Editable World Generation Mod FAQ
10 questions players actually ask, answered.
How do I create a world with this mod?
Click Create New World, then change the world type dropdown from Default to Custom. You'll then see an Edit rules button that opens the generation editor where you can adjust all your settings before world creation.
Can I edit world generation while playing?
Yes, the mod includes a real-time editing mode that lets you update generation rules as you explore. Changes apply to newly generated chunks, so you can walk into modified terrain without restarting.
How do I preview my custom rules before creating a world?
In the rules editor, click Generate Preview to see a spinning 3D landscape sample. This shows you how your current settings will generate terrain so you can adjust before committing to world creation.
Can I customize the Nether and End separately from the Overworld?
Yes, the mod provides separate rule sets for the Overworld, Nether, and End. You can adjust terrain, caves, biomes, and structures independently for each dimension.
How do I save and share my custom world generation settings?
Click Open Settings Folder in the editor to access your preset files. You can export your current rules as a file to back up or share with others, and import saved presets to load them into new worlds.
What world generation aspects can I customize?
You can adjust terrain height and shape, cave size and frequency, biome distribution, surface vegetation, ore deposit rates, structure spacing, and even replace or remove specific block types during generation.
Do I need to use the preview before creating my world?
No, the preview is optional—it's just a helpful tool to test your rules on a random seed before committing. You can skip it and create your world directly if you prefer.
Can I make a completely flat world with custom rules?
Yes, you can adjust terrain height settings to create flat worlds. The mod lets you control surface elevation precisely, so you can flatten terrain while keeping other features like caves, biomes, or structures active.
What happens if I change rules in the middle of playing?
Only newly generated chunks will use your updated rules. Chunks you've already explored will keep their original generation, so you'll see a transition between old and new terrain as you walk outward.
Can I remove specific ores or blocks from generating?
Yes, the mod includes block replacement and removal tools in the generation editor. You can disable specific ore types, decorative blocks, or other elements from spawning during world generation.
