After you create the squash deformer, its handle is displayed in your scene and its nodes are listed in the Channel Box. The nodes include the squash handle node (default name: squashnHandle), the squash handle shape node (squashnHandleShape), and the squash deformer node (default name: squashn).

You can edit the effects of the squash deformer by editing the squash handle node and the squash deformer node. You can move (translate), rotate, and scale the squash handle to edit the effects of the deformation. You can also edit the squash deformer node’s keyable attributes (channels), which are displayed in the Channel Box.
