About this Mod
No Caves
Don't want caves? You're in luck! This datapack removes them. There are still underground features and structures (Ancient Cities, Strongholds, Mineshafts, Amethyst Geodes, Lava Pools, Ores, etc.) but no more caves. Additionally, this datapack has sister versions that remove specific types of caves, like only removing the new caves or old caves. The datapacks now work with the Large Biomes and Amplified Presets!
No Caves
Removes all caves
No Old Caves
Removes all the old carver caves, leaving just the 1.18+ caves (noise caves)
No New Caves
Removes all of the 1.18+ caves (noise caves), leaving only the classic carver caves
Compatibility Notes:
In order to use this with other packs, No Caves must be the top-most level datapack (e.g. it should appear higher on the list, above other datapacks).
Compatibility has to be made manually depending on how the mod handles their caves. Sometimes, it is done automatically though, it just depends on what they do. That being said, I plan on adding support for mods like Tectonic, Terralith, and more.

Server lagging with No Caves – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if No Caves consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
