¶ 7D2D: KingGen World Map Generator
¶ Overview
KingGen is a random world generator for the survival horror crafting game 7 Days to Die. It is an alternative to the game's built-in random world generation (RWG) and Nitrogen World Map Generator. Using KingGen, players can create customizable random worlds for their 7D2D server (which you can host with indifferent broccoli). The tool was released March 31, 2021 by 7D2D community member KingSlayerGM.
¶ Installation
Download and install KingGen on your local computer (client-side).
¶ Benefits
KingGen offers numerous benefits over vanilla world generation:
- Beautiful generated worlds, with natural landscapes and large cities
- Fast world generation, including on older machines
- Random biome placement for limited repetition
- Smart biome distribution (e.g. deserts and snow never touch)
- Noise-based, rather than stamp-based. This means no two lakes, mountains, or other features look identical
- Supports advanced customization
¶ Performance
KingGen has fast performance. Below is a summary of execution time and RAM usage for various map sizes:
| Size of world | Execution time | RAM usage |
| 4K | 30 seconds | 500 MB |
| 8K | 2 minutes | 1.5 GB |
| 12K | 5 minutes | 3 GB |
| 16K | 10 minutes | 6 GB |

¶ Generating a Map
Run the program, then follow the steps below:
1. Set your map name (E.g. KingGenMap).
2. Set your map seed.
3. Set your map size. The default values are 4k, 8k, and 16k.
4. Configure the different heightmaps and other advanced settings.
5. Press the Generate World button.
¶ Importing your new World
To upload your newly generated map to your server, you'll need access to your server's file system.
1. Create a "GeneratedWorlds" folder on this path: /.local/share/7DaysToDie/GeneratedWorlds
2. Upload your generated map folder (E.g. MyKingGenMap) to the server's GeneratedWorlds folder. It will look like this: /.local/share/7DaysToDie/GeneratedWorlds/MyKingGenMap
3. Set your GameWorld value to the name of your uploaded folder (E.g. GameWorld=MyKingGenMap). This is located in your serverconfig.xml file. If you have an Indifferent Broccoli 7 Days to Die server, you can set this in the Game Server Settings of your web control panel.
4. Restart your server.
