single parameter controllers such as a Bezier Floa t
controller for Height or TCB for Rotation. These
controllers use a Key Info dialog that contains
settings for one of more selec ted keys.
To view k ey i nformation in the Cur ve Editor:
• Right-clickakeytodisplaytheKeyInfodialog.
If more than one key is highlighted, Key Info
displays common information for all of the
selected keys. Settings that contain values
indicate values common to all of the selected
keys. Settings that are blank indicate values that
change from key to key.
Viewing key information in the Motion panel
always displays the settings for a single transform
key.

2. On the Motion panel, click Parameters, if it’s

If the transform controller uses keys, Key Info
rollouts appear below the Parameters rollout.

That Do Not Display Proper ties
Some controller types do not display any
properties in Track View or the Motion panel. You
change the animation values of these controllers
using the A uto Key button in the viewports and
using the tools i n the Curve E ditor Keys and
Curves menus, and in the track bar.
As signi ng Contr oller s
Every parameter has a default controller ty p e
that gets assigned the moment t he parameter is
animated.Youcanchoosefrommultiplecontroller
types for any par ameter and change controllers
after the parameter is animated.
Assigning Controllers in Track View
You can assign controllers to any animatable
parameter in the Curve Editor by selecting
controller items and then choosing Assign
Controller on the Controller menu.
You can also assign controllers to any animatable
parameter in the Track View — Curve Editor by
selecting the parameter in the Hierarchy List then
rig ht-clicking and choose Assign Controller from
the quad menu.
You can also assign the same cont roller type to
a selection of multiple parameters as long as all
the selected parameters can use the same type
of controller. For example, you could select the
Length, Width, and Height parameters for multiple
Box objects and assign the same controller type to
all of them. This is because they all use controllers
that work on floating point d ata.
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
