Live Link Face

Live Link Face for effortless facial animation in Unreal Engine—capture performances for use in Unreal Engine from your iPhone or iPad.

Capture facial performances for MetaHuman Animator:

- Live Link Face supports both real-time and processed animation.
- MetaHuman Animator uses Live Link Face to capture performances, then applies its own processing to create high-fidelity facial animation for MetaHumans.
- The Live Link Face app captures raw video and depth data, which can be transmitted directly from your device into Unreal Engine for use with the MetaHuman plugin.
- Facial animation created with MetaHuman Animator can be applied to any MetaHuman character in just a few clicks.
- This workflow requires an iPhone (12 or above) and a desktop PC running Windows 10/11.

Real-time animation for MetaHumans:

- The Live Link Face app generates animation to drive a MetaHuman Character in real time.
- Animation data is streamed to Unreal Engine over a network using the MetaHuman Live Link Plugin.
- This workflow requires an iPhone (12 or above) and a desktop PC running Windows 10/11.

Real-time animation for non-MetaHuman characters:

- Stream out ARKit animation data live to an Unreal Engine instance via Live Link over a network.
- Visualize facial expressions in real time with live rendering in Unreal Engine.
- Drive a 3D preview mesh, optionally overlaid over the video reference on the phone.
- Record the raw ARKit animation data and front-facing video reference footage.
- Tune the capture data to the individual performer and improve facial animation quality with rest pose calibration.

Timecode support for multi-device synchronization:

- Select from the system clock, an NTP server, or use a Tentacle Sync device to connect with a master clock on stage.
- Video reference is frame accurate with embedded timecode for editorial.

Control Live Link Face remotely with OSC or via the MetaHuman Plugin for Unreal Engine:

- Trigger recording remotely so actors can focus on their performances.
- Capture slate names and take numbers consistently.
- Extract data for processing and storage.

Browse and manage the library of captured takes:

- Delete takes within Live Link Face, share via AirDrop.
- Transfer directly over network when using MetaHuman Animator.
