Size Over Lifetime Module
Many effects involve a particle changing size according to a curve, which can be set in this module.

Details
Particles that represent gases, flames or smoke will typically change in size as they move away from the point of emission. For example, smoke will tend to disperse and occupy a larger volume over time. This effect can be achieved by setting the curve for the smoke particle to an upward ramp, increasing with the particle’s age. (The effect is enhanced if Color Over Lifetime is also used to fade the smoke as it spreads.) For fireballs created by burning fuel, the flame particles will tend to expand after emission but then fade and shrink as the fuel is used up and the flame dissipates. In this case, the curve would have a rising “hump” that then falls back down to a smaller size.
