Working with Emitter Objects

An emitter includes one or more particle types and many properties. Several of its properties are scaling factors (or master parameters) that scale the corresponding particle type properties.

For example, an emitter has two particle types: Stars and Squares. Stars has a Velocity of 40, and Squares has a Velocity of 15. If the emitter's Velocity scaling factor is set to 200%, the effective velocity for Stars is 80 and for Squares is 30.

Note: Changing an emitter scaling factor makes no difference to the particles if the corresponding particle type property is set to 0.

Unlike particles, emitters can be controlled directly and moved over time. You work with emitter objects like you work with objects in the Paint operator.
