keyingGroup node

Go to: Attributes.

The keyingGroup node is a special type of set. It is used to gather together animatable attributes. These attributes can then be animated and edited in unison.

KeyingGroup sets may only contain animatable attributes and other keying groups.

Objects within keying groups can be designated activator objects. When a key is set on an activator object, it triggers keyframing of the other objects within the keyingGroup.

Maya also maintains a global keyingGroup filter preference which can be used to globally enable/disable all keyingGroups or to specify particular keyingGroups to be active. The category attribute may be used to designate a filter-able keyingGroup type.
