Caves & Cliffs Prototype Data Pack

The Caves & Cliffs Prototype Data Pack is an official data pack that was released periodically by Mojang Studios from April 2021 to May 2021.Caves & Cliffs Prototype Data Pack for Minecraft Java Edition – feedback.minecraft.net It contains several experimental and work-in-progress features, most of which were eventually released in Java Edition 1.18. Its first release coincided with the announcement that Caves & Cliffs would be split into two major updates. The data pack was eventually superseded by experimental snapshots as changes that are too large for a data pack were introduced.
== Features ==
; Items
* Bundles can be crafted once again.
; General
* The height limit has been expanded 64 blocks up and 64 blocks down to a total of 384 blocks, with Y=319 being the limit upward and Y=-64 being the limit downward.
; World generation
* Deepslate blobs no longer generate above Y=0.
* Diorite, granite, and andesite blobs are larger and more spherical, but less common.
* Underground generation has been extended 64 blocks down to go along with the downward height expansion.
** Deepslate makes up a majority of the expanded area, with the stone above gradually transitioning to it from Y=-1 to Y=-7 until it is completely replaced by deepslate at Y=-8.
*** Certain types of ores and structures still generate in the deepslate layer, as well as tuff.
*** Dirt, gravel, diorite, granite, and andesite do not generate in this layer.
** Lava replaces air below Y=-53 instead of below Y=11.
** The bedrock layer has been moved down to Y=-64.
* Fossils are able to generate at any height instead of just between Y=40 and Y=49.
** Fossils below Y=0 generate with deepslate diamond ore instead of coal ore.
* Caves have been completely overhauled.
** Now stretch down to Y=-59.
** New noise caves, coming in three forms: cheese, spaghetti, and noodle.
*** Cheese caves have large stone columns stretching from the bottom of the cave to the top.
**** Very large, often large enough to fly through 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.
** Contain aquifers, bodies of water with different heights, independent of sea level (Y=63).
*** Only used below Y=31, meaning any noise caves between Y=31 and Y=63 are flooded with water.
*** Aquifers below Y=0 sometimes generate with lava instead of water.
** The original carvers still exist with their generation slightly tweaked to add more variation and to better blend in with noise caves.
** New crevice carvers, which are deep, long cracks in the ground that are thinner and straighter than canyons.
* Ore veins, long and rare formations of ore and rock, have been introduced.
* Changed the generation of all ores, making them have a spread value like lapis lazuli ore. Some still retain a linear generation alongside a spread generation.
** Copper ore generates between Y=0 and Y=96, and uses spread like all other ores. 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.
** 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=64.
** 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 generates below Y=16 as a spread, peaking at Y=-64 and decreasing in quantity as the altitude increases.
