Live Link Face vs Second Music System

Live Link Face captures facial performances and generates animation for MetaHuman characters in Unreal Engine. The iOS app supports real-time and processed animation and can capture raw video and depth data for the MetaHuman plugin. Epic describes the Android app as a beta for real-time MetaHuman facial animation. Animation streams over a network to Unreal Engine through the MetaHuman Live Link plugin; the phone and computer must be connected to a network. App settings include OSC connections for external controllers and devices. Android timecode can use the system clock, an NTP server, or a Tentacle Sync device for multi-device synchronization. Real-time Android animation is limited to certain Qualcomm chipsets, and Snapdragon 8s chipsets are unsupported; Android does not support capture for offline processing. Live Link Hub can download recorded media from Android and iOS devices and trigger recording on a connected phone. The app is free on iOS and Android. The App Store listing requires iOS 16 or later, while Epic’s workflow description specifies an iPhone 12 or later and a Windows 10/11 desktop PC.
