This article shows the various special features which [[Map generator|map generators]] have and explains how to use them.

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

| Dungeons are [[Air|hollow]] underground structures made of a mixture of [[cobblestone]] and [[Mossy Cobblestone|mossy cobblestone]]. Many pathways and [[Stair|cobblestone stairs]] connect a complex system of rooms.

−
| Yes
 
−
| Desert dungeons are similar to cobblestone dungeons, but they have larger rooms and longer stairways. They are either made out of [[Desert Stone|desert stone]] or [[Sandstone Brick|sandstone brick]]. Desert dungeons made out of desert stone appear inside desert stone and dungeons made out of sandstone bricks appear inside [[sandstone]]. In [[Subgames/Minetest Game|Minetest Game]], desert dungeons can thus be found in deserts and sandstone deserts.

| '''Decorations'''
 
−
| ''(depends)''
 
−
| v5, v6, v7, valleys, flat, fractal
 
−
| <code>mg_flags=decorations</code>
 
−
| Yes
 
−
| Decorations are additional structures placed on top of the surface. Decorations can be small plants such as [[grass]], [[flower]]s, [[Cactus|cacti]], or they can even be entire trees or buildings. In all mapgens except v6, the decorations are defined by the mods. In v6, decorations are predefined. Disabling decorations in v6 does not affect [[trees]] and [[Jungle Grass|jungle grass]].

|-
 
−
| '''Caves'''
 
−
| [[Air]]
 
−
| v5, v6, v7, valleys, flat, fractal
 
−
| <code>mg_flags=caves</code>
 
−
| Yes
 
−
| Caves are [[air]] pockets found underground at any [[Coordinates|height]]. Caves can be very small hollow places or can be very complex interconnected tunnel systems. Cave entrances can commonly found on the surface. The cave style greatly varies between the different map generators.
 
−
|-
 
−
| '''Underground lava lakes'''
 
−
| [[Lava]], [[Ores]], [[Air]]
 
−
| v5, v6, v7, valleys, flat, fractal
 
−
| <code>mg_flags=caves</code>
 
−
| Yes
 
−
| These lakes are caverns flooded with [[Lava|lava]]. [[Ores]] are very common around these lakes (see screenshot). However, often these caverns are not linked to, and it is very difficult to reach them. Lava lakes are a subset of caves and only appear when caves are used. Lava appears at the [[Coordinates|height]] Y=-273 and below for all map generators except v6. In v6, lava can already be found at Y=-32 or lower.

−

−
| Yes
 
−
| Like lava lakes, these lakes are caverns flooded with [[water]] and can appear at any height. Lava lakes are a subset of caves and only appear when caves are used. They don't appear in v6.

| 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.

−
| 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.
