1.
Click to activate the the “Size over Lifetime” module and then click on its title
bar to open it.
By default, it is set to a Curve.
Click on the mini-curve to see a larger view. This curve will affect the Start Size of the particles,
so 1.0 at the top left equates to 100% of the Start Size.
2.
Position the cursor over the middle of the curve, right-click, and select
Add Key.
3.
A key with Bezier handles is created on the curve.
Time, at the bottom, is on the horizontal and represents 100% of the Start Lifetime of the particle.
4.
Select the key at time 1.0, and drag it down to 0.5 to make the particle
smaller at the end.
The plume of smoke is a bit too broad midway up. The “Size over Time” module is a good place to
adjust it.
5.
Drag the key you created down to about 75% (Figure
8-27
).
