Chapter 22: Animating with Constraints and Simple Controllers

Note
Because controllers are automatically assigned to animation tracks, they cannot be removed; they can only be
changed to a different controller. There is no function to delete controllers. n

Assigning controllers with the Animation menu
The easiest way to assign a controller to an object is with the Animation menu. Located under the
Animation menu are four controller submenus consisting of Transform, Position, Rotation, and Scale.

Note
Although constraints are contained within a separate menu, they control the animating of keys just like controllers. n
When a controller is assigned to an object using the Animation menu, the existing controller is not
removed, but the new controller is added as part of a list along with the other controllers. You can see all
these controllers in the Motion panel.
For example, Figure 22.7 shows the Motion panel for a sphere object that has the default Position XYZ con-
troller assigned to the Position track. If you choose Animation ➪ Position Controllers ➪ Noise, then the
Position List controller is added to the Position track, of which Position XYZ and Noise are two available
controllers. This lets you animate multiple motions such as the shimmy of a car with a bad carburetor as it
moves down the road.
