LipSync
LipSync drives an actor’s mouth shapes from an audio signal in real time, so characters appear to speak or sing along with whatever audio is playing. Unlike the older lip-sync that lived inside AI Voice Chat, this system is available on all platforms, including Android and Quest.
Added in 2024.9.
Enabling LipSync
- Turn LipSync on globally in Playback Options.
- For each actor that should move its mouth, open Facial Control and enable LipSync.
Both toggles are required: the global toggle controls whether the audio is analyzed at all; the per-actor toggle controls which actors react to it.
Pairing with Spatial Audio
LipSync pairs naturally with Spatial Audio — anchor the audio to an actor’s head and enable LipSync on that same actor, and the result reads as “this character is speaking.”
Pairing with AI Voice Chat
AI Voice Chat drives speech audio that the LipSync system can analyze the same way as music or video audio.
