*The first mapgen*

In the very first known version of Minetest-c55, there was just flat terrain made out of grass blocks with [stone](https://wiki.luanti.org/Stone "Stone") pyramids on top. There were a few holes. There were no other blocks or caves. The terrain was always the same.

The terrain was no longer flat and the pyramids are gone. The terrain generation was horrible, but at least terrain could be generated. It consisted of grass blocks and stone at surface. Very simple squareish caves could be found below the surface. The terrain was still not random.

[Sand](https://wiki.luanti.org/Sand "Sand") has been added and formed sand beaches. A simple mud flow algorithm smoothens out dirt / dirt with grass hills. The cave generation has seen notable improvements and [iron ore](https://wiki.luanti.org/Iron_Ore "Iron Ore") has been added as well.

Historic mapgen version 5 in Minetest-c55 0.3.0

In the 0.3 versions, this map generator hat predefined biomes like the current v6 map generator. In Minetest-c55 0.4, it was removed, but has been revived later (→[#v5](#v5)).

This version introduces jungles, deserts and rare gravel fields.

Mapgen v6 in Minetest 0.4.13-dev

The mapgen “v6” (also known as “mgv6”) is the direct continuation of [version 6](#Version_6) (before support for multiple mapgens has been added) and has pretty much the same features. In Minetest 0.4.13, support for snow biomes and ice sheets has been introduced to v6. This mapgen it is still officially supported in Minetest, it will not be removed anytime soon and improvements and bugfixes are still applied from time to time.

singlenode mapgen in Minetest 0.4.13

This mapgen was introduced in Minetest 0.4.6 by [celeron55](https://wiki.luanti.org/Celeron55 "Celeron55"). It creates a world with only [Air](https://wiki.luanti.org/Air "Air") (can be changed with configuration) and is intended to be used by [mods](https://wiki.luanti.org/Mods "Mods") and [games](https://wiki.luanti.org/Games "Games") for making custom map generators, so they can start completely from scratch. The name “singlenode” means that it generates a _single_ type of _node_ everywhere, [Air](https://wiki.luanti.org/Air "Air") by default.

This map generator has been hidden from the map generator selection screen for a couple of versions up to 0.4.16, in which it has been re-enabled again.

### indev

This mapgen was introduced in Minetest 0.4.6 by proller and contained many experimental features. It is based on v6. Major new features included floating islands at Y=500 and above, rare huge caves, and a more extreme terrain near the [world boundaries](https://wiki.luanti.org/World_boundaries "World boundaries") in form of larger biomes, higher mountains and deeper oceans. It has been removed in version 0.4.10 because it was considered to be of low quality.

Also called “mgv7”. It was introduced in Minetest 0.4.7 by kwolekr, in which the map generator was still unusable. This map generator uses a combination of 2D and 3D Perlin noise. It is notable for its large rivers at Sea level. Caves in v7 are also very different than in v6, they are generally much larger.

This mapgen has a long history of development and has seen countless improvements over the Minetest versions.

“mengersponge” mode of the math mapgen in Minetst 0.4.9 with lighting bugs

The mapgen “math” was introduced in Minetest 0.4.8 by proller. This was really a collection of 3 different map generators based on simple maths. It was capable of creating Menger sponges, mandelboxes and spheres. Mods could adds biomes with Minetest's biome API, but this was never used in Minetest Game, so only stone worlds were created by default.

This map generator has been removed in Minetest 0.4.10 when proller left the project because it was considered to be of very low quality and had many obvious lighting problems ([\[1\]](https://forum.minetest.net/viewtopic.php?f=3&t=7256#p148920)).

[![](/images/mapgen/Mapgen_v5.jpg)](/images/mapgen/Mapgen_v5.jpg)

Modernized mapgen v5 in Minetest 0.4.13-dev

Also called “mgv5”. This mapgen is a revival of the [historic map generator version 5](#Version_5) from Minetest-c55 0.3. In Minetest 0.4.11, this historic map generator has been revived by paramat because of its iconic terrain shape.

But this mapgen is not identical to the historic version 5. The terrain shape is _nearly_ identical to the historic version. The main difference is that the modernized v5 map generator has mod-defined biome support (like v7), rather than predefined biomes. It also shares many other features with v7 which are not related to the terrain, for example desert and sandstone dungeons. Some features which have been added to v7 were often also added to v5.

One of many possible terrains by the fractal mapgen in Minetest 0.4.13-dev

Introduced in Minetest 0.4.13 by paramat. It creates worlds based on fractals, specifically those based on 3D and 4D Mandelbrot and Julia sets, including a mandelbulb. As of version 0.4.15, there are 18 variants which this mapgen supports. This mapgen has a similar intention like the old math mapgen, but it has a very different feature set compared to math.

valleys mapgen in Minetest 0.4.13-dev

Introduced in Minetest 0.4.14 by Duane Robertson. It is notable for its “valley”-like shapes and its flowing rivers. These rivers are very different than in v7: They flow downhill rather than being flat at ocean level.

In Minetest Game, these rivers are made out of [River Water](https://wiki.luanti.org/River_Water "River Water"), a liquid which has been introduced in the same version for the rivers. It has been introduced because a liquid with a reduced flowing range was needed, as normal [Water](https://wiki.luanti.org/Water "Water") would easily flow over.

carpathian mapgen in Minetest 0.5.0-dev-8221d3bc

Introduced in the developer version on 6th July 2017 by vlapsley. It has been first showcased [in the forums](https://forum.minetest.net/viewtopic.php?f=9&t=17174). About 1.5 years later, it was finally released in a stable Minetest release: Minetest 5.0.0. This mapgen is notable for its complex mountains (multiple variants: terraced, stepped, very big, ridged) and hills. Vast flat plains, mountains and oceans dominate the landscape. Fjords are also possible, but rare.
