=== order ===
'''Type''': [[Types/Order]]
 
Specifies the ordering in the [[map generator]] gui.
 
== Optional properties ==
 
=== default ===
'''Type''': [[Types/bool]]
 
'''Default''': true
 
Whether this is the default preset. If set to true, this preset may not have any other properties besides this and order.
 
If no MapGenPreset has <code>default = true</code>, the preset selector will have a blank preset label, having default settings, which goes away when another preset is selected.
 
=== basic_settings ===
'''Type''': [[Types/table]]
 
This is a table with the below key/value pairs. All key/value pairs are optional. If not set they will just use the default values.
 
* terrain_segmentation - [[Types/MapGenSize]]
:: This is the inverse of "water scale" in the map generator GUI. So a water scale that shows as 50% in the GUI is a value of <code>1/0.5 = 2</code> for <code>terrain_segmentation</code>.
* water - [[Types/MapGenSize]]
:: Shown as water coverage in the map generator GUI.
* default_enable_all_autoplace_controls - [[Types/bool]] - Default: true
:: Whether undefined autoplace_controls should fall back to the default controls or not.
* autoplace_controls - [[Types/table]]
:: Table of [[Data.raw#autoplace-control]] name keys mapped to table values. Each table can have the following fields:
::* frequency - [[Types/MapGenSize]]
::* size - [[Types/MapGenSize]]
::* richness - [[Types/MapGenSize]]
::Example:
::<syntaxhighlight lang="lua">autoplace_controls =
  {
    ["iron-ore"] = { richness = 2, size = 0.5, frequency=2},
    ["enemy-base"] = { size = 1},
    ["trees"] = { richness = 4}
  }</syntaxhighlight>
* autoplace_settings - [[Types/table]] of [https://lua-api.factorio.com/latest/Concepts.html#AutoplaceSettings AutoplaceSettings]
:: Each setting in this table maps the string type to the settings for that type. Valid types are "entity", "tile" and "decorative".
* property_expression_names - [[Types/table]]
:: Map of property name (e.g. "elevation") to name of [[Prototype/NamedNoiseExpression|noise expression]] that will provide it. Entries may be omitted. A notable usage is changing autoplace behavior of an entity based on the preset, which cannot be read from a noise expression.
* starting_points - [[Types/table]] of [[Types/Position]]
:: Array of the positions of the starting areas.
* seed - [[Types/uint32]]
:: Read by the game, but not used or set in the GUI.
* width - [[Types/uint32]]
:: Amount of tiles from left to right. Silently limited to 2,000,000, +/- 1 million tiles from the center.
* height - [[Types/uint32]]
:: Amount of tiles from top to bottom. Silently limited to 2,000,000, +/- 1 million tiles from the center.
* starting_area - [[Types/MapGenSize]]
:: Size of the starting area. The starting area only effects enemy placement, and has no effect on resources.
* peaceful_mode - [[Types/bool]]
* cliff_settings - [https://lua-api.factorio.com/latest/Concepts.html#CliffPlacementSettings CliffPlacementSettings]
 
=== advanced_settings ===
'''Type''': [[Types/table]]
 
This is a table with the below key/value pairs. All key/value pairs are optional, if not set they will just use the existing values.
* pollution - [[Types/table]]
