The primary axis of the input skeleton that points to the next child joint. Any rig components added with this node uses this axis as their primary axis for new joints or controls, if applicable.

The secondary axis of the input skeleton, which is the rotation axis that the animator most often uses. Any rig components added with this node uses this axis as their seconday axis for new joints or controls, if applicable.

When turned on, enforces auto reorientation of the joints. This is automatically turned on when using rig templates.

When Reorient is turned on, these are the guide joints that are excluded from the automatic reorientation.

The name of the detail orientation attribute that is created on the output skeleton if the reorientation is used.

The pattern to identify the joints on the left side of the input skeleton. This pattern is also used to name the new controls and joints on the left side of the character.

The pattern to identify the joints on the right side of the input skeleton. This pattern is also used to name the new controls and joints on the right side of the character.

When turned on, creates an FK control for every joint on the input skeleton. This option is helpful if you want to start building a new rig with this node. Turn this off if you already have an existing rig that you only want to update with this node.

When turned on, removes the tags on the input skeleton before performing any processing. This parameter is available when Input Skeleton to FK is turned on.

When turned off, doesn’t add the new joints created by this node to Base.skel. This makes the skeleton processing more efficient when working with an existing skeleton that has a heavy joint count.

The joints to exclude when building the FK controls. This parameter accepts tags.

When turned on, mirrors the guide joint transformations from left to right.

The guide joints to exclude when mirroring transformations from left to right. This parameter accepts tags.

When turned on, automatically determines the joint size based on the size of the character.

When Automatic Joint Size is turned off, this is the size of the guide joints.

The position of the test rig in the viewport.

When turned on, creates proxy weights for the character and provides a better preview of the rig functionality even if you don’t have capture weights on your input character.

The guide joint that the segment is parented to. New segments joints are parented to this joint.

The guide joints to exclude from the segment. For example, if you want to add a hand component but you only need three fingers, the extra two fingers can be marked to be excluded. See the Autorig Builder page for an example of how to do this.

The number of guide joints for the segment. This is used for components that can have a varying number of guide joints, for example, a spline or FK joint chain. This parameter is populated when the number of elements is set using the number of elements icon in the guide’s menu.

The joint mappings between the component’s reference skeleton and the working skeleton. The component’s reference skeleton is stored internally and is used to represent the joints needed by the component. It is also used to transfer tags and properties to the working skeleton.

The joint from the component’s reference skeleton to map from.

The joint on the working skeleton to map to.

The shapes to apply the manual edits to. If a control is not specified in this parameter, the manual shape edits are not applied to the control.

Removes any manual changes to the shape, color, and transformation of control shapes made in the tweak control shapes mode (see “Tweak control shapes” in the Autorig Builder how-to).

When turned on, creates selection sets for the different LOD controls. For example, if you add arm and leg segments to the character, the FK and IK controls are added to an LOD_1 selection set, and the twist controls are added to an LOD_3 selection set. The following selection set hierarchy is created:

LOD_1/
    <Arm FK and IK controls>
    <Leg FK and IK controls>
LOD_2/
LOD_3/
    <Arm twist controls>
    <Leg twist controls>

When turned on, creates selection sets for the different segments. The top-level selection set is named bodyparts, and the sets for the segments are nested underneath. For example, if you add a leg segment to the character, the following selection set hierarchy is created:

bodyparts/
    L_leg/
    R_leg/

When Add Segment Sets is turned on, these are the segments to create selection sets for.

When Add Segment Sets is turned on, these are the colors to use for the selection sets.

When turned on, adds the controls into LOD subsets within the segment selection set. For example, if you add a leg segment to the character, the following selection set hierarchy is created:

bodyparts/
    L_leg/
        LOD_1/
        LOD_2/
        LOD_3/
    R_leg/
        LOD_1/
        LOD_2/
        LOD_3/
