Digit Manager

The Digit Manager provides controls for posing the digits on a palm procedurally. The Digit Manager rollout appears on the Motion panel for a selected palm with one or more digits, although it’s most useful with palms that have multiple digits.

• Select a palm bone with one or more digits. > Motion panel > Palm Animation rollout

Tip: You are not limited to using CAT’s digit-manipulation controls for posing hands. You can also select individual digit bones in the viewport and transform them as normal.

Note: As elsewhere in this help, any reference to a palm in this topic applies equally to an ankle.

Procedure

To access the Digit Manager rollout:

1. Select a palm bone on a rig.

   By default, a newly created palm has no digits; to use the Digit Manager, you need to add some.

2. On the Modify panel Palm/Ankle Setup rollout, set Num Digits to a value greater than 0. For example, with a human character, youd set it to 5.
3. Go to the Motion panel and expand the Digit Manager rollout, if necessary.

Interface

The Digit Manager rollout includes two groups: Preset Poses and Digit Modifiers.

Preset Poses group

The Preset Poses list holds digit poses. A digit pose comprises the rotations for all digit bones on the palm or ankle. With the controls in this group you can save pose presets and then load them onto any other palm.

If the palm to which you apply a pose has fewer digits than those of the pose preset, the extra digits are ignored. If the palm has more digits, the extra digits receive no rotation data.

You can weight a pose preset, blending from one pose to another or mixing poses to create a new preset.

[pose list]

Lists saved preset poses.

To apply a preset to the selected palm without blending, double-click its name in the list.

Weight

The amount that the highlighted preset has on the digits.

To blend a preset, select the palm, click a preset pose in the list once to highlight it, and then adjust the Weight value upward.

Note: The Weight value is relative, so that if you apply the same value several times, as long as the highlighted preset pose has been applied only partially, the blend amount increases.

Store Preset

Saves the current digit rotations as a new pose preset.

Tip: By default, digit poses are stored in separate files in \[system folder]\plugcfg\CAT\HandPosePresets\.

You can use the Save As dialog to save poses in a different location, but they won’t then appear in the Preset Poses list.

Remove Preset

Deletes a pose preset from the Preset Poses list.

Warning: Removing a preset deletes the file containing the preset permanently without prompting you.

Digit Modifiers group

The Digit Modifiers group provides tools to enable you to manipulate the digits, either singly or as a group. You can transform selected digits parametrically with the Spread, Bend, Roll, and Curl controls.

Note: All modifications are relative to the existing rotations.

[digit list]

Lists all digits on the selected palm. Before applying controls from this group, highlight the digits that the controls should affect.

Tip: You can highlight multiple contiguous list entries by dragging in the list.

Spread

Rotates highlighted digits away/towards each other from the base of the digit.

Bend

Rotates highlighted digits up and down from the base of the digits.

Roll

Rotates highlighted digits around their length.

Curl

Rotates bones of highlighted digit7s up and down.
