The Boolean controller can be assigned to any parameter that would normally
be controlled by a float or boolean class controller, such as a sphere's Hemisphere
or Smooth track.
Boolean controller key values can be changed in on of two ways: through
Track View's Dope Sheet editor or through MAXScript.
NOTE Although the Boolean controller displays a function curve in Track View's
Curve Editor, it does not display keys. Key time and value must be changed in the
Dope Sheet editor.
Procedures
To assign a Boolean controller and add keys:
1 Open Track View's Dope Sheet editor and select any track that would
normally be assigned a float or boolean class controller.
2 Right-click and select Assign Controller. Pick the Boolean controller from
the Assign Controller dialog, and click OK
3
From the main Track View toolbar, select the Add Keys button and
click anywhere on the selected track.
New keys with a value of 0.0 are added.
To change Boolean controller key values in Track View:
1 Open the Track View Dope Sheet editor and select a track that contains
a Boolean controller.
2 Select any key and type 1.0 or 0.0 into the key value field at the bottom
of the Track View dialog.
NOTE Values greater than 0.0 will automatically be clamped to 1.0
