Xonotic Forums

I've recently been working on a map and have just discovered the skybox I was using was not a stock Xonotic one but was instead tied to a particular map (dissocia) - I don't know the license status of that skybox so I don't know if I would be allowed to package it with my map. I also can't find more details on that map that might resolve this.
So, I'm looking to source or create a new skybox. The needs are simple enough - dark stormy clouds. Anyone know any good candidates or any good tutorials that might help me make one myself?

Maybe this will help you create your own Skybox :

Hipshot skyboxes are there:

Oh, I have found it:

https://wwwtyro.github.io/space-3d/#anim...&sun=false

Skyboxes generated by that tool are acceptable to use. The tool itself is licensed under the unlicense. Source.

Seems that it's amazing how skybox can be created inside game. The tutorials from DarkFox are good!
