- Add some kind of support for VRM models (i.e. VRoid studio).
- Support FaceCap Wifi streaming for iPhone-based facial tracking.
- Add lip-syncing support, maybe something similar to uLipSync since that's used in VTube Studio.
- Add MeowFace tracking support
- Add VSeeFace tracking support
- Mediapipe Face tracking
- Use Unified Expressions as the standard for all face tracking
- Use XRFaceTracker as an interface for face tracker support. It's currently experimental and not provided through godot_cpp.
- Look at supporting ALVR tracking (alvr-org/ALVR#2461), talk to Grillo in nullptr about it later.
