Picker Namespace
A namespace is a naming prefix for the current picker, changing of namespace enables you to use the picker on different rigs as long as they have similar naming conversions.
To set the picker namespace: You simply edit the text shown in the top namespace area. The
Ctrl+Alt+Shift+Shotkey in animator mode will just activate the text area.To Grab the namespace from Maya selection: Simply click on the
button.
Picker Sub-Namespace
Most types of picker item (Select-button, command-button, attr-Button, slider) may contain a sub-namespace if it is set durning the designing process.
A sub-namespace is an addition to the picker namespace.
Say your picker namespace is set to myCharacter, and there is a select button has the sub-namespace bodyRig:chestRig, the select-button contains a member called chest_ctl, then the final Maya control will turn out to be this:
myCharacter:bodyRig:chestRig:chest_ctl;
This means when you click this select-button in animator mode, the tool will try to select myCharacter:bodyRig:chestRig:chest_ctl in Maya scene.
