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.
