1.18.2 / (Addon) Ore Hints and Spawning / Ore Vein Tweaks
Making hint rocks also includes the mineral veins themselves, so why not make them better? Some of the veins were too small and too rare, so sizes, rarities, and some shapes changed!
Coal veins are now much larger horizontal discs with fewer inclusions. Most other mineral veins are more common and doubled in radius. Y-level restrictions are the same.
Ore Veins on the Brink
Exploring the depths and heights of the world may be more rewarding! More veins below y-level 0 now exist for all metamorphic and igneous intrusive ores: metal, mineral, and diamonds/emeralds. These veins may be larger, denser, and purer.
In the mountains, there are small, dense iron, copper and sulfur veins.
