When turned on, activates IK for the limb.

A larger value dampens the effect of the IK solve, smoothing its snapping effects at the cost of accuracy.

A larger value allows more stretch for the IK chain when the target is beyond the length of the chain.

Sets the accuracy of the solve. A higher value is faster but less accurate.

When turned on, uses the pole vector to twist the IK chain.

When turned on, sets the pole vector control to world orientation.

When turned on, sets the root control to world orientation.

When turned on, sets the tip control to world orientation.

When turned on, uses the goal rotation for the target orientation. When turned off, uses the solver’s position for the target orientation.

When turned on, resists straightening of the IK chain.

The amount to offset the pole vector in the direction of the middle joint (between the root and tip). The IK chain must be slightly bent for this to work.

When turned on, adds IK/FK blending to the limb setup.

Segments are tags that separate each IK chain. For example, *Leg loops over tags L_Leg and R_Leg. Tags can be set up on skeleton joints using an Attribute Adjust Array SOP. See preparing skeletons for rigging for more information.

If Segments is empty, the IK logic is run once.

The Segments name is added to the name of the TransformObject nodes created by this component.

The nodes to drive. You can specify the individual joints, for example, L_Hip, L_Knee, L_Ankle, or a tag that exists on the TransformObject nodes, for example, %tag(ik) & %tag(L_Leg).

It is good practice to also specify the bind tags that are set up by default on the FK transform component’s Tags parameter. The FK transform component is normally the first component that is used to start building a rig. Including the bind tag helps to ensure that you don’t include other controls that might have inherited, for example, the L_Leg tag. So for this component, you can set Driven to %tag(bind) & %tag(ik).

The name of the root control. If Segments is used, the Segments name is added to the name of the control.

The name of the pole vector control. If Segments is used, the Segments name is added to the name of the control.

The name of the tip control. If Segments is used, the Segments name is added to the name of the control.

The tags to use for the twist setup.

The position of the pin offset control. This control drives the up vector of the pinned root of the twist chain. See the twist rig component’s Pinoffset parameter for more information.

When turned on, displays the twist controls.

The tags of the joints to use for the clavicle setup. This usually includes the clavicle and shoulder joints.

When turned on, displays the limits of the auto clavicle setup.

The cone constraint angle for the clavicle.

The offset rotation of the cone constraint for the clavicle.

The amount of rotation blended in from the cone constraint.

The parent of the auto clavicle driver. This parent cannot be a descendant of the clavicle. The default parent is the IK tip, which produces the best results for an auto clavicle setup.

The parent of the root control(s). When empty, the root control has the same parent as the root node of the IK chain. To unparent the root control, set this parameter to an underscore (“_”).

The parent of the tip control(s). When empty, the tip is not parented.

The parent of the pole vector(s). When empty, the pole vector is parented to the tip.

The tags to add to the roots created by this component.

The tags to add to the pole vectors created by this component.

The tags to add to the targets created by this component.

The shape of the controls. It can be set to any of the built-in APEX control shapes.

The scale of the control shapes.

The color of the control shapes.
