I agree op. You have to be careful to make sure that the sculpt tool is using the scans that match the ethnicity… you can cycle through them with the move/sculpt tools until you get something plausible. I disagree with the first reply, you can’t just mr. potato head these things if you are going for something ethno-specific.
I personally wish there were more European looking models with classically proportioned features like large “puffy” eyelids, grecian profiles, etc. The trick I’ve been using on the eyes it to widen the upper eyelid with the controls on the sculpt tool. It gets you close but more scans are needed to create many “looks” right now.
The ability to change the forehead/nose/chin ratio would be greatly appreciated as well.
