1.18 Experimental Snapshot 1

1.18 Experimental Snapshot 1 (known as 1_18_experimental-snapshot-1 in the launcher) is the first experimental snapshot for Java Edition 1.18, released on July 13, 2021,[1] which introduces new terrain generation and enables features from the preview data pack.

Additions

World generation

Caves
  • Completely overhauled.
  • Now stretch down to Y=-59.
  • The cavern now generates in 2 layers of different stone bases depending on the depth.
    • Cavern layer above Y=0 is made up of regular stone.
    • Stone transitions to deepslate from Y=0 to Y=-7.
    • Deepslate now completely replaces stone from Y=-8 to bedrock.
      • Certain types of ores and structures still generate in the deepslate layer, as well as tuff.
      • Dirt, diorite, granite and andesite do not generate in this layer.
  • Contain aquifers, bodies of water with different heights, independent of sea level (Y=63).
    • Aquifers below Y=0 sometimes generate with lava instead of water.[2]
  • Improved old caves, adding more variation.[3]
  • New noise caves, coming in 3 forms, cheese, spaghetti and noodle.
    • The original caves still exist with their generation slightly tweaked to better blend in with noise caves.
    • Cheese caves have large stone towers stretching from the bottom of the cave to the top.
      • Very large, often large enough to fly with elytra.
      • Abundant with springs, aquifers and ores.
    • Spaghetti caves are long, thin caves that have small aquifers and are more similar to original caves.
    • Noodle caves are thinner, squigglier and more claustrophobic variants of spaghetti caves.
Mountains
Ore veins

Technical

Debug screen
  • Added two new lines: Multinoise and Terrain.
    • Only appear if the dimension where the player is uses the multi-noise biome source type.
    • Multinoise lists the parameters used at the player's position in order to place a biome. C is continentalness, E is erosion, T is temperature, H is humidity and W is weirdness.
    • Terrain lists values related to terrain generation.[more information needed]

Changes

Blocks

Sculk Sensor
  • Have been re-added to the Creative Mode inventory.
Snow Block
  • Plants can now be placed on snow blocks.

Items

Bundle
  • Have been re-added to the Creative Mode inventory.
  • Can once again be crafted.

Mobs

Axolotls
Goat
General
  • Hostile mobs only spawn in areas where the light level is 0.
    • This change only affects block-light and not sky-light.[4]

World generation

Overworld
  • Now uses the multi-noise biome source type.
Lush Caves and Dripstone Caves
  • Now generate naturally underground and inside hills or mountains.
Deep Warm Ocean
  • Now generates naturally.
Swamp
  • Does not generate correctly. This is fixed in 1.18 experimental snapshot 2.[5]
Sub-biomes

The new ore generation for 1.18 Experimental Snapshot 1.

Ore distribution
  • Changed ore generation of all ores making them have a spread value like lapis lazuli ore. Some still retain a linear generation alongside a spread generation.
  • Coal ore, emerald ore, and copper ore no longer generate below Y=0.
    • Copper ore generates between Y=0 and Y=96 and like all other ores, uses spread. It peaks at Y=48.
    • Emerald ore generates above Y=32 as a spread, peaking at Y=256 and decreasing in quantity as the altitude decreases.
    • Coal ore attempts to generate twice: once, evenly between an altitude of Y=136 and Y=256; and as a spread, peaking at an altitude of Y=96 and generating between an altitude of Y=0 and Y=192.
  • Other ores also generate differently.
    • Iron ore attempts to generate three times: once as a spread peaking at an altitude of Y=256, generating above Y=128; another as a spread peaking at Y=16 and generating with a minimum height of Y=-24 and a maximum height of Y=57, and a smaller one spreading evenly between the altitudes of Y=-64 and Y=-32.
    • Gold ore generates between the altitudes of Y=-64 and Y=32, peaking at Y=-16. The extra gold that generates in the badlands biome was left untouched.
    • Lapis lazuli ore attempts to generate twice: once, as a spread between the altitudes of Y=32 and Y=-32, peaking at an altitude of 0; and evenly between the altitudes of Y=64 and Y=-64, generating buried like ancient debris.
    • Redstone ore attempts to generate twice: once, evenly between an altitude of Y=15 and Y=-64; and as a spread, peaking at an altitude of -64 and generating below an altitude of Y=-32.
    • Diamond ore now generate as a spread, generating below Y=16 and peaking at altitudes near Y=-64.
General
  • Terrain generation is now independent from biomes, with biomes adapting to whatever terrain they happen to generate throughout.[6]
    • This allows for natural variation in the terrain of any individual biome, both in terms of shape and elevation.
      • For example, forests and deserts could form up on a hill without needing a special biome just for that purpose.
    • This additionally allows for smoother transitions between biomes.
  • Terrain is now smoother and more extreme.

General

Height limit
  • Has been increased to 384 blocks, expanding 64 blocks up and 64 blocks down, with 320 being the limit upward and -64 being the limit downward.

    • The spawning rates are similar to 1.17's spawning rate at y=64.

World generation

Aquifers
  • Aquifers can go deeper and are more likely to connect with cave systems further down.

  • Reduced the chance of incorrect surface placement.
  • Reduced the chance of river biome generating in dry mountain gorges.

Fixes

  • Fixed goats not spawning in the new mountain biomes.
  • Fixed an issue where players in multiplayer can face far more or far fewer enemies than intended, particularly when other players are flying.
  • MC-30560 was fixed by this version, although it will not be marked as such due to the bug tracker not handling experimental snapshots.
