The built-in GestureLeft and GestureRight parameters identify the user's hand gesture, while GestureLeftWeight and GestureRightWeight expose analog trigger pressure. On humanoid avatars, the Gesture playable layer is commonly used for hand poses, while facial expressions are often driven from the FX layer with blendshapes, material properties, or other non-humanoid animations.
