Use Custom World Generators Without Crashes

Why Custom Generators Fail

Complex custom world generation data packs often fail to load because they use water lakes, snow features, or other worldgen elements in ways the vanilla game engine doesn't fully support. These incompatibilities cause crashes before your world ever generates. Worldgen Feature Fix Mod rewrites how the game reads these feature definitions, allowing custom generators to run safely.

Getting Your Custom Generator Working

1. Place your custom data pack in the datapacks folder

2. Install Worldgen Feature Fix Mod in your mods folder

3. Create a new world and select your data pack

4.

5. Verify terrain generation by exploring; custom features should appear without crashes

The mod doesn't modify your pack's behavior or output. It only fixes the underlying chunk data parsing that causes crashes. Your custom world generator will produce terrain exactly as designed, but reliably. This is essential for complex modpacks that layer multiple custom generation features together.
