## What is 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.
- Review captured footage on-device.

### 5/5 — External mic

*2026-07-13*

I love and appreciate this app. Minor issue: External mics used to be recognized but not anymore.

### 1/5 — Update broke audio

*2026-07-07*

The most recent update broke audio input and now I can’t record audio with anything other than the iPhone front microphone. Completely unusable for things like DJI, headphones, or any other audio types

### 3/5 — Super application

*2026-06-27*

Vivement la prise en charge du corps de façon natif sans passer par l’ordinateur

### 1/5 — Newest update broke my workflow

*2026-06-26*

I use unreal 5.4.4 and all the new footage is skewed and no longer works. Please fix this soon.

### 1/5 — Realtime Animation option not showing even under Metahuman Animator

*2026-06-04*

it was work from last update and with newest update it’s not working…

### 2/5 — Crashes with IOS 26

*2026-04-26*

Live Link Face was an essential part of my Unreal Engine live performance streaming setup, but after updating to iOS 26 the app is no longer usable (the app worked perfectly on IOS 18). I have attempted to use the app on multiple devices and constantly get the same issue. It crashes during use and has completely broken my real-time face tracking workflow. The crash happens after 10-15minutes of use. 

This app is not just a casual tool for me, it is part of a production pipeline for live performance and character animation. It worked before the iOS update, so this appears to be an iOS 26 compatibility issue that needs attention from Epic. I am unsure if this happens on the metahuman side of the app, I do not use metahuman.

Please release a fix as soon as possible. I regret updating our iPhones to IOS 26, and there is no way to roll back. I would gladly update this review once the app is stable again, because when it works, it is one of the cleanest ways to get facial motion capture into Unreal Engine.

### 5/5 — iPhone 12 Results

*2026-04-14*

iPhone 12 is the oldest phone to support this app and it shows. It can send tracking data for real-time capture at 30 fps. 60fps only lasts for a several minutes before throttling due to heat. At 30 fps it gets very hot but is okay if you turn the phone’s brightness all the way down, and remove any case you have one on it, and use a low watt (5w) charger

### 1/5 — Not working

*2026-04-01*

Can’t connect to Pc

### 5/5 — 受遮挡和光线影响抖动大

*2026-03-15*

建议增加后置摄像头人脸变焦识别功能

### 1/5 — This doesn’t work

*2026-02-25*

I have tried everything, keep getting missing data when trying to use depth feature. I have iPhone 12 Pro Max which should work.
