This daemons creates a scalable box to delete particles from inside or outside a bounding volume (see "Falloff" for adjusting this volume).
RealFlow Scene
In RealFlow | Cinema 4D it is possible to use multiple "Scene" trees in the same project. To link a daemon to a different scene tree drag the appropriate "Scene" node to this field.
Linked
All fluid, rigid, and elastic containers inside the drag-and-drop field will be affected by the daemon. The first container in the scene is linked automatically, others have to be attached manually.
