Minecraft:Far Lands (Java Edition)/After Beta 1.8
More actions
Template:Seealso Template:Exclusive
The Far Lands were a terrain bug that occurred in versions of Template:MC up to Beta 1.7.3. They were caused by errors in the math that governs terrain generation, resulting in abnormal structures resembling excessively stretched-out terrain.
The X/Z Far Lands were fixed in Beta 1.8 Pre-release, so they do not exist without modifications to Minecraft. In addition, most of the distance effects were fixed. The Y Far Lands (aka the Sky and Ground Far Lands) were overlooked, but were fixed in 1.13 with the world generation rewrite.
It is possible to force the X/Z Far Lands to generate in a Custom World when setting the Coordinate Scale to extreme high values.
Technical
The Far Lands were a terrain generation bug that occurred at ±12,550,824 along the X and Z-axes prior to Beta 1.8, as well as the Y-axis (technically) before Java 1.13.
The Far Lands generate because of an integer overflow error within Minecraft. The Minecraft:noise generator that draws Minecraft's height map increases by 171.103 for every block, causing an integer overflow at approximately ±12,550,824 (sometimes ±12,550,821.) Multiplying the aforementioned numbers results in the 32-bit signed integer max value, which when overflowed, results in an extreme noise seed.
Location
On the X and Z axis, the Far Lands and Farther Lands initiate as they did in Beta 1.7 and below (±12,550,824), with an identical chance of offset at positive positions. However, due to the new height limits and new world generation, they are actually 256 blocks tall, instead of 128. And the Far Lands look more rounded. There is a world border at the 32-bit integer limit (2,147,483,647), which crashes the game upon approaching (likely due to an integer overflow when casting the player's position to a 32-bit integer).
Any attempt to quit the game near the 32-bit integer limit also results in crashing.
On the Y-axis, the Far Lands initiate at around twice the former number, which is therefore ±25,101,648.
The Farther Lands also generate at ±2,008,131,840 on the Y-axis, however, they cannot be generated without lowering the selector noise period.
The location of the 64-bit variant of the Far Lands depends of the game version. In versions between Beta 1.8 and 1.6.4 inclusive, they start at 59 quadrillion blocks. In versions 1.7.2 through 1.13.2, they start at 53.9 quadrillion blocks due to a small change in the coordinate scale, that is not noticeable for 32-bit overflowing. The Far Lands in positive coordinates don't begin exactly after Template:Frac blocks due to the remainder of the overflow. The Far lands in negative coordinates have a remainder of 232, as a result, they begin exactly after Template:Frac blocks. In versions 1.14Template:Check version and later they start at 1.8 septillion blocks, due to a change in that version that takes the noise coordinate and divides it by 225.
Structure
The edge Far Lands and corner Far Lands, as well as their Farther variations, generate relatively identically to their pre-Beta 1.8 counterparts, but utilizing the entire height limit, causing them to generate all the way up to y=256 until they reach the sky Far Lands at y=+25,101,648 (and equivalently the ground Far Lands at y=-25,101,648). Since the 21w06a snapshot and until 1.18.1, however, The Far Lands are thinner and more geometrical, with a cross-section made of perpendicular lines and rectangles.
As of 1.18.2, they appear as a giant wall of stone with caves in them.
Far Lands
Sky Far Lands
The Far Lands generate at positive values of the Y-axis past y=25,101,648. Minecraft:Monoliths generate up to this point if the player can get them to generate.
Setting the Height Scale extremely high can generate the Far Lands in the sky up to the height limit.
This is possible in Vanilla.
Vertex Far Lands
When the Sky or Ground Far Lands meet with the vanilla Corner Far Lands, many interesting terrain features can be sighted. The content of these intersections appears to vary throughout worlds, with some being completely blank, some completely solid, and some generating like regular Far Lands material. In some cases, diagonal patterns with large absent chunks generate.<ref>Template:Ytl</ref>

Depth noise Far Lands
Like low/high and selector noise which respectively control the Far and Farther Lands, depth noise can be made to overflow at a given position. By default, it overflows at 42,949,672.96 blocks. Due to the Far Lands initiating before it, the overflow in depth noise is effectively impossible to see. However, if depth noise is made to overflow before tradition far lands, achievable by pushing the far lands farther out than this distance or moving the depth noise far lands closer, the effects can be seen immediately as it overflows, the terrain jumps up a few blocks. Terrain after this point is slightly more boring than before due to depth noise controlling subtle variation, which no longer exists after the overflow due to it almost always being at the max possible value. Every so often, very long "rifts" characteristic of depth noise far lands can be seen, which extend for extremely long. These rifts end once they hit the point twice the distance of the first overflow, and rifts as a whole past this point do not seem to be able to come into existence. Rifts have also only been noted on the positive X axis and are yet to be found on the Z axis.
The Fringe Lands
The Fringe Lands are a stage of terrain breakdown where the Far Lands begin to break down at extremely high distances. Unlike Bedrock Edition and pre-b1.8, in modern versions they do not generate with any skygrid artifacts without additional modification to the game's code. The X axis breaks down at about 8.6 quindecillion blocks, earlier than the Z axis at about 9.17 quindecillion blocks for a currently unknown reason, resulting in one 2D stripe of worldgen surrounding by an infinite ocean if X&Z noise scale is set high enough.
Corner Fringe Lands
The Corner Fringe Lands appear much earlier than the regular Fringe Lands, at around 40.5 septillion blocks on both axes.
Fringe Farther Lands
The Fringe Farther Lands appear between 2.5 duodecillion and 10 duodecillion blocks out. Also after the Z Fringe Farther Lands completely broke down, a skygrid can generate.
Vertex Fringe Lands
This type of fringe lands only appears if you set the noise multiplier of all three axis to 1 quadrillion. The vertex fringe lands degrade into skygrid at the much earlier coordinate of 100 quadrillion blocks, and this coordinate does indeed vary.
Effects
While completely unrelated to terrain, these effects occur coincidentally with Far Lands due to their shared extreme distances and are worth noting as a result.
Floating-point precision errors with entities and particles
Even in modern versions of Minecraft, the floating-point precision errors still exist, but only with translucent block rendering, natural snow generation and snowfall at extreme heights.
Darkness
Template:Main In vanilla Minecraft 1.14, the lighting system breaks beyond 225 (X/Z ±33,554,432)<ref>Template:Bug</ref> (though this distance is available only via editing source codes), however, it isn't like what would happen beyond X/Z=32,000,000 in older versions. Instead, everything abruptly becomes absolutely dark and ignores light sources. By pressing F3, it shows that the sky light level is 0, thus undead mobs do not burn when exposed to the sky. The chunks, however, are still solid and block physics still function. Night Vision can help to counteract the visual darkness; it is currently unknown whether the Minecraft:Conduit Power effect works or not.
Explanation
Template:Main The Far Lands happen for much the same reason as they used to. As 64-bit overflowing has not been patched, its breaking can be calculated by replacing 231 in calculations with 263. A table of useful values are as follows.
Vanilla
In Custom World Type worlds, by setting the coordinate scale very high it is possible to generate Far Lands-like formations in Vanilla Minecraft. The only form of recognizable farlands however is a form of selector noise failure resembling a wider form of the farther lands.

Trivia
In Super Smash Bros. Ultimate
In Minecraft:Super Smash Bros. Ultimate, the "Classic Mode" route for Steve and Alex is titled "Journey to the Far Lands", in which the player faces off against other Super Smash Bros. fighters, all resembling mobs that appear in Minecraft.
The End
The End was implemented after the Far Lands were removed, meaning that the End Far Lands never generated naturally.
