Edit pole vector constraints

A target object’s weight specifies how much the position of the constrained pole vector can be influenced by a target object. By default, the weights are set to 1, but you can change the weights so that some target objects can have more (or less) influence than others by editing the targetObject Wn attributes in the Channel Box or the Attribute Editor.

The constrained pole vector’s end position is driven by the target point, but you can offset the end position from the target point. To do so, edit the constraint Offset and Offset Polarity attributes with the Attribute Editor.
Note: The constraint Offset and Offset Polarity attributes are not displayed by default as channels in the Channel Box. If you want to control them from the Channel Box, add them with the Channel Control editor (select Window > General Editors > Channel Control).

To edit pole vector constraint attributes with the Attribute Editor

  1. Select the pole vector constraint node.
  2. Open the Attribute Editor.
  3. The following sections make available attributes: Transform Attributes, Pole Vector Constraint Attributes, Pivots, Limit Information, Display, Node Behavior, and Extra Attributes.
  4. Do one of the following:
    • Click Select to select the node you are now editing as the currently selected object in your scene.
    • Click Load Attributes to load the attribute values of the currently selected node.
    • Click Copy Tab to open a separate window containing the attributes for the selected node.

To edit pole vector constraint channels with the Channel Box

  1. In the scene, select the constrained pole vector’s IK rotate plane handle.
  2. Set the channels.
  3. Click the channel you want to edit.
  4. In your scene, middle-click and move the mouse to the left or right. By moving the mouse, you interactively change the value of the selected channel. As you move the mouse, note that pressing the Ctrl key gives you finer control, and pressing Shift gives you coarser control.
