How do I install Cave Additions?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does Cave Additions work with?

The listing gives Minecraft 1.19.4, 1.21.1, 1.20.1, among others. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

cave additions is a mod that overhauls caves

places random patches of cobblestone, mossy cobblestone, coarse dirt, and dirt to caves to improve the visual aspect of cave exploration. // all versions
also adds new terrifying cave biomes and new mobs to caves (only for non-purity versions) // all Impure versions with biomes cause world corruption ; Blue edition is being made to be a more stable version of the mod.
adds cave greeble and some unique underground biomes via terrablender. (only blue edition versions)

the mod requires geckolib if it is a Impure version, the purity versions only have the cave greebling. (coming soon for the 1.20.1 version)

Additionally ;

this should be compatible with a large amount of modpacks ; but may and will cause unexpected behaviors (non-purity versions)

this should be compatible with 99% of modpacks (Purity versions)

this should be compatible with most modpacks (Blue edition versions)

Impure versions are extremely liable to cause world corruption and are bug nests overall.

Blue edition versions will be Impure versions without the crashes and world corruption.

Purity versions are extremely stable as they are quite literally glorified datapacks.
