are compound controllers. They set the type and behavior of the
controllers used for Position, Rotation, and Scale.
You assign Transform
controllers using either Track View — Curve Editor or the Motion
panel. Compound Transform controllers do not display properties
in Track View. You can access the parameters of Transform controllers
only in the Motion panel.
(PRS) controller is a simple Transform
controller applicable for most objects. When applied the PRS Transform controller
sets up default Bezier Position, TCB Rotation, and Bezier Scale
Use a PRS controller
whenever you want a standard transform set up or when you want single
function curve control over the Position, Rotation, and Scale controllers.
NotePRS controller is
no longer the default controller applied to all objects. The latest
version of 3ds Max Design uses Position XYZ and Euler XYZ as the new
default controllers for position and rotation transforms.
Transform Script Controller
Script controller contains
all of the information contained in a PRS Controller in one scripted
matrix value. Instead of having three separate tracks for position,
rotation, and scale, all three values can be simultaneously accessed
from one script controller dialog. Because the transform values
are defined by a script, they are easier to animate.
The value of the controller
script must be a matrix3 value. A matrix3 value is a 4x3 3D transformation
matrix. For more information, see the Matrix3 Values topic in the
controller lets you externally reference
any type of Transform controller from another scene file. When you
assign this controller to your object, it nests the source controller,
making it only accessible for playback. You can use the XRef controller
either on its own, or combine it with an
