A pose (FBPose) is a snapshot or copy of a character's position. It can be the snapshot position of an entire object (FBObjectPose), a character's whole body (FBCharacterPose), or only selected body parts. For example, you can create poses of hand and finger positions, and save these poses as templates. You can apply these poses to other characters so that they get the same hand and finger positions. You can apply poses on any character that has a control rig.
For more information on how to create and apply a pose, see the FBPose - Poses help topic.
