Scales down the length of actors' strides when walking at very slow speeds in a CrowdFX simulation. This generally gives better-looking
results than simply playing the animation very slowly. This compound works in conjunction with the parameters set in Initialize Locomotion Data.
This compound can be used only in the Simulation region of the Point_Cloud object after Set Locomotion, but before any other constraints involving the legs.
For more information, see Controlling the Stride.

Set this value to the height of the foot effector in the rig. This value is used to clamp the result of . The amount of foot lifting will never be scaled to a value lower than this.
|
|
You don't want to scale any rig elements below the height of the ankle when the foot is on the ground.

|
The factor used to scale the amount of foot lifting at very slow speeds. This avoids a "high-stepping" walk animation when
scaling the length of stride. Use values between 0 and 1 to scale down.

|
A reference to the left/right leg root bone in the actor's Rig_Proxy.
|
|
|
A name to prefix to Root to fully resolve the name.
|
|
|
A reference to the left/right knee (shin) bone in the actor's Rig_Proxy. This should be a child of Root.
|
|
|
A name to prefix to Knee to fully resolve the name.
|
|
|
A reference to the left/right leg effector in the actor's Rig_Proxy. This should be a child of Knee. In addition, the corresponding
feet bones and effector should be descendants of this object.
|
|
|
A name to prefix to Effector to fully resolve the name.
|
|
|
The local vector of the leg root bone that points at the knee.
|
|
|
The local vector of the knee bone that points at the effector.

TipIf the simulation includes multiple actor sources, you can plug multiple instances of this node into a Select Case node with
its Condition port driven by Get Actor ID. This allows you to use different values for different actor types.
