The following image shows the default Emitter settings.
Note: For particle emitters with multiple cells, some Dashboard parameters are
displayed as percentages, so that adjusting the emitter parameters simultaneously
modifies the effect of each cell’s parameters relative to one another. For example,
adjusting the Scale parameter for an emitter with three different particle cells, each
with a different Scale value (set in the Particle Cell tab of the Inspector), resizes all three
cells relative to their original Scale values.
Continuing with the jellyfish example, the following section describes the Emitter
Dashboard controls.
Birth Rate: This slider represents a percentage or value, based on the Particle Cell Birth
Rate, of how many particles are created every second.
Life: This slider defines how long (in seconds) each particle remains onscreen before
disappearing.
Scale: This slider defines the size of each particle, relative to the original size of the cell.
Emission Range: Controls that you can drag to define the Emission Range for the
particles. Think of the Emission Range as controlling the size of the slice of the 360-
degree “emitter pie.”
Drag one of the white lines in the
Emission control to define the
Emission Range.
