hey, if you want I can get you a version of the skybox without the built in map star. I didn't realize at the time that you couldn't manually set the sun flare to below horizontal because I had only tested it with simple settings which works for that.
Or that map star as the sun flare
Attached is the skybox part for no built in star. Just replace the one that has the star in the Sky_SPAAAAAAACE.zip folder with this one, and name it accordingly
