I have searched how to alter the backgrounds and sky boxes of space maps, but I have had little luck. It does not seem to be as clear and easy to do as a regular ground map. Any tips or tricks? Thank you!

If you just want to use one of the other stock configurations you can go to line 181 of your ABCc_cmn.lua and change the 3 character abbreviation in quotation marks to something listed in data_ABC\Worlds\ABC\sky\spa_sky.req, for example if you wanted to use Coruscant's: otherwise you can just keep what you have and change only the parts you want to reconfigure, such as textures etc.

You could also change the whole sky file situation to look the same as how the "land map" skies are set up by combining all of your sky configuration into the ABC.sky file in your world1 folder, no sense in having all those skies if you're only using one.
