In this video I’m showing how the Face Cap iOS App can be used for realtime facial animation, using the OSC plugin for Unreal Engine.
This is a valid, cheaper and easy to use alternative to the FaceAR Sample, and since a lot of people are struggling to deploy that to their iPhone, this app already give you what you want, without the need of having an Apple Developer account.
You just need to get the Index and the Blend Shape values, and from there you can use the data to drive your realtime character inside UE4.
