Real-time, offline, and cross-platform lip sync for MetaHuman and custom characters. Animate character lips in response to audio from various sources.
See the quality of real-time lip sync animation produced by the plugin. These animations can be applied to any supported character, whether it's MetaHuman or a custom character.
Runtime MetaHuman Lip Sync provides a comprehensive system for dynamic lip sync animation, enabling characters to speak naturally in response to audio input from various sources. Despite its name, the plugin works with a wide range of characters beyond just MetaHumans.
Generate lip sync animations in real-time from microphone input or pre-recorded audio
Works with MetaHuman, Daz Genesis 8/9, Reallusion CC3/CC4, Mixamo, ReadyPlayerMe, and more
Supports FACS-based systems, Apple ARKit, Preston Blair phoneme sets, and 3ds Max phoneme systems
Process audio from microphones, imported files, text-to-speech, or any PCM audio data
Set up lip sync animation with just a few Blueprint nodes. The plugin provides a clean, easy-to-use interface for implementing lip sync in your characters.
Integrate lip sync into your character's animation blueprint with the dedicated blending nodes.
Fine-tune the lip sync behavior with adjustable parameters for interpolation speed and reset timing.
Controls how quickly lip movements transition between visemes. Higher values result in more abrupt transitions.
The duration in seconds after which lip sync is reset when audio stops, preventing lingering mouth positions.
The plugin uses a standard set of visemes (visual phonemes) that are mapped to your character's morph targets:
Audio data is received as float PCM format with specified channels and sample rate
The plugin processes the audio to generate visemes (phonemes)
Visemes drive the lip sync animation using the character's pose asset
The animation is applied to the character in real-time
