Minecraft Snapshot 21w17a

A Minecraft Java Snapshot

A delicious snapshot appears! This snapshot introduces some tweaks to the raw ore textures, a few copper changes, and the introduction of noodle caves in the Caves & Cliffs Preview datapack.

If you have any feedback, a penne for your thoughts…

Changes in 21w17a

  • Small Dripleaves can now also be placed on Moss Blocks
  • Copper Ore drops 2-3 raw Copper when mined, or more when using a tool enchanted with Fortune
  • Copper Blocks are now crafted from 9 Copper Ingots
  • Tweaked the texture of raw Metal blocks

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
