need to take a model in maya and redefine its dimensionsand also rerig it(since she'd need to lack yang's specific breast rigs)
