I haven't found it easy to get the standard meshes to look "ethnic." A lot of "ethnic" morphs are basically like those old Hollywood movies: Caucasian faces with heavy eyeliner.

DAZ's ethnic morphs aren't bad...as long you don't mind the mannequin look. The ethnic morphs tend to look pretty bad if you want to give a face a real expression. They are still light-years better than CL's, though.

I really think that to get a truly realistic Asian or African face, that you can morph and give expression to, would require a different mesh.
