Set Driven Key window

(Animation menu set) Key > Set Driven Key > Set

With the Set Driven Key window, you can link objects so that one object’s attributes can drive or dictate the attributes of another object. See Driven keys and Use driven keys to link attributes.

To...	Do this
Load the driver linked to a selected, loaded driven object.	Select Load > Current Driver. The driver of the current driven object appears in the Driver list.
Load only shape nodes for a selected object.	Turn on Options > Load Shapes before clicking Load Driver or Load Driven.
Add an object to the existing Driver or Driven list.	Turn off Options > Clear On Load before clicking Load Driver or Load Driven.
List the keyable or nonkeyable attributes for a selected object.	To list keyable attributes, turn on Options > Show Non-Keyable Attributes. Turn this option off to list nonkeyable attributes. Tip: Use the Channel Control Editor (Window > General Editors > Channel Control) to control whether an attribute is keyable or nonkeyable.

Driver list

The name of a selected driver object displays in the left column, and the object’s keyable attributes display in the right column. Select one of the attributes in the right column as the driver attribute.

Load menu

Selected as Driver: Sets the current object as the driver object. Selected as Driver performs the same function as clicking the Load Driver button in the Set Driven Key window.

Options menu

Clear on Load: When on, loading a driver or driven object deletes the Driver or Driven list’s current contents. When off, loading a driver or driven object adds the current object to the Driver or Driven list.
Load Shapes: When on, only the shape node attributes of the object being loaded appear in the right-hand columns of the Driver or Driven lists. When off, only the transform node attributes of the object being loaded appear in the Driver or Driven lists.
Auto Select: When on, selecting an object in the Set Driven Keys window automatically selects it in the scene view. When off, selecting an object in the Set Driven Keys window does not select it in the scene view.
Show Non-Keyable Attributes: When on, only the keyable attributes of the object being loaded appear in the right-hand columns of the Driver or Driven lists. When off, all attributes—keyable and non-keyable—of the object being loaded appear in the right-hand columns of the Driver or Driven lists. See Edit the keyability of an object.

Note: In earlier versions of Maya, Show Non-Keyable Attributes was called List Keyable Driven Attributes. The name has been changed to reflect that this setting filters to show only attributes that you cannot set key frames on.

Key menu

Set: Links the selected Driver and Driven object’s attributes at their current values. Performs the same function as clicking the Load button in the Set Driven Key window.
Go to Previous and Go to Next: Cycle through the keys for the driven attributes of the current object and view the object's state at each of these keys. See Use driven keys to link attributes for information on viewing driven objects.

Select menu

Driven Items: Selects the current object in the Driven list in the scene view. For example, if cone 1 is selected in the Driven list, Select menu > Driven Items selects cone1 in the scene view.
