A rather complex(ish) material setup that allows you to provide flipbook based masks for facial features. (eyes, pupils, mouth, brows)
With some work you can easily add a nose feature or whatever you desire ofcourse.
This is mainly intended to be used along with blueprint/other animation related controls to change the eyes, emotion, movement over time.
It is probably far from a perfect setup, but should be a helpful learning tool or help you spark idea's on how to set one up yourself.

Should work on ue4 4.16 and up.
You can use this in commercial and non commercial products, ue4 marketplace content excluded. (This also goes for the material functions included in this package)
Mainly for learning purposes, so do not expect in-depth private help.
Textures are placeholders, you'll need to make your own.
Comes with a texturebaker tool.
