The material on this page refers to several different tools and functional areas of Unreal Engine. This page explains how to use the Live Link Face app to apply live performances on to the face of a 3D character, and how to make the resulting facial capture system work in the context of a full-scale production shoot. If your iOS device contains a depth camera and ARKit capabilities, you can use the free Live Link Face app from Epic Games to drive complex facial animations on 3D characters inside Unreal Engine, recording them live on your phone and in the engine. Recent models of the Apple iPhone and iPad offer sophisticated facial recognition and motion tracking capabilities that distinguish the position, topology, and movements of over 50 specific muscles in a user's face.
