When we scan their faces, why don't we scan their hair? Why not just have them come in with the hair you want and then scan the hair?

That's because what if you want to change their hairstyle? Or what if you want to take that hairstyle and then put it on somebody else later? Or you want to mix and match? You kind of get locked in if they have the hair. You can't adjust it from there.

And also just scanning hair, from my experience doing scanning at Naughty Dog, scanners do not like hair.

They don't, yeah.

Because it's all these little strands. Nothing has the fidelity really to capture all that.
