If a parameter has already been animated, then assigning a new controller has
one of the following effects:
■ The existing animation values are recalculated to produce a similar
animation with the new controller. For example, replacing TCB Position
with Bezier Position closely preserves the animation.
■ The existing animation values are discarded. For example, replacing Smooth
Rotation with Noise Rotation discards the Smooth Rotation animation
values.
Assigning Controllers in the Motion Panel
You can assign controllers on the Motion panel by selecting an object and
then, on the Assign Controller rollout, choosing a controller and clicking the
Assign Controller button. You can change the controllers of only one selected
object.
Assigning Controllers Using the Animation Menu
You can assign controllers using the Animation menu. All the controllers and
constraints are available by going to the menu bar and choosing Animation,
and then selecting the type of Controller you want and picking the controller
from the submenu that displays.
When you assign a controller in this method, a list controller is automatically
assigned, and the controller you have selected appears as the first entry in the
list. This automatic list controller assignment does not occur if you assign
controllers using the Motion panel or Track View. Weighted list controllers
allow you to blend between various tracks by animating the weights.
TIP You can use the Animation menu to assign the same type of controller or
constraint to several different objects at once. Just select the objects and then
choose the controller or constraint from the Animation menu.
NOTE If an assigned constraint requires designating an additional subject, such
as a Path constraint, a rubber-band line extends from the first selected object to
the mouse cursor after choosing the constraint. To complete the assignment,
position the cursor over a qualifying target object and click.
