To fill all holes with new rooms, set the area threshold to zero. To have all holes merged into neighboring rooms, set the area threshold to a high number * **Courtyard Threshold** The area above which a hole is considered a courtyard and therefore should not be filled at all. To have all holes in the selection filled regardless of how large they are, set this value to a negative number (or any number smaller than the Area Threshold). * **New Room Name** Text to set the name of newly-generated rooms. In the case of multiple holes being filled, this input will be a base name and an integer will be automatically added to the end of each new room name
