The non-modal CATMotion Editor dialog holds all of the controls for CATMotion. You can open a separate window for each CATRig in your scene and edit settings at any time without having to reselect the rig. This is convenient when working with multiple rigs.
A separate editor window for each rig in the scene
To open a CATMotion Editor dialog, click 
CATMotion Editor on the Layer Manager rollout. This button replaces the Display Layer Transform Gizmo button when a CATMotion
layer is highlighted in the layers list.
The CATMotion Editor button is available only when a CATMotion layer is highlighted in the layer stack.
The editor dialog comprises two panels: On the left is the CATRig hierarchy, which mirrors the rig structure and includes the CATMotion controllers, and on the right is a control panel for the item currently highlighted in the hierarchy.
The first three items in the hierarchy list are found in every CATRig: CATMotion Presets, Globals, and LimbPhases. The remaining hierarchy is organized by HubGroup.
CATMotion works by first breaking up the rig into its elements (the CATRig hierarchy) and then assigning each element a series of controllers, each of which handles one aspect of the motion of that element.
Each aspect of a particular motion (for example, the way the pelvis movees) has its own spline control. The combination of so many controllers allows for a wide range of possibilities in creating distinctive character animation.
A CATMotion preset comprises the saved settings for all the controllers in the CATHierarchy in the active CATMotion layer.
