Precompute Visemes to Save CPU Processing with Unreal

Updated: Sep 14, 2023

End-of-Life Notice for Oculus Spatializer Plugin

The Oculus Spatializer Plugin has been replaced by the Meta XR Audio SDK and is now in end-of-life stage. It will not receive any further support beyond v47. We strongly discourage its use. Please navigate to the Meta XR Audio SDK documentation for your specific engine:
- Meta XR Audio SDK for Unity Native
- Meta XR Audio SDK for FMOD and Unity
- Meta XR Audio SDK for Wwise and Unity
- Meta XR Audio SDK for Unreal Native
- Meta XR Audio SDK for FMOD and Unreal
- Meta XR Audio SDK for Wwise and Unreal

This documentation is no longer being updated and is subject for removal.

You can save a lot of processing power by pre-computing the visemes for recorded audio instead of generating the visemes in real-time. This is particularly useful for lip synced animations on non-playable characters or in mobile apps as there is less processing power available.

Generate the Visemes

To Generate LipSync Sequence:

Import an audio file to your Unreal project
Right click the audio file and choose Generate LipSyncSequence

The following image shows an example:

Apply the Visemes

Add an OVRLipSyncPlaybackActor component to your scene. The OVRLipSyncPlaybackActor works the same as an OVRLip Sync Actor component, but reads the visemes from a pre-computed sequence asset instead of generating them in real-time.
Set the sequence of the OVRLipSyncPlaybackActor to the previously precomputed lipsync asset. The following image shows an example:
