The viewport displays the currently loaded emitter with all settings applied. By holding and dragging the Left Mouse Button within the viewport area it is possible to rotate the camera around the Emitter. The Scroll Wheel can also be used for zooming in and out.
Particle List – Under the Emitter list is the Particle List. This is a list of all the particle sources within the currently loaded Emitter. You can hide/show each particle source by changing the check state of the checkbox for each item in the list. Particle Sources can be renamed by clicking on their text once and then typing in a new name, then pressing the enter key to save changes, or Esc key to cancel. By selecting an item from the Particle List, its corresponding settings will be loaded, ready for modification.
