Enabling the Posed Deformer Preference

The first thing you should do when rigging your character turnaround is to make sure to select the Automatically Create New Deformer Structure for Each Pose/Drawing preference. This preference is on the Deformation tab of the Preferences dialog box; by default this option is selected.

When rigging with this preference enabled, notice that the structure of the deformation inside the Deformation group is slightly different than when executing a basic rig with the preference disabled.

Each pose you rig within the same element is part of a separate subgroup all of which are gathered together by a Deformation-Composite module; each subgroup is called by its drawing number or name. These subgroups cannot be renamed once the rig is complete, as the name of the group and drawing is the link between them. If you kept the default drawing numbering of 1, 2, 3, and so on, your groups will be called 1, 2, 3, and so on. For this reason, you might want to rename your drawing before you start rigging so the names correspond to the poses. For example: front, side, quarter, etc.
