angle of rotation about each of the X, Y, and Z axes. Euler XYZ Rotation is
the default controller applied to all objects.
Euler XYZ is not as smooth as quaternion rotation, but it is the only rotation
type that you can use to edit rotation function curves.
Euler angles are well suited for animating mechanical rotations. They can also
be a good choice for an object in an inverse kinematics chain because IK
Rotational joints are defined as Euler angles. X, Y, and Z function curves
displayed by this controller in Track View represent rotations in "world" or
"parent" space which is the rotation system used by most 3D animation
packages.
Customers upgrading from earlier versions of the program might find some
difficulty in adapting to using Euler XYZ rotation controllers. If you find
yourself experiencing unexpected rotation behavior, this might be the reason.
Reassign TCB rotation as the default rotation controller and you will be able
to regain your customary workflow.
Controlling Colors
You can animate colors in 3ds Max just like most other parameters. Two data
types are available for controlling colors:
■ 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 values. Color uses the Bezier and RGB controllers.
Color Point3 Controller
You can assign any of a variety of Point3 controllers to a material's color
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.
■ The X value field stores Red color values.
■ The Y value field stores Green color values.
■ The Z value field stores Blue color values.
