LiveLink UE MoCap app for iPhone and iPad

Stream face animation from your IPhone / IPad into the Unreal Engine and let your 3D models get alive.

The Apple ARKit provides face tracking functionality on IOS devices with FaceID support. 51 blendshape values (relative movement values between 0->1) can be tapped and used for animating your own 3D faces.

On the other hand Unreal Engine provides a LiveLink interface, already prepared for receiving those ARKit blendshape values over UDP network protocol. And Unreal Engine includes ready to use controls and blueprint elements for integrating the values into your animation.

In this version 1.0 only the 51 known face blendshapes are transmitted. The Unreal Engine LiveLink API for ARKit supports 9 additional blendshape values, which express the relative transformation of the head. These currently not implemented blendshapes will be introduced in the next version.

Prerequesites:
- IOS device (IPhone / IPad) with FaceID support
