OK we have a new experimental snapshot for you with more terrain generation and biome tweaks. Try it out (ideally in survival) and give us feedback!

This update can also be found on minecraft.net. See also snapshot 1 and snapshot 2 and snapshot 3.

Changes in experimental snapshot 4 compared to snapshot 3

  • Temple tweaks: Desert temples tend to be partially buried, and Jungle temples and Desert temples no longer generate on water.
  • Badlands and deserts are larger and less likely to show up as ugly microbiome splotches. Terracotta bands go higher. Wooded badlands grass and trees start higher.
  • Made biome placement a bit smoother and less noisy (again). This should result in fewer microbiomes (again). Tweaked biome placement in general to reduce the risk of harsh collisions.
  • Removed surface freezing for hot biomes, and raised the altitude at which snow layers are placed. This should result in fewer weird things like jungle trees with snow on top.
  • Made snowy slopes less dirty. Again. For real this time.
  • Made extreme hills terrain less unextreme. And fiddled with the placement of shattered terrain and extreme hills in general, to make it fit in with the terrain better.
  • Reduced the likelihood of rivers being cut off and turning into steep dry river gorges in mountainous terrain. Instead rivers will tend to either carve a fjord through the mountain range, or raise the terrain to form a saddle valley between the peaks. This should make the terrain friendlier for both walking and boating. I think it also makes rivers a bit wider in general.
  • Reduced the number of diorite/andesite/granite blobs on the surface. This should reduce the spray-paint look of stone shores and such.
  • Stone shores sometimes generate layers (strips) of gravel, diorite, andesite, or granite. Stony peaks sometimes generate layers of gravel, calcite, andesite, or granite. No more need to destroy geodes to get calcite :)
  • More iron! You'll still mostly have to go caving or mountain climbing to find it. But you'll find more iron when you do!
  • Swampier swamps. Tweaked swamp placement a bit, just to keep them happy. They are less likely to extend far out from the coastline now, and rivers in swamps tend to be shallower.
  • Bigger copper blobs in dripstone caves. Go to that biome if you want more copper! Either that or find a large copper vein.

NOTE: These snapshots are experimental! Some features may be significantly changed or even removed if needed to improve performance.

Known issues

  • Low performance (we are working on performance optimization for the normal snapshots coming later)
  • Nether terrain is still messed up
  • End pillars still don't generate (however they do generate when you respawn the dragon...)

How do I get experimental snapshot 4?

Check this visual overview

.

Installation

  • Download this zip file
  • Unpack the folder into your "versions" folder of your local Minecraft application data folder (see below if you are confused)
  • Create a new launch configuration in the launcher and select "pending 1.18_experimental-snapshot-4"
  • Start the game and the remaining files will be downloaded
  • Play in a new world! Note: This version is not compatible with other snapshots.

Finding the Minecraft application data folder

  • Windows: Press Win+R and type %appdata%\.minecraft and press Ok
  • Mac OS X: In Finder, in the Go menu, select "Go to Folder" and enter ~/Library/Application Support/minecraft
  • Linux: ~/.minecraft or /home//.minecraft/

How do I give feedback?

Use this reddit post or the feedback site.

We are mostly interested in feedback about the new world generation overall, and what it is like to play in it. We are also looking for feedback on the updated mob spawning.

New feature requests are not so useful at this point, since the scope of the Caves & Cliffs update is already large enough and we want to focus on finishing the features that we've already announced.

Note that we don’t use the bug tracker for experimental snapshots. If you find any new important bugs you can post them here.

Other questions

What about the previous Caves & Cliffs preview datapack? Can I open old worlds in this experimental snapshot? What about Bedrock? When will these features show up in normal snapshots?

These questions are answered in the original post for the first experimental snapshot

I think it would be a good idea to generate rivers at a higher level in the mountains biome and create waterfalls whenever the mountains biome end.

This is a huge change to the way we do terrain generation that I don't believe we can feasibly do this update.
