You CAN use the same emitter which also generates the source particle, but it is usually a bad idea. It has the advantage that you can set the parameters of the spawned particles to be quite different from the source particles. In general, it is recommended that you use a second emitter for this purpose.

Without an emitter in this field you cannot access any of the other parameters and the modifier will have no effect. This is the emitter which will generate the spawned particles. The modifier's effect on a particle can be halted by means of another Action, if desired. Until that point, the particle will not be affected, but once activated for a particular particle, the modifier will continue to influence it as long as it is in the field of effect of the modifier.

In this mode, the modifier will only act on a particle when told to do so by an Action. X-Particle Actions have no effect on the modifier in this mode. In this mode, particles will be affected if they come into the field of effect of the modifier. Uncheck this switch to disable the modifier. This modifier contains the following sections:įor the 'Groups Affected', 'Mapping', and 'Falloff' tabs, and for the buttons at the bottom of the interface, please see the ' Common interface elements' page. This modifier will cause particles to spawn from existing (source) particles.
