Setting Channel Editor Properties
The Channel Editor includes the particle properties included in the Particle menus for which you can set values and create particle animation effects. You set these properties in conjunction with those located in the Particle Generator, Particle Manipulator, and Particle Bouncer menus.
You must first add a particle generator, a particle manipulator, or a particle bouncer to the scene to view and set values for their corresponding properties in the channel hierarchy of the Channel Editor. See Accessing the Channel Editor.
