Slow and steady.Still a ways to go, but getting there. Turned off the hair to speed up render.
As I experiment with this, I've come to the conclusion that the backface-culling technique for generating lines (the one used on RWBY) just doesn't look as nice as post-processed ones. It's probably(?) more reliable, but not nearly as pretty. It does, however, work great for realtime graphics, so I'm surprised we don't see as many cell-shaded games these days.
