5 In the Event 02 > Scale operator, set Type to Absolute, and animate the
Scale Factor values from 10 to 100 over frames 0 to 30. In the Animation
Offset Keying group, set Sync By to Event Duration.
6 Add an Age Test to Event 02. Set it to Event Age, set Test Value to 30, and
Variation to 0.
In this event, particles grow from 10 percent of their original size to full
size over the first 30 frames of their existence, which is the same as their
duration in the event. At that point, they'll be eligible to move to the
next event.
7 Use a new Scale operator to create a new event, Event 03. Set the new
event's Display operator to Geometry, and make sure it's a different color
than the others.
8 Wire the Age Test in Event 02 to Event 03.
9 In the Event 03 > Scale operator, Set Type to Absolute, and in the
Animation Offset Keying group, set Sync By to Event Duration.
10 Copy and paste the Age Test as an instance from Event 02 to Event 03.
Particles in Event 03 remain at full scale for 30 frames, and then move
on to the next event.
11 Use a new Scale operator to create a new event: Event 04. Set the new
event's Display operator to Geometry, and make sure it's a different color
than the others.
12 Wire the Age Test in Event 03 to Event 04.
13 In the Event 04 > Scale operator, set Type to Absolute, and animate the
Scale Factor values from 100 to 10 over frames 0 to 30. In the Animation
Offset Keying group, set Sync By to Event Duration.
14 Copy and paste the Age Test as an instance from Event 03 to Event 04.
In this event, particles shrink from full size to 10 percent of their original
size over 30 frames.
15 Play the animation.
Next, you'll use a Noise controller to cause the particles in Event 03 to
pulsate in size.
16 Add a second Scale operator to Event 03, below the existing Scale operator.
Set it to Relative Successive, and set Sync By to Event Duration.
The name of this operator should be Scale 04.
