So I need to create a custom skybox texture for a map I am working on. It is very simple, its just a space skybox, with a black sky and white dots for stars on it. I am just wondering if there is anything special I need to keep in mind when making it? What size should each piece be? I am guessing 512x512 but I have no idea. Do I need to save it a special way before converting it to VTF, etc. Anything in paticular I need to set in the VMT file, or is it fine just setting it up like a normal texture?
