The Particle Editor is the primary tool for creating special effect, from explosions to magical spells. To create such effects, the Particle Editor creates Emitters which are composed out of different Particle Sources. There is no limit as to how many particle Sources can be attached to an Emitter. This allows for a much faster development workflow. For example if making a fireplace effect, you can have the flames, sparks and smoke all contained within one Emitter and still be able to edit each part individually, instead of creating multiple emitters and lining them up in the World Editor.
