Portal extent. Defines the dimensions of the portal relative to its center; all components must be positive numbers. The local X and Y dimensions (side and top) are used in diffraction calculations, whereas the Z dimension (front) defines a depth value which is used to implement smooth transitions between rooms. It is recommended that users experiment with different portal depths to find a value that results in appropriately smooth transitions between rooms.
