The Scene Options section shows all options relating to the current scene.

Primarily this section will be used to choose which Particle Flocker Node is currently being edited by the Particle Flocker Window.

The currently edited Particle Flocker is shown in the Current Particle Flocker Node drop down menu. If there are multiple Particle Flocker nodes in the scene, changing the selected item in the drop down menu will update the Particle Flocker Window to reflect the newly selected node.

You can also create new Particle Flocker Nodes from this section by pressing the Create New Particle Flocker Node button.

The Refresh UI button will rebuild the Particle Flocker Window, and is occasionally needed if you have closed or opened a scene while the Particle Flocker Window was open. This can leave some of the UI elements disabled and needing to be refreshed.
