Live Link Face vs psai

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.

psai® is an interactive music engine for videogames, aimed at composers and developers creating adaptive soundtracks. Its playback logic can change intensity, recombine musical segments, pause, and respond to gameplay. The Unity edition is written in C# without native code, and the maker says it works on all Unity target platforms. The native C++ SDK is limited to Windows, with evaluation or licensing inquiries directed to the maker. The regular and Pro editions use the same Unity engine; Pro adds the standalone editor for creating projects from scratch. That editor is listed for Win/Mac and requires Music Engine Pro and Pro User Registration. Downloads include a demo soundtrack and eight free music themes. The maker says Unity use across a customer's projects has no further costs or royalties, with one copy required per company seat. However, the editor EULA limits users who have not purchased the engine through the Unity Asset Store to non-commercial editor use, including testing for future commercial use. The site also links to manuals, API documentation, tutorials, and a Unity forum.
