Epic Games is out with an update today that sees the launch of a new iOS app for game developers to improve virtual production. The Live Link Face app for iPhone and iPad lets game devs capture facial expressions in real-time and see them applied live to characters in Unreal Engine.

Epic Games announced the news in a blog post today (via MacStories). The Live Link Face app makes use of Apple’s ARKit as well as the TrueDepth front-facing cameras on iPhone and iPad.

Epic Games says the app is very versatile and can be useful for everything from large virtual productions to “a single artist’s desk” making it a valuable tool for those just getting started all the way up to veteran game studios.

Link Link Face app for iPhone and iPad is available now as a free download. Read more about using the app in Epic Games’ support documents here.

Back in May, Epic also showed off its upcoming Unreal Engine 5 that will bring some impressive new technologies and be compatible with Mac and iOS.
