{{for|the command {{in|bedrock}}|Commands/fog}}
'''Fog''' is a rendering feature intended for obscuring the player's view distance, usually for atmospheric effect or for seamlessly occluding sharp boundaries such as unloaded [[chunk]]s. While traditionally referring to [[render distance]], there are many other types of fog that can be encountered in-game under specific circumstances.
== ''Java Edition'' ==
=== Fog types ===
There are four fog types, each occurring in four different circumstances.
==== Distance fog ====
{{conjecture|section=1}}
This refers to fog that is rendered in normal circumstances, and becomes the most notable with low render distance.
The sight distance in the distance fog is equal to the render distance, and the shape is a cylinder. Its color depends mainly on the [[biome]] the camera is in, and is affected by:
* the current day-time, and the [[Effect (dimension)|effect]] the dimension uses
** For the Overworld effect, the brightness of the color changes with day time.
** For the Nether effect, the brightness of the color is ''not'' affected by day time.
** For the End effect, the brightness of the color does not change with day time, but is 15% of the biome fog color.
* the current sky color, and the render distance
** The smaller the rendering distance, the closer the color of the fog is adjusted to the sky color.
** When the rendering distance is 32, the color of the fog is not affected by the sky color.
* the direction the player is facing during a sunrise or sunset if the render distance is not less than 4
* the current [[weather]]
==== Water fog ====
When the camera is in [[water]], a dedicated fog in the shape of a cylinder is applied to simulate this. Underwater fog progressively recedes with time spent underwater. The color depends on the [[biome]] the camera is in. The color of the water fog changes gradually for 5 seconds when the camera traveled in water into another biome. Notably, [[swamp]]s and [[mangrove swamp]]s have a thicker fog than most other biomes, which is controlled by the biome [[tag]] has_closer_water_fog.
==== Lava fog ====
When the camera is in [[lava]], an even thicker fog in the shape of a sphere is applied. Its color is RGB(0.6,0.1,0.0). With this fog, normally the player can see only 1 block away. The [[Fire Resistance]] effect can mitigate the fog so that the sight distance becomes 3 blocks. In [[Spectator]] mode, the fog is even less opaque to reveal objects located within up to half the render distance.
==== Powder snow fog ====
Being beneath [[powder snow]] imparts another fog in the shape of a sphere. Its color is RGB(0.623, 0.734, 0.785). With this fog, normally the player can see only 2 blocks away. In [[Spectator]] mode, the fog becomes thinner so that things within half of the render distance are visible.
=== Fog modifiers ===
==== Height ====
If the world is not a [[superflat]] world, and the camera is not in lava and not in powder snow, the brightness becomes power(clamp((y-minY)*0.03125,0.0,1.0)) of the original, which means that the color changes to pure black gradually from minY+32 to minY.
==== Blindness and darkness ====
[[Blindness]] and [[Darkness]] set the color to pure black. The sight distance with Blindness is 5 blocks, while the sight distance with Darkness is 15 blocks. Also, the shape of the fog becomes a sphere.
A difference between the two is that Darkness has fade-in and fade-out, while Blindness has only fade-out.
Blindness has a higher priority than Darkness. The two effects do not work if the camera is in lava or powder snow.
==== Wither ====
If there is a [[wither]] boss event, the color becomes darker and slightly redder.
==== Night Vision ====
If the camera is not in water, and the entity has no [[Darkness]] effect, [[Night Vision]] makes the color brighter.
==== Nether and ender dragon ====
If the entity has no Blindness or Darkness, in a dimension with the Nether [[Effect (dimension)|effect]], or a dimension where there's an ender dragon boss event, the sight distance in the distance fog (not water, lava, powder snow fog) is half of the rendering distance, and the maximum sight distance is 96 blocks. The shape becomes a sphere.
=== Removed ===
==== Void fog ====
{{outdated|edition=java|section=1}}
[[File:Void fog.png|400px|right]]
In prior versions of ''Java Edition'' (specifically [[Java Edition Beta 1.8 Pre-release|Beta 1.8 Pre-release]] through [[14w34b]] inclusive, up to its removal in [[14w34c]]), a thick black fog was introduced. As the player descended below Y=26, this fog would start to appear. As the player traveled deeper, the fog at the edge of the render distance would become closer until the player reached the first layers of [[bedrock]], where visibility was reduced to just a few blocks, beyond which was complete darkness. The gray void particles started appearing below Y=7, as well as in the void.
The existence of this fog depended on a lack of sky lighting. If vent holes were opened up to allow skylight to enter an otherwise secluded underground space, void fog would no longer be present, so long as the player kept near this skylight source.
Void fog was removed late into 1.8's development for performance reasons and general community distaste.[{{tweet|TheMogMiner|501766046681153536|Removed void fog today. Now we don't need to tick air blocks (seriously, WTH?), and honestly, who actually *liked* the void fog?|August 19, 2014}}]

== ''Bedrock Edition'' ==
{{IN|bedrock}}, fogs have six types used in six different circumstances:
* air: When the camera is in air
* water: When the camera is in water
* lava: When the camera is in lava, and the player has no [[Fire Resistance]]
* lava resistance: When the camera is in lava, and the player has Fire Resistance
* weather: When in air and it's raining
* powder snow: When the camera is in powder snow
In a fog setting file in a resource pack, one or more of above types can be specified. Active fog settings are determined from three aspects:
* Custom fog stack (from {{cmd|fog}} command)
* Fog settings for the current biome
* Default fog setting
Whenever the game needs to get the current fog, it checks the fog settings from these three aspects from the top (the newest fog setting in the fog stack from the command) to the bottom (default fog setting) in order, until it finds a fog definition for the current fog type. If it finds no matching setting, the game uses the hardcoded default setting of the Bedrock Engine.
In other words, this is equivalent to that all fog settings from the three aspects are applied one by one from the bottom (default fog setting) to the top (the newest fog setting in the fog stack from the command) in order. The fogs in a fog setting applied later overrides that of earlier fog settings. Each fog type works independently. Hardcoded default setting of the game engine is applied before settings from these three aspects.

|{{HistoryLine||v0.1.0|Added distance, water, and lava fog.

|Due to changes made to chunk rendering in this version, fog is now visible only on chunks that are far enough away from the player.

|{{HistoryLine||v0.9.0|dev=build 1|Distance fog now covers % of the render distance, with being the player's render distance in blocks.
|This version also added a minimum start distance of 72 blocks to distance fog, resulting in glitchy behavior if the player sets their render distance to 4 chunks.|In particular, setting the render distance to 4 chunks would cause water to become colored with the fog color, making it indistinguishable from the fog, and cause mobs to lose their textures and become colored with the fog color as well.}}
|{{HistoryLine|||dev=build 2|The glitchy low render distance fog behavior in the previous build was fixed by adding a minimum distance of 4 blocks between the render distance limit and the start of the fog area, preventing render distance values lower than the minimum available through the settings from being used.}}

|Distance fog now becomes fully opaque at 20% of the distance between the player and the render distance limit.
|The 72 block minimum start distance for distance fog has been removed.
|Water fog now becomes fully opaque 8 blocks away from the camera.
|Lava fog now becomes fully opaque 1 block away from the camera.
|[[Sky]] coloring is now visible through water and lava fog if the "Beautiful skies" toggle is enabled.}}
