Generated Rig Features

Each limb will have a gear widget at its base. This is the utility bone that contains all the sub-rig properties. The rig features will be displayed anyway when the affected bone is selected but if you are looking in the Graph editor for those properties’ animated values, this is most likely the bone to look at.

Depending on the user defined meta-rig options, multiple deform bone segments will be created. Each bone can be controlled by tweak controls placed at the respective bone’s head/tail. Tweaks are subordinate to the general IK or FK limb position but can be moved apart, twisted and scaled freely, even reaching virtually impossible limb shapes.

Rigify’s limbs have the following controls in the Sidebar panel:

FK Limb Follow Slider

When set to 1 the FK limb will not rotate with the torso and will retain is rotation relative to the root bone instead.

IK-FK Slider

Controls whether the limb follows IK or FK controls, blending between full IK at 0 and full FK at 1.

IK<->FK Snapping Buttons

Each snap direction has buttons to update just the current pose, bake the whole animation in the current Action, or Clear keyframes instead of snapping. The buttons dealing with keyframes use options from an additional panel to control the range of frames to bake.

IK Stretch Slider

Blends between the limb stretching freely at 1, or having its maximum length constrained at 0.

Toggle Pole Switch

When set to 0 the IK limb will use the rotational pole vector (the arrow at the base of the limb). Rotating/translating/scaling the arrow will control the IK limb base. When set to 1 the classic pole vector will be displayed and used to orient the IK limb. The arrow will continue to handle the scale and the location of the IK limb base.

Similar to IK-FK Snapping, the row includes buttons to convert the current pose between types, or bake the whole action.

IK Parent Switch

Switches the effective parent of the main IK control, with different integer values corresponding to choices from a list.

The row includes buttons that allow converting the current pose via choosing from a menu, or baking the whole action.

Switches the effective parent of the classic IK Pole control.

Neck Follow Slider

This slider controls the rotations isolation for the neck bones. When set to 0 the neck will stay oriented as the Torso (the big box control). When set to 1 the neck will be oriented as the Chest (the big circle in the shoulder area).

Head Follow Slider

This slider controls the rotations isolation for the head. When set to 0 the head will stay oriented as the Torso (the big box control). When set to 1 the head will be oriented as the neck.

Mouth Lock Slider

This slider controls the mouth opening. When set to 0 moving/rotating the jaw bone will result in mouth opening, when set to 1 the lips will stay sealed while the jaw is moving.

Eyes Following Slider

This slider controls the eyelid automation. When set to 1 the eyelids and the lower eyebrow will follow the eye movement giving a realistic effect to the character, when set to 0 no automation will happen.
