[[File:1.18 Experimental Snapshot 1 approximate ore distribution.jpg|thumb|300px|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=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 [[biome]]s, with biomes adapting to whatever [[terrain]] they happen to generate throughout.{{YouTube link|6Ffu1gTEsVo|Minecraft 1.18 experimental snapshot|Henrik Kniberg|July 13, 2021|name=}} ** This allows for natural variation in the terrain of any individual biome, both in terms of shape and elevation. *** For example, [[forest]]s and [[desert]]s 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. ; [[World type]]s * Removed the "[[Large Biomes]]" and "[[Amplified]]" world types. == Gallery == TaigainPlains.png|Taiga village generated in plains biome in experimental 1.18 snapshot.
