controller in the list will blend to and from that
pose (controller in list). If the last weig ht is 100.0,
then adjusting the weig hts of the previous poses in
the l ist won’t have any effect because the last pose
has full effect. This is a stack-based approach that
is best used for nonlinear animation (NLA) e ffects.
You can paste motion clips or even single-frame
poses onto new layers and use the weights to blend
the poses together.
Editable Name Field—Select one of the controllers
in the list window of the Controller list, and then
enter a descriptive name in this field. This field lets
yo u rename the controller so it’s easier to identify.

Con troller
This controller is no longer available. You can,
however, st ill edit objects that were assig ned this
contr o ller previously.
The Local Euler Rotation controller is similar to
the Euler XYZ Rotation controller (page 2–318),but
the angles are with respect to the rotated object’s
local coordinate system. With the standard Euler
Rotation controller , angles are with respect to
parent coordinates. Parameters for this controller
are displayed in the Motion panel.
The Local Euler XY Z Rotation controller has t hree
rotation tracks to control rotation on the X, Y,
and Z axes. Setting an X axis rotation key will
not create keys in the Y and Z tracks on the same
frame; each track can be keyed independently.

The Loc a l Euler parameters are displayed in the
Motion panel.
Euler Parameters rollout
This rollout is displayed when you select Rotation
in the PRS Parameters rollout (page 2–357).
Axis Order—Sets the order that rotations are
calculated in the list. The default is X,Y,Z order,
wheretheXaxisisrotatedfirst.
X—Displays controller properties for X axis
rotation angle.
Y—Displays controller properties for Y axis
rotation angle.
Z—Displays controller properties for Z axis
rotation angle.
Each axis uses its own independent controller
using the float data type. For example, the X and
Y rotation axes could use Bezier Float controllers,
while the Z Rotation axis uses a Noise Float
controller.
Look At Contr oll er
Create or select an object that contains a Target
component, such as a target spotlig ht or camera. >
Motion panel > Look At Parameters rollout
The Look At controller is automatically assigned
asatransformanimationcontrolleruponcreation
of objects that contain targets, incl uding Target
Camera, targeted lights (including I ES Sun/Sky)
and t he Tape helper. It cannot be assig ned by
the user. To assign the equivalent of a Look At
controller to an object, use a LookAt constraint
(page 2–406).
Note: A targeted object’s pitch and heading
are adjusted by moving the target, so the only
