Everything you animate in gmax is handled by a controller. A controller is a plug-in that handles the storage and interpolation of all animated values.
Although the program has many different types of controllers, most animation is handled by the Bezier controller. Other controllers exist to provide you with animation options and special animation techniques. You can also add to the available controllers by acquiring new controller plug-ins, extending the program's animation capabilities.
This section explains techniques of working with controllers. See Animation Controllers for details about the parameters and use of each controller type. Following is a list of topics in this section:
