This daemons creates a scalable box to delete particles from inside or outside a bounding volume (see "Falloff" for how to adjust 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.
Links
All fluid, rigid, and elastic containers inside the drag-and-drop field will be affected by the daemon. If there is only one container in the scene it will be linked automatically. Otherwise the connection has to be established manually.
