Emitter
Attribute manager settings
Particle Tab
Birthrate Editor
Denes how many particles per second are to be created in the viewport. The particles are emitted
randomly from the entire surface of the emitter.
Birthrate Renderer
Denes how many particles per second are to be created in the renderer. The particles are emitted
randomly from the surface of the emitter.
Visibility
Denes how many of the particles should be visible. At rst glance, this appears to offer no more than
the birthrate settings. However, it is not possible to animate some of the parameters in the particle
system, such as the birthrate settings. If you want to vary the intensity of the particle stream over
time, animate the Visibility setting.
Start Emission, Stop Emission
Use these values to dene when (in frames) the particle emission should start and end.
