Custom Default World Preset

This lightweight Fabric mod provides the ability to configure the default world preset in Minecraft. Modpack developers can set custom world generation settings by default without requiring players to manually select parameters when creating a new world.

To configure, you need to edit the default_world_preset.txt file in the configuration folder. This file should contain the identifier of the desired preset. The minecraft: prefix can be omitted. The configuration is read each time the function is used, so changes will take effect after reopening the world creation screen.

The mod also changes default settings on dedicated servers. For proper operation, you need to ensure that the selected preset is loaded in the initial datapacks. Most mods that add global datapacks are compatible with this feature.
