I am making a large skies pack, witch uses some ported skies from tribes2, and a bunch of custom player made skies for tribes2 and more. I'm not going to take credit for the pack or its name, a lot of the content is copyright. this pack will be useful to some mappers you may want to use skys from it in their map. Then just tell the player they need this pack to play.
The directory for all the skies will be this...
legions\data\mod\skies
