How do I add a skybox into the game

Iv found the 2 sky styles that come with the program but I dont know how to add them into the scene or anything.

Also, does any one know where I can download a nighttime one

 

You should do some searches here on the forum and look through the docs before diving into a 1001 questions

There are two ways to add a skybox:

one - add a skybox render component to your camera
two - add the skybox in the render settings

the second is easier if your game only ever uses one skybox. The first one allows you to have different skyboxes on different levels without having to script the change.


I'm selling skyboxes for Unity and have a couple night-time ones in the collection, see link below. You can also render your own or use Google, though good skyboxes are a bit tricky to find if you're looking for something specific.
