Autodesk MotionBuilder vs Live Link Face

Autodesk MotionBuilder is 3D character animation software for capturing, editing, and playing back complex animations. Its real-time character engine automatically creates movements for biped or human skeletons, while manipulation tools let users alter a character’s position and orientation. The listed capabilities include motion capture, motion retargeting, facial animation, animation retargeting, and character retargeting. Autodesk says professional animation and game studios use MotionBuilder to produce animations. It is designed to complement Maya and 3ds Max and exchanges data through Autodesk FBX with applications that support FBX. MotionBuilder is available for Linux and Windows. The stated minimum hardware includes a 64-bit Intel or AMD multi-core processor, 8 GB RAM, 4 GB of free disk space, and a three-button mouse. Autodesk offers a free 30-day trial, but no free plan. A subscription covers installation on up to three devices for one named user, with use limited to one computer at a time, and includes the current version plus three previous versions.

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.
