The Bezier Float controller is a single parameter
controller.
Note: The Color RGB and the Point3 XYZ
controllers are identical in function, except that the
labels of their tracks are R GB and XYZ respectively.
P oint3 XYZ controllers can be used for functions
such as Noise Strength, and the FFD modifier.
Procedure
Example: To animate the back ground color of a
render ed a nimati on:
1.
Open Tr ack View – Curve E ditor.
2. In the Track View hierarchy, expand the
Environment track and then select Background
Color.
3. On the Track View menu, click Controller >
Assign and select the Color RGB controller.
4. Expand the Background Color tr ack.
5. On the Track View toolbar, click Add
Keys.
6. Add three keys along the red track at frames
0, 50, 100.
7. Right-click one of the keys to display the Bezier
Float dialog. Change the key values to 0, 400,
and 0, respectively.
To see the background color change, mov e the
timeslidertothesameframeasthekeythatis
being adjusted and render the scene. To see the
color change in an animated fashion, you must
render the animation.
Although you can set values over 255 in the
value field, the actual color value stops at 255.

The Euler XYZ Rotation controller is a compound
controller that combines separate, sing le-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 quater nion rotation (used by the TCB
Rotation controller), but it is the only rotation type
that you can use to edit rotation f unction curves.
The Euler XYZ Rotation controller assigns an
individual track to the X, Y, and Z components
of the position, rotation, or scale of an object.
However, the controller assigns three keys (one for
each axis), by default.
