How to hide skybox in Planet Studio?

@Zenithspeed
yes that’s the exact name

if you mean the daytime skybox, just enable the "Fade Skybox During Daytime" (it's called something similar to that, idk exact name) at the basic stuff tab (one with name, version, description, radius, gravity, etc.)
however if you want it always hidden, go into the game settings and set "Star Brightness" to whatever you wish, or zero for a completely black skybox
