The birthrate defines the rate at which new particles are emitted by the node. The greater the value the faster new particles are generated, though it is recommended that the minimum number of particles needed to achieve the desired effect be used to avoid performance degradation. The total number of particles to be emitted may also be specified. A value of zero causes particles to be emitted indefinitely. If a limit is specified the node will stop emitting particles when that value is reached.
