Shared features

These map generator features are shared by multiple map generators. All of these are enabled by default.

Name	Blocks	Supported mapgens	Setting	Description	Images
Cobblestone dungeon	Cobblestone, Mossy Cobblestone, Cobblestone Stair	v5, v6, v7, valleys, flat, fractal	`mg_flags=dungeons`	Dungeons are hollow underground structures made of a mixture of cobblestone and mossy cobblestone. Many pathways and cobblestone stairs connect a complex system of rooms.	Cobblestone dungeon, as of 0.4.7
Desert dungeon	Desert Stone, Sandstone Brick	v5, v7, valleys, flat, fractal	`mg_flags=dungeons`	Desert dungeons are similar to cobblestone dungeons, but they have larger rooms and longer stairways. They are either made out of desert stone or sandstone brick. Desert dungeons made out of desert stone appear inside desert stone and dungeons made out of sandstone bricks appear inside sandstone. In Minetest Game, desert dungeons can thus be found in deserts and sandstone deserts.	Desert dungeon with desert stone, as of 0.4.13 Desert dungeon with sandstone brick, as of 0.4.13

This mapgen has support for lakes and hills which are disabled by default.

Name	Setting	Description	Images
Hills	`mgflat_spflags=hills`	Increases the terrain height at some points to form hills. These hills become quite big sometimes.	Hill in the flat mapgen
Lakes	`mgflat_spflags=lakes`	Lowers the terrain at some points to form lakes. These lakes can become quite large sometimes.	Small lakes in the flat mapgen

Name	Setting	Description	Default?	Images
Mountains	`mgv7_spflags=mountains`	Yes	Enables mountains.
Ridges	`mgv7_spflags=ridges`	Yes	Enables rivers which aggressively cut through the terrain and create canyon-like structures. Since these rivers can make the terrain quite difficult to navigate, it may make sense to disable them.
Floatlands	`mgv7_spflags=floatlands`	No	With this setting, large chunks of land will be created in the sky at a height at Y=1280 or above. The terrain is a bit different than on the surface, but the biomes are more or less the same. This setting is experimental and subject to change.	Floatlands in 0.4.15
