Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

The diamond edition of Larger Ore Veins changes the generation of diamond ore. The size of ore blobs has been greatly increased, but have also been made less frequent to balance it out.

Notice

This is a world generation datapack. World generation data packs work best when added to your world during the world creation phase. You can still add them to your world after generating it, you just need to generate new chunks to see the effects.

Modifying this pack

Make sure you download the data pack version of this project.

To modify the size of the ores, go to data/minecraft/worldgen/configured_feature and change the size value in the desired JSON files (The maximum size is 64).

To modify the rarity of the ores, go to data/minecraft/worldgen/placed_feature and edit the count values in the desired JSON files.
