Minecraft Snapshot 21w17a

Changes to the Caves & Cliffs Preview

Download the updated datapack here.

• Large Ore Veins have been tweaked
• Added noodle caves – thinner, squigglier, and more claustrophobic variant of spaghetti caves

Large Ore Veins

• Ore veins are now slightly rarer and slightly smaller (but they are still large!)
• The ores in the vein are clumpier and less evenly distributed
• If you are lucky you may find a raw ore block in the vein
