Motion Clip Slave controller
The Motion Clip Slave controller lets a linked motion clip that is loaded and defined in the Motion Mixer
control the object’s transform.
Motion Capture controller
The Motion Capture controller allows you to control an object’s transforms using an external device such as
a mouse, keyboard, joystick, or MIDI device. This controller works with the Motion Capture utility to cap-
ture motion data.
After you assign the Motion Capture controller to a track, right-click the track and select Properties from
the pop-up menu to open the Motion Capture panel, shown in Figure 34.19. This dialog box lets you select
the devices to use to control the motion of the track values. Options include Keyboard, Mouse, Joystick,
and MIDI devices.
