OreReGen: The Vanilla Custom Ore Generation Data Pack

Do you think Vanilla Minecraft Ore Generation is boring? Every single ore, in the same, shapeless blob, identical in every biome?
This pack solves that problem.

This data pack removes the ore in the world, and regenerates it in shaped, biome specific veins. It can be run with a new world, or added to an existing one (if added to an existing one, it will remove all existing ore, and generate new ore).

Coal can be found in large flat sheets.
Iron generates in long thick veins, partially composed of granite.
Redstone always generates in long vertical veins, more commonly found in deserts along with red sand.
Diamond generates rarely, within deep veins of obsidian, magma, and lava.
Gold tends to generate in mostly diffuse clouds, more common in taigas, but never found in swamps
Lapis generates in long, thin veins of dead coral.
Emeralds generate in wet veins of cobblestone and mossy cobblestone found in all non-desert/badlands biomes.

Different biome types have varied sizes, shapes, and generation rates, and generation is now scaled to biome height, meaning ores will be more common higher up in taller biomes.

The shaped veins should generate at a rate slightly lower than vanilla. If you´re strip mining a chunk you will see less ore, however the longer, thicker veins will more often intersect with caves.

Also features built in support for Quarks mod- see the download mirror for the Addon pack

The configs are customizable, however at the moment it requires editting the datapack code (check ore and layer files in the generator folder) but will require some familiarity with DataPack command function (open the pack, and look in the generators folder).
