Platform Compatibility

VRChat

VRCFaceTracking

To use Baballonia with VRChat, you will need to use VRCFaceTracking with the VRCFT-Babble module.

1. Download and install the latest version of VRCFaceTracking from Steam.
2. Install the VRCFT-Babble module within VRCFaceTracking.
3. Use Baballonia to set the module mode (eyes, face or both). Restart VRCFaceTracking to see your changes.

More information can be found on the VRCFT Docs

VRC Native Eyelook

Alternatively, Baballonia also supports VRC Native Eyelook.

While this doesn't support lower face tracking, it supports (almost) all VRChat Avatars.

Resonite / ChilloutVR

Existing mods should be compatible with Baballonia's lower face tracking.
