Unreal Engine's new Live Link Face app brings big-budget movie-style effects to the iPhone, with Face ID able to animate 3D characters in real time or capture face tracking data for later use.

The new Live Link Face iOS app is now available to download and use with the latest 4.25 release of Unreal Engine.

This data can be imported onto characters in Unreal Engine 4.25. The actual tracking leverages Apple's ARKit and an iOS device's TrueDepth front-facing camera.
