Super application

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

Newest update broke my workflow

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

Realtime Animation option not showing even under Metahuman Animator

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

Crashes with IOS 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.

iPhone 12 Results

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
