The MetaHumans from Epic Games have very complicated rigs which currently only work properly with Unreal Engine.

I went through the rig and extracted the necessary 52 face shapes that work with the ARkit, so I could better learn how these shapes are formed and recreate them on my own models in Maya or Blender.

There was quite a bit of work figuring all of this out, so I’m providing the FBX model of all 52 shapes so others can learn.

This model is intended for study purposes only. The head, teeth and eye models are included, along with the blendshapes and a test animation. Neither the body model, nor the textures are included.
