While the Caves and Cliffs Update has been split in two, that certainly hasn’t stopped Mojang from continuously pushing snapshots out.

We have another snapshot today with more cave themed changes to them. Check them out below.

New Features in 21w16a

  • Azalea and Flowering Azalea can now be bonemealed to get an Azalea Trees
  • Added dripstone growth

Dripstone growth

  • If a stalactite is hanging from a dripstone block with a water source above, it will slowly grow both the stalactite from above and a stalagmite from below
  • Growth speed is random but very slow, a single growth step can take several minecraft days
  • A stalactite will only grow up to 7 blocks long
  • A stalactite will only cause stalagmite growth if the floor or stalagmite below is within 10 blocks
  • If the stalactite tip is inside water it won’t drip, and therefore won’t trigger any growth
  • If the stalagmite tip is inside water it won’t receive drops, and therefore won’t be grown by a dripping stalactite. Same thing if there is any fluid between the two tips
  • A stalagmite or stalactite will never grow into a fluid

Changes in 21w16a

  • Tweaked the texture of raw ores and raw ore blocks

My Thoughts

It’s cool to see the stalagmites get some fine-tuning. I think they add to the immersion in caves, and I’m excited to see them finalized once the update drops.

Ore veins are also a great rare spawn to add to the game. Finding something like that after hours of mining would be a great little surprise!

Wrapping Up

The first half of the Caves and Cliffs Update will be here before you know it, but until then, at least we have a constant flow of snapshots to keep us satiated.
