Unreal released their free Live Link face app for facial motion capture using ARkit last week. I’ve pulled out all the data send and receive functionality which the documentation was pretty vague on in parts- using unreal, OSC, and TCP and also solved a bunch of problems with the default scene so you don’t have to. It’s not perfect, but hope it helps ya’ll do great mocap!
