Companion App (Optional for Gameplay, Necessary for Facial Expressions)

Real Facial Expressions uses a companion app to track your facial expressions in real time.

Companion app can now receive tracking from VTube Studio!

With the companion app: Facial expressions are mirrored on your character using your webcam.

Without the companion app: You can still play the game normally, but facial animations will not be mirrored. Instead, the default Hytale idle animations will play.

Download the companion app here: Real Facial Expressions Companion App

Note: The companion app only transmits facial blendshape data and a derived eye look direction. No other video or image data ever leaves your PC.

Disclaimers

Real Facial Expressions uses a companion app to send data to the server. The connection fields are intended to remain private. Try not to leak them, or you will at least have to reset your faceId with /rfe resetFaceId
There will very likely be conflicts with other player animation plugins, particularly those that modify Server/Models/Human/Player.json.

Long Term Goals and Current Blockers

More animations. More animations. The primary blocker is the current state of Hytale’s animation system. From my understanding, Hytale does not support playing multiple animations within the same animation slot simultaneously. To work around this, the 9 look-direction animations, 5 eyebrow animations, 6 eyelid animations (3 per eye), and 5 mouth animations are combined via a script into unique animations representing every possible state. This results in 2,025 generated animations. Since each additional animation dramatically increases this count, no further animations are planned until the animation system receives an overhaul.
Offer players the ability to define custom animation triggers. The goal is to allow playful mappings, such as triggering a horn wiggle animation when the player blinks.
