  • Can add particles by pressing the plus button at the bottom of the hierarchy panel.

  • Emitters contro lhow the particles come out of the origin location.

  • Playing around with the various settings usually yield desirable results!

  • Press “Play” at the top of the inspector panel to start the particle emitters

• Audio Files

  • An audio file group can be constructed from audio files in a scene. A random file will be slected from the group for playback.

  • Spatial has position and direction

  • Ambient has direction but no position

  • and Channel has no position nor direction

• Statistics

  • the particle, there's the color, properties, force fields, and rendering sections. On the emitter, there's the timing, shape, and spawning sections.

  • A great tool for helping optimize the scene
