A sector is a cuboid shaped object that culls all objects outside its volume. Sectors usage is very convenient for designing of indoor spaces. Sectors are connected by portals.

By default, shadows from the culled objects remain visible. To disable shadows rendering, go to Windows -> Settings -> Occlusion Culling and enable Shadows Culling or run the console command render_occluders_shadows 1.
