Morph Controllers 295
Point3: A general-purpose, three-component data
type that works with RGB color values. It uses
most of the standard controllers.
Color: A special data type designed specifically for
working with RGB and HSV color va lues. Color
uses the Bezier and RGB controllers.
Color Point3 Controll er
You can assig n any of a variet y of Point3 controllers
to a material’s colo r channels, including Point3
Expression, Point3 List, Color RGB (described
later in this topic), and so on. When using Point3
controllers for color parameters, an important
issue is behavior of the Key Value fields, labeled X,
Y, Z. They store color values using only the RGB
color model.
•TheXvaluefieldstoresRedcolorvalues.
• The Y value field stores Green color values.
• The Z value field stores Blue color values.
ThePoint3KeyValuefieldsdonotclampatthe
valid color range of 0 to 255. Values that drop
below 0 or exceed 255 are ignored by the color
parameter but are still displayed in Track View.

The Color Value fields are limited to a range of
0 to 255. You can dr ag the color keys above 255
in Track View Curve Editor, but the values are
clamped at 255.
Color R GB Controller
Assign a Color RGB controller (page 2–311)
to break a Color controller into three separate
Bezier Float controllers. Each of the R, G, and B
components of color uses its own track.
Use the Color RGB controller when you want to
have separate key patterns or controller types for
each color component.
Morph Control ler s
You can choose from two morph controllers: Cubic
and B arycent ric; they manage how morph targets
blend from one target to another. Morphing can
also be achieved by applying a
Morpher modifier
(page 1–721)
to an object.
Cubic M or ph Co ntr oll er
ACubicMorphcontrollerisaTCB-style
controller. I t uses Tension, Continuity, and Bias
controls much like the generic TCB controller.
The Cubic Morph controller manages only the
interpolation from one morph target to the next. If
you w ant to add Morph keys or change the morph
target, you must use the
Pick Targets and Current
Targets rollouts (page 1–309)
in the Modify panel.
B a r y cent r ic M or ph Control ler
The Barycentric Morph controller (page 2–304)
is also a TCB controller like the Cubic Morph
contro ller, except that instead of each key
representing a single target, each key represents
a series of weights for all targets. A Barycentric
Morph key represents a new object which is a
blending of all targets.
You can adjust each morph key to percentages
of the available morph targets, creating subtle
adjustments in the animation.
