[Particles]
iMaxDesired
iMaxDesired sets the maximum amount of particles "desired" to be rendered. This affects smoke, sparks, lights, and similar effects. The way it is designed, if set to 0, most of the time particles will not be seen, but sometimes they will "flare up," hence the "desired" part. Extremely high values can cause some windy snowstorms to become a little too severe.
Default is 750.
iMaxDesired=(...,-1,0,1,...)
