Sky, clouds & weather
Skies, clouds, day-night cycles, rain, snow and fog set the atmosphere of an outdoor scene. These guides cover procedural skyboxes, stylised and volumetric clouds, weather systems and wetness effects. Several of them show how to keep the cost low on mobile. 26 hand-picked Unity guides, tutorials, videos and repos, kept current.
