Planet and Background replacer and lots of new ones. version 1.2.1 with 21 new backgrounds and 14 new planets. Version 1.3 adds 62 new HUBBLE backgrounds. Version 1.3.1 adds new stuff and color fixes.
This Mod replaces the Textures for the Asteroids and the ion storm lightning.
Can I just download this one or so I have to download 1.2 and 1.2?
this will only replace the asteroids, so you also have to use 1.2 or 1.3 for planets and backgrounds.
Will I need to use this with 1.3.1 or is it already included?
it's not included in any version. use it if you want asteroids replaced, don't use it if you want unmodded asteroids.
