Auto-orient along Motion Path Causes an image to rotate according to its motion direction at any given time.
This is useful when animating an object that should always point along the path
of motion, such as an airplane (see illustration on page 76).
The “Forward Motion Direction” options control the orientation of the image as
it moves along the motion path. Choose the direction you want to be consid-
ered forward, with the default value being the right edge of the image (X+).
NOTE: In some cases you may also need to apply Rotation to the image to
make it point in the desired direction.
External Control of Position,
Rotation and Scale
Usually, you control image position, rotation and scaling using the corre-
sponding tween tracks alone. However, you may occasionally want to control
these parameters from an external source, such as a MIDI or DMX input, or via
the network (see “Inputs” on page 197). Select this checkbox to allow for such
external control. Add the desired tween track and use its formula button to
assign the control source to the desired parameters (see “Controlling Tween
Tracks” on page 202).
IMPORTANT: Selecting this option significantly increases the load on all
your computers. Do not choose this option unless necessary.
NOTE: For still images, this option is only available when “More Effects and
Capabilities” is selected for the image (see page 36).
