Dynamic Gesture Asset

Defines the behavior and integration of a custom hand gesture for use with the Dynamic Gesture System. A DynamicGestureAsset encapsulates configuration for gesture playback, animation behavior, tracking control, and gesture override targets.

Once created, the asset can be installed and assigned to a DynamicGesture component to enable gesture functionality.

Properties

GestureName

The display name of the gesture. Shown in the Expression Menu.

GestureIcon

The icon associated with this gesture, displayed in the Expression Menu.

MotionType

Defines the playback behavior of the assigned animation.

Value	Description
BlendTree	Blends multiple animation clips based on GestureWeight.
MotionTime	Plays a single animation at a frame corresponding to GestureWeight.
Speed	Adjusts the playback speed proportionally to GestureWeight.

OverrideGestures

Specifies which default VRChat gestures this asset will override. The listed gesture types are replaced with the configured dynamic gesture behavior at runtime.

Motion Types

BlendTree

Plays multiple clips blended by the GestureWeight parameter.

• GestureWeight range: 0.0f (open hand) ↔ 1.0f (closed fist)
• Use when smooth transitions between multiple poses are required.

INFO

GestureWeight values:

0.0 → Open hand

1.0 → Closed fist

MotionTime

Plays a single animation at a normalized time based on GestureWeight.

• GestureWeight maps directly to the animation’s normalized time (0 → 1).
• Use for progressive gesture animations directly controlled by hand openness or trigger pressure.

INFO

Example: GestureWeight = 0.5 → The animation plays from the middle frame.

Speed

Plays a single animation at a speed scaled by GestureWeight.

INFO

GestureWeight = 1.0f → 100% playback speed

GestureWeight < 1.0f → slowed playback

Advanced Properties

TrackingType

Specifies how hand tracking is handled when the gesture state is active. A VRCAnimatorTrackingControl is automatically added to the state.

Value	Description
Tracking	Keeps VRChat finger tracking active.
Animation	Disables tracking, allowing animation to take full control.

Recommendation

Use Animation if the gesture animation should override finger tracking. Otherwise, tracking input may interfere with the animation.

IntroAnimation

Optional. Defines an animation to play once when entering the gesture state from a standard VRChat gesture.

• Can be assigned per incoming VRChat gesture.
• Play before the gesture animation begins.

Use case: Adding transition animations for a more natural gesture change.
