Edit cluster deformers

To edit cluster channels with the Channel Box

Select a cluster deformer node (default name: clustern).
One quick way to select the cluster deformer node is to select the object being deformed, and then select the cluster deformer node in its history from the Channel Box (under INPUTS). Another way is to select the cluster deformer handle (the C icon).

Note that you can control which attributes are listed as keyable attributes (channels) in the Channel Box with the Channel Control editor (select Window > General Editors > Channel Control).
In the Channel Box, the following channels are listed by default:
Click the name of the channel you want to edit.
In your scene, -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 key gives you finer control, and pressing the key gives you less control.

To edit cluster deformer attributes with the Attribute Editor

Select the cluster deformer node (default name: cluster).
Open the Attribute Editor by selecting Window > Attribute Editor or by using the default shortcut +a.
Edit the attributes.
See cluster.

To prune deformer set membership

Select deformable objects whose currently unaffected points you want to prune from the deformation.
Select Edit Deformers > Prune Membership > Cluster.
Maya removes the deformable object’s points currently unaffected points from the cluster deformer set.

Note
Prune Membership only removes points from the deformation if they are currently not affected by the deformer. Therefore, if you try to prune the membership of an object whose points are all controlled by the deformer, you will receive the error message “No components could be pruned.”

To query cluster weights

Select the points whose cluster weights you want to edit.
Select Window > General Editors > Component Editor.
The Component Editor appears.

The Component Editor displays the component data for currently selected components in the workspace.

By default, the Component Editor updates dynamically as you select components in the workspace. Also, as you select components in the Component Editor, the workspace updates dynamically.
Click on the Weighted Deformers tab. The Weighted Deformers section lists the weights assigned to CVs, vertices, or lattice points by cluster deformers (default names: clustern).

To modify a point’s cluster weight

In the Component Editor’s spreadsheet, click the component data box you want to edit.
Only the component whose box you’ve selected is now selected in the workspace.
Enter a new value.

To modify several cluster weights at once

In the workspace, select the points whose weights you want to edit.
In the Component Editor’s spreadsheet, drag through the component data boxes you want to edit.
Enter the value you want all the boxes to have.

To modify an entire row or column (Linux and Mac OS X only)

In the workspace, select the points whose weights you want to edit.
In the Component Editor’s spreadsheet, click one of the boxes in the row or column.
Click the row or column heading.
Now all the boxes for the row or column are selected.
Enter a value for all the boxes in the row or column.

To modify an entire row or column (Windows only)

In the workspace, select the points whose weights you want to edit.
To change all the entries of a row or column, in the Component Editor’s spreadsheet, select the row or column heading.
-click any of the boxes in that row or column.
Enter a new value to update the entire row or column.
For more information see Component Editor.

To delete a cluster deformer

Select the cluster deformer node.
Select Edit > Delete or use the default shortcut (Linux and Windows) or (Mac OS X) key.
The deformer nodes are all deleted. However, the object still has the tweak node as an input node, so any tweaks you might have made are preserved.
