Clouds are graphical effects in the sky. They serve a solely aesthetic purpose.
The appearance of clouds varies depending on the graphics settings used:
Fancy: Clouds are translucent, three-dimensional prisms, approximately four blocks tall and 12x12 blocks wide. At night they turn a shade of blue and become more transparent. They are similar in appearance to stratocumulus clouds.
Fast: Clouds are two-dimensional and opaque. They have no day-night rotation. Their smallest horizontal dimensions are 8×8 blocks wide. Fast clouds in Bedrock Edition are also opaque, but remain three-dimensional. Their appearance is similar to cirrus clouds.
In Legacy Console Edition, clouds consist of 3×3 block sections, which form the same pattern of clouds found in other editions.
From above or inside the clouds, they will appear semi-transparent, regardless of the player's graphics settings. The sun and the moon will always appear visible through the clouds from below, even if there are blocks that would otherwise block its view[verify].
The shape, dimensions, and color of clouds can be changed by modifying the
clouds.png file located within
assets\minecraft\textures\environment within the version's JAR file. The file's dimensions can be changed to any size, allowing for different cloud patterns each day.
Clouds always float westward between layer 100 and 150 based on the viewer's height. They are not interactive, and simply float through blocks and entities. Unlike in real life, clouds themselves will not produce rain or snow, meaning it will continue to rain or snow even above the clouds.
Since clouds are are rendered client-side, the position of clouds is different for each player on a server.
Clouds will retain their position even if the game is restarted. The position of clouds is persistent between worlds — if the player quits their current world and generates a new one, then travels to the same coordinates they were at in the previous world, the clouds will be seen in the same position as the previous world. Switching between Fast and Fancy graphics will randomize the position of clouds
Clouds can be toggled between Fancy, Fast, and Off in the Video Settings.
|May 23, 2009||Notch says he accomplished adding "Clouds two tiles above the maximum build height".|
|0.0.14a||Added clouds, which float northward between layers 108 and 112.|
|June 15, 2010||A Fast/Fancy graphics setting is added, which toggles clouds between two- and three-dimensional. Fancy clouds use a different texture:|
|June 24, 2010||Removed that texture.|
|1.8||?||The cloud layer was raised to layer 127.|
|1.0.0||Beta 1.9 Prerelease 4||Clouds now float towards the west.|
|Beta 1.9 Prerelease 5||Clouds can now be disabled in the Video Options menu.|
|1.2.1||?||Build height increased to 256, allowing for players to build much further above clouds.|
|1.8.1||?||The clouds' "Fast" and "Fancy" shape are controlled with the same option that enables clouds, rather than with the standard Fast and Fancy graphics.|
|Upcoming Java Edition|
|1.13||18w10d||Big optimizations to how clouds are rendered.|
|18w14a||The rendering of clouds has been optimized again.|
|Pocket Edition Alpha|
|0.6.0||Added clouds. Clouds could only be seen in Fancy graphics, and if so, the clouds appeared opaque and two-dimensional, similar to the Fast clouds seen on Java Edition.|
|0.7.0||Clouds are now toggled with the Beautiful Skies option.|
|0.7.4||Clouds now have a darker color to match Java Edition.|
|0.8.0||build 2||Clouds are always three-dimensional, and are opaque and transparent with Fast and Fancy graphics, respectively.|
|0.9.0||build 1||New culling of clouds.|
|Clouds have been made prettier.|
|0.10.0||build 1||New double-sided lighting on clouds that's more coherent with the terrain.|
|build 6||Better fog on clouds, starting farther away and following the sky color.|
|build 7||The clouds and the terrain are now tinted red during sunset.|
|1.0||?||Build height was increased to 256, allowing for players to build much further above clouds.|
|Legacy Console Edition|
|TU1||CU1||1.0||Patch 1||Added clouds.|
|TU5||Cloud height raised to the top of the map, so clouds can no longer phase through blocks.|
|Cloud movement syncs with the game's time.|
