About Larger Ore Veins: Classic
From ModrinthIncreases the size of coal, iron, copper, and gold ore blobs and makes them less frequent
Join our discord to report bugs and make suggestions.
This simple datapack changes mining to make it more rewarding when you find coal, iron, copper, or gold. The size of the ore blobs has been greatly increased, but have also been made less frequent to balance it out.
Coal ore blobs have a chance of generating coal blocks
Iron ore blobs have a chance of generating raw iron blocks
Copper ore blobs have a chance of generating raw gold blocks
Gold ore blobs have a chance of generating raw gold blocks
Some ore deposits are so concentrated that you can find small blobs of raw iron or raw gold
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. (Note, some files currently use rarity_filter instead of count, this will be changed in an upcoming update)
