17 In Particle view, right-click the Scale Factor X % parameter field on the
Scale 04 rollout, and choose Show In Track View.
The Curve Editor opens with the X Scale Factor parameter highlighted.
18 Right-click the X Scale Factor item and choose Assign Controller from
the menu.
19 In the Assign Float Controller dialog, double-click Noise Float.
The Noise Controller dialog opens.
20 Set Strength to 200, and to the right of Strength, turn on the >0 check
box.
21 Copy this controller, and then paste it as instances to Y Scale Factor and
Z Scale Factor.
Although the Scale operator defaults to constraining all scale factors to
the same value, thus scaling particles uniformly, changing controllers in
Track View works on a per-parameter basis.
22 Play the animation.
This time, the particles grow in size for 30 frames, then pulsate in size
for the next 30 frames, and then shrink from the size at the end of Event
03 to 10 percent of that over the next 30 frames.
