Wow, uh, yeah. I'd know those presets anywhere. Probably still not enough to please the contrarians, but it's certainly enough to convince me.

Generally speaking, the devs use eyeshadow like stage/film makeup. It's not supposed to be noticeable, just a way of slightly adjusting the perceived shape and position of the eyes. My own character, seen at left, has some for the same reason.

Enigma G'raha probably doesn't need any because he has a full custom face texture, which would mean they've likely baked it to onto the base texture.
