Select the rotation track. Euler XYZ is assigned as the default controller.
The Euler XYZ Rotation controller is a compound controller that combines
separate, single-value float controllers to specify an angle of rotation about
each of the X, Y, and Z axes. Euler XYZ is not as smooth as quaternion rotation
(used by the TCB Rotation controller), but it is the only rotation type that you
can use to edit rotation function curves.
The Euler XYZ Rotation controller assigns individual tracks to the X, Y, and
Z components of position, rotation, and scale transforms. However, the
controller assigns three keys (one for each axis), by default. To avoid this, you
can use
Customize User Interface on page 7697 actions to create explicit axis
keys. These are available in the Main UI group > Set Key Tools category.
The Gimbal reference coordinate system on page 973 is intended for use with
this controller. With other coordinate systems, rotating about one axis always
changes at least two tracks. With Gimbal rotation, rotating about one axis
changes only one track, making it easier to edit function curves.
Euler versus TCB Rotation
Euler rotation offers several advantages over the TCB Rotation controller,
which was the default rotation controller prior to 3ds Max 5. Euler rotation
provides function curves, while TCB does not. Euler rotation allows for three
separate curves that can be manipulated in the Curve Editor. TCB rotations
can be controlled only with tension, continuity, and bias settings, making it
difficult to keyframe and manipulate X, Y, and Z rotation independently.
