Star Wars: Way of the Jedi, will be a two part mod, for single player Jedi Academy. (with possibly a few bonus maps for multiplayer) It will contain many new levels, and will bring back JKA's Tier based mission selection system, this time with even more choices, as well as the upgradeable force powers and weapon selection. The main character will be Alex Jarrons a relatively new student at the Jedi academy, who will travel throughout the galaxy. Eventually, you will have to come to a decision and choose; between your friends and ultimate power.

? Okay.... I can if you want, but why?
There is no point in making the sky too far from upper levels of the buildings, if its textures+shader only. However, if You use FX files (e.g. like on Bespin levels from JO) as well as sky_portals, then it's worth doing as dvg94 says.
