Nodes

HumanIK Relative Pin Refresh This is a tuning node for the “Relative Pin” constraint.

Outputs
		Out		event	This event is triggered when the node finishes its evaluation.
Inputs
float		Constraint Id			The constraint Id for retrieving and tuning the constraint.
unit		Unit			The character unit.
event		In			This event triggers the evaluation of this node.

It refreshes the relative transform between the external unit and the pinned effector. At refresh time, the Constraints compute and store a relative transform between the effector (in its FK state) and the external unit; the Constraint will preserve this relative transform during the next frames.

Available in Unit Flow Editor, Level Flow Editor, and External Flow Editor.

Inputs
float		Constraint Id			The constraint Id for retrieving and tuning the constraint.
vector3		Position			The new position to aim at.
unit		Unit			The source character unit.
event		In			This event triggers the evaluation of this node.

Use this node to designate a new target position to aim at.

HumanIK Set Aim Target Unit This node operates on an Aim constraint; it can only be called when an Aim constraint has been previously added to the character.

Outputs
		Out		event	This event is triggered when the node finishes its evaluation.
Inputs
float		Constraint Id			The constraint Id for retrieving and tuning the constraint.
string		Target Effector			The target effector to aim at. Accepted values: Hips Left Ankle Right Ankle Left Wrist Right Wrist Left Knee Right Knee Left Elbow Right Elbow Chest Origin Chest End Left Foot Right Foot Left Shoulder Right Shoulder Head Left Hip Right Hip Left Hand Right Hand
unit		Target Unit			The target character unit to aim at.
unit		Unit			The source character unit.
event		In			This event triggers the evaluation of this node.

Use this node to designate a new target character to aim at (or none at all, to disable the aiming behavior).

HumanIK Set Blend Alpha Lets you set the current strength of any constraint in the current IK constraints stack.

Outputs
		Out		event	This event is triggered when the node finishes its evaluation.
Inputs
float		Blend Alpha			The alpha value to set for the constraint (between 0.0 and 1.0).
float		Constraint Id			The Id of the constraint.
unit		Unit			The character unit.
event		In			This event triggers the evaluation of this node.

A blend alpha value of 0.0 totally disables a constraint. A blend alpha value of 1.0 fully enables a constraint. Any value in between is allowed.

The HumanIK plug-in handles the transition between values, so if a constraint was fully active (blend alpha = 1.0) and you disable it (setting its blend alpha to 0.0), the alpha value smoothly decreases and there is no pop/discontinuity. Refer to the HumanIK Set Blend Time node to learn how to change the blending speed.

HumanIK Set Blend Time Lets you set the blend in/out time of any constraint in the current IK constraints stack.

Outputs
		Out		event	This event is triggered when the node finishes its evaluation.
Inputs
float		Blend Time			The blend time (in seconds).
float		Constraint Id			The Id of the constraint.
unit		Unit			The character unit.
event		In			This event triggers the evaluation of this node.

A blend time value of 0.0 makes the constraint pop in/pop out. Any higher value indicates the number of seconds it takes for a constraint to blend from totally disabled (alpha = 0) to totally enabled (alpha = 1).
