A19e NitroGen - a Random World Generator for 7DTD


This is a random world generator. It will create customizable random worlds for 7DtD. Configure your own personal world.

Damocles created NitroGen, a random world generation tool for 7 Days To Die.

This tool allows users to customize their procedurally created worlds while also assisting in the generation of large worlds!

It is an alternative to standard RWG generation with seeds. Note, this requires Java.

For an 8K map, world generation will typically take about 4 to 5 minutes.

Note: there is also one another alternative to Nitrogen: KingGen.


-type of landscape (currently included are Forests, Alpine Mountains, Canyon Desert, Rocky Hills)

-the number and size of cities and towns

-the general number of POIs and smaller settlements (Farms, trailerparks, old western towns, etc)

-4k, 8k, 16k (experimental) or custom dimension maps

-the player start positions (far away, close to towns or random)

-the number and position of traders (close to cities and towns, or far in the countryside)

-even import your selfmade hightmap (play on a realworld terrain or a cat picture)

-spawn together in Multiplayer, and spawn near a town if you want

-the number of traders

-[dedicated server, Ravenhearst, Darkness Falls (see bottom of the post)]

How to Setup NitroGen?

The first step is to download and install NitroGen on your local computer. Note, you need Java.

See the following instruction.


for Alpha 19:

NitroGen v0.501 A19 (experimental) A19 experimental version

for Alpha 18:

NitroGen v0474

NitroGen v0.481 Experimental (new highway feature and ability to generate several maps at once)

Performance: After you finished generating and installing the map, and want to play,

close NitroGen, as it reserves a substantial amount of memory for the generation.

World generation

Hit 'GENERATE WORLD' to create a default 8K map.

The world data will be saved to a folder (map name) inside the output folder.

You will have to copy the created world-files folder to your 'GeneratedWorlds' Directory for 7 DaysToDie

It should be somewhat like this: C:\Users--MyUserName--\AppData\Roaming\7DaysToDie\GeneratedWorlds

Then you can start a new world from within the game (the generated world-name will show up

in the selection when starting a new world)

Hint: close the Explorer window of the GeneratedWorlds folder after copying the world over, as A18 likes

to throw an access violation when having an active explorer window for the world-files.

Version v0.501

-highways added, those are performance hungry, so test first, you can use single or double land highways

-option to generate batches of maps

-deactivated 'POI placement limits', implementation was buggy

-can spawn traders inside cities (might cause nearby POIs to have indestructable blocks)

Current working directory: C:\Users--MyUserName--\nitrogen\NitroGen_WorldGenerator_v0501\NitroGen_WorldGenerator

(please check if this is valid)
