Everything to create ethnic morphs is already in the base figure. I even made a specific epicanthic fold morph (EyesAsian) so that Asian eyes would be easy. This is just 5 minutes of dialing some of the included dials, it can be refined much further and combined with the body handles, morph brush, etc.

(not a render, just a workspace screen capture)

This is why I don't understand the 'another Caucasian character' grumbling a few people posted. There are morphs to make other ethnicities and you can get a lot of skin tone variation by just tweaking the existing shaders and/or modifying the existing base texture in Photoshop and it's totally redistributable: so you could put the resulting character in freestuff or even sell it in the marketplace. In fact I'm totally baffled why nobody has done this already O_o

Miki was ok, my problem with her was SM blowing their entire figure dev budget on a baked 4' tall Asian character that you couldn't morph other ethnicities out of for a Poser market that is desperately starved for a pair of quality, flexible base figures.
