The On/Off controller is assigned to tracks providing only binary on and off control. For example, the Smooth check box in creation parameters or tracks.
You can view the curve for this controller in the Function Curve display, but it's not editable. In addition, there's no Properties dialog for this controller.
Note: When you load a scene from gmax that contains a Visibility controller, the controller is automatically converted to an On/Off controller.
Procedure
Example: To use the On/Off controller:
Create a cylinder, and display the Smooth track in Track View.
Turn on Animate, move to frame 20, and turn off Smooth.
From frame 0 to 20, the track appears blue up to the new key dot, and gray following the key dot.
Move to frame 30, and select Smooth.
The track is now blue again following frame 30.
Click Add Keys in Track View, and click to add some keys in the Smooth Track. Each added key reverses the on/off blue pattern following the added key.
In this case, an On/Off Controller is added to the Smooth Track automatically.
Tip: You can select 2 or more keys and copy them to different positions. This allows you to create even intervals for the On/Off effect.
Interface
You assign the On/Off Controller in Track View.
In Track View, the On/Off track displays a solid blue color in frames that are On, and no blue in frames that are Off. When you add a key to an On section of the track, the section following that key is turned off. When you add a key to an Off section, the following section is turned on and colored blue.
