1.20.1 Worldgen

File Location: Make sure to put it in: kubejs/data/Insert Name OF Mod Here/worldgen/configured_feature/identifier.json

This file needs to contain:

{
    "type": "minecraft:no_op",
    "config": {}
},

For Example: if we wanted to remove all minecraft ores, we would create ore.json in:

kubejs/data/minecraft/worldgen/configured_feature/ore.json and insert the above code snippet.

Note: the identifier ore removes all minecraft ores

This removes all Minecraft ores.

If we wanted to remove a specific ore it is a similar process.

See https:

To remove iron we create a file at this path kubejs/data/minecraft/worldgen/configured_feature/ called ore_iron.json

This JSON file contains the code shown above.

I recommend you check out https:

In order to change a vanilla worldgen feature name the file identifier-of-feature.json

Using a preset you could probably even add your own custom geode.
