[LVL ED] How to install a skybox?

[Mackiiboy]

Hi i'm currently working on an outside map and i require a skybox. But i got no clue how to install it.
If someone got the sparetime to go into details how to propertly install it, that would be a lot to me.
Also the skybox i'll be using is the night one where you can see the moon.

Thanks in advance ,

In HPL Level Editor, Press Edit in the menu, Level settings -> skybox, and press on the [...] and choose the right texture you want to use as a skybox. Mark the Active [X] box, and your skybox will appear in your map.
Good luck
