Larger Ore Veins: Nether
I don't know my version or loader
Larger Ore Veins: Nether Edition increases the size of nether gold ore and quartz ore veins while reducing their frequency. It also slightly increases the generation of ancient debris to make it easier to obtain, but not too easy.
Notice
This is a world generation data pack. 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, but you will 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)
