Drift Sets how flames are rendered along the Z axis of the fire apparatus. The
value is the amount of rise in units.
Low values give a slow-burning cool fire.
High values give a fast-burning hot fire.
For the best fire effects, drift should be a multiple of the height of the fire
apparatus.
You can also animate the location and size of the fire apparatus and most of
the fire parameters. For example, a fire effect can animate color, size, and
density.
Explosion group
Use the parameters in the Explosion group to automatically animate
explosions.
Explosion Animates size, density, and color automatically based on the
animation of the Phase value.
Smoke Controls whether or not the explosion creates smoke.
When on, fire colors change to smoke between Phase values 100 to 200. Smoke
clears between Phase values 200 to 300. When off, fire colors remain at full
density between Phase values 100 to 200. Fire fades away between Phase values
200 to 300.
Fury Varies the churning effect of the Phase parameter.
Values greater than 1.0 cause faster churning. Values less than 1.0 cause slower
churning.
Set Up Explosion Displays the Set Up Explosion Phase Curve dialog. You
enter a start time and end time, and then click OK. The Phase value animates
automatically for a typical explosion effect.
