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[]
- Completely overhauled.
- Now stretch down to Y=-59.
- The cavern now generates in 2 layers of different stone bases depending on the depth.
- 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.
- 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.
- Come in 5 sub-biomes:
- Meadow
- A flat but elevated biome that looks like a flowery and colder plains, with an aqua grass color and dark blue water color.
- Generates in plateaus and the lowest layers of some mountains, usually near plains and other temperate biomes.
- Contains grass, tall grass, dandelions, azure bluets, cornflowers, blue orchids, poppies, daisies and alliums.
- Only rabbits and donkeys spawn in this biome.
- Grove
- Reminiscent of a snowy taiga with snow blocks instead of grass blocks.
- Generates in the slopes of a snowy mountain when next to forested biomes.
- Covered in snow, snow blocks, powder snow and is filled with spruce trees.
- Rabbits, wolves, foxes, sheep, pigs, chickens and cows spawn in this biome.
- Snowy Slopes
- Lofty Peaks
- Snowcapped Peaks
- One of the biomes that generate in the mountain peaks.
- Generates if the surrounding biomes are too cold for lofty peaks.
- Covered in snow, snow blocks, ice, and packed ice.
- Only goats spawn in this biome.
- Meadow
- Long and rare ore formations.
- Copper ore veins mixed with granite and raw copper block generate above Y=0.
- Iron ore veins mixed with tuff and raw iron block generate below Y=0.
Technical[]
- 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[]
- Have been re-added to the Creative Mode inventory.
- Plants can now be placed on snow blocks.
Items[]
- Have been re-added to the Creative Mode inventory.
- Can once again be crafted.
Mobs[]
- Now only spawn in lush caves.
- Now only spawn in the new mountain biomes.[more information needed]
- 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[]
- Now uses the multi-noise biome source type.
- Now generate naturally underground and inside hills or mountains.
- Azalea trees now generate above lush caves.
- Now generates naturally.
- Does not generate correctly. This is fixed in 1.18 experimental snapshot 2.[5]
- Sub-biomes
- Wooded hills, birch forest hills, tall birch hills, taiga hills, taiga mountains, gravelly mountains+, desert hills, desert lakes, savanna plateau, shattered savanna plateau, swamp hills, dark forest hills, ice spikes, snowy mountains, snowy taiga hills, snowy taiga mountains, modified jungle, jungle hills, bamboo jungle hills, jungle edge, modified jungle edge, giant tree taiga hills, giant spruce taiga hills, eroded badlands, badlands plateau, modified badlands plateau, modified wooded badlands plateau, and mushroom field shore biomes no longer generate naturally.
- Ice spikes, eroded badlands and savanna plateau were added back in 1.18 experimental snapshot 2.[5]
- Jungle edge was added back in 1.18 experimental snapshot 5.
- 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=72.
- 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]
- Terrain is now smoother and more extreme.
General[]
- 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.
- Removed the Large Biomes and Amplified world types.

Fixes[]
- MC-126009 could be considered fixed by this version.
Issues[]
This version is not supported on the bug tracker, and therefore issues affecting it will be resolved as "Invalid".[7]
Trivia[]
- This is the first time that the light level requirement for common hostile mob spawning has been changed for more than 10 years. The "light level 7 and below" rule was originally implemented on February 4, 2010, while the game was still in its Indev phase, and remained constant since with the exception of Java Edition Alpha v1.2.0 through Java Edition Alpha v1.2.0_02, where the restrictions were height based.
- This is not the first "experimental snapshot", as it was preceded by Java Edition Combat Tests, but this is the first one to be available on Minecraft.net and the first to lead to a proper snapshot.
- This is the first time the terrain has been changed since Java Edition 1.13 in 2018, and is the first time the terrain has been completely overhauled since Java Edition 1.7.2 in 2013.
- Unlike later experimental snapshots, the title of this version is in title case.
