Optional cloudsOptional skyProcedural sky colors. They also drive the ambient lighting, also while skybox_texture is set.
While skybox_texture is set they no longer color the visible sky.
Optional skyboxReplaces the visible sky with an image, given as its source path with the same rules as Texture.src.
It must be an equirectangular (latitude-longitude) image with a 2:1 aspect ratio:
the image centre faces +Z, the top row is the zenith and the bottom row the nadir.
Cube cross, 3x2 and six-face layouts are not supported.
The sun, the fog and the ambient lighting do not change: the ambient still follows sky_colors.
Optional starsIgnored while skybox_texture is set.
