VRChat plans to add native support for eye tracking.
The developers released a preview video running standalone on Quest Pro:
Both eye tracking and face tracking are already supported in Meta’s Horizon suite but aren’t yet in other 3rd party social platforms like Rec Room or Bigscreen.
Existing avatars with moving eyes should “just work” without changes. Initially both eyelids will be controlled together, so you’ll be able to blink but not wink, but winking is planned for a future SDK update.
