tweak

Stores transformation information for the vertices of the current skin. Tweak also ensures the proper transformation of skin vertices when you manipulate a character’s skeleton. When you delete the tweak node, all the transformation information for the vertices that are affected by the influence joints and object is erased. Deleting the tweak node is an easy way of removing deformations from a skin.

Component Tags and Tweak nodes

No tweak nodes are added to deformations when you use Component Tags. However, sometimes you may need to make the componentTag shape behave the same as the deprecated GroupID shape by adding a tweak node.

If you want to continue using tweak nodes, there are a few options:

• If you want to have tweak nodes created whenever you add deformers to your scene, activate Create Tweak in the Animation Settings Preferences (Rigging area)
• to add a tweak node to your deformation after creation, select the deformer in the Attribute Editor and choosing Add Tweak from the Deform menu options
• Use the -createTweakNode element in the deformableShapes command:

  deformableShape

  -createTweakNode TagShape;
