	In TDM 2.08, a new spawnarg parallelSky was added. If you add it to a parallel light (see visual example below) and set value "1", then the light will emanate from every visleaf containing surfaces with textures/smf/portal_sky material. This usually includes all outdoors area automatically. Note that other (i.e. indoors) areas are also included if they can be reached from outdoors areas through open visportals, so the light should work correctly indoors if someone opens a door.

			The main problem with parallel light is that: while it does not radiate light rays from the light origin, the origin still matters when engine flows light rays through visportals. An ordinary parallel light always works properly in the visleaf where its origin is located. In addition to that, it takes effect in all the other visleafs which can be reached from the starting visleaf through visportals by travelling along the direction of the light. So in order to create a global moon/sun light which will light many outdoor areas, one has to create a separate visleaf above the outdoor areas, which would contain the light and have portals leading down to every outdoor area below. It is quite complicated.
