The List controller combines multiple controllers
into a single effect. It is a compound controller
with tools for managing the order in which its
internal controllers are calculated. Controllers are
evaluated in top-to-bottom order . In addition, you
can specify a Weight setting for each cont roller in
the list to determine its relative influence.
When you assign a List controller to a parameter,
the current controller is moved one level below the
List cont roller; it becomes the first cont roller in
the list. A second parameter, named Available, is
added below the List controller. This is an empty
placeholder for the next controller you add to the
list.
By default, each listed controller’s Weight setting
is set to 100.0. This setting can be changed to
increase or decrease the effect the controller has
on an object.
When you assign a controller using the Animation
menu, a list cont roller is automatically assigned as
a default, with the chosen controller placed first in
the list. This behavior differs from when you assign
a controller in the Motion Panel or Track View,
where only the specified controller is assigned.
You can animate List controller weig hts to achieve
the equivalent of a non-linear animation system.
Each list controller track can hold different val ues
from frame to frame that you can turn on or off, or
blend between by animating the weig hts.
Procedure
Ex ample: To use the L ist controll er to combine two
controllers:
1.
Create a box, and then turn on Auto Key.
2. Create a simple animation containing three
position keys.
3. On the Motion panel > Parameters > Assign
Controller rollout, click the position track.
4. Highlight the Position transform and click
Assign Cont roller.
5. Choose the Position List in the Assign Position
Cont roller dialog. Click OK.
6. Click the plus sign in the Position t rack to
expand the track.
A Position XYZ track and a tr ack labeled
Available are now visible.
