Cavern mods

[Honeypot]

Can anyone guide me which is the best environment mod(biomes) for underground caverns in minetest as there are a ton of them and I am a bit confused which one to use for the game I am working on as I want to make proper use of the great vertical height The Minetest Engine is capable of handling .
Thanks in advance.

Most of the core mapgens already have massive caverns 100s of nodes high and up to 1000 nodes long.

But the caves are just … well … holes in the underground stone :)

Maybe check out Cave Realms Lite or underground biomes to add something to look at in caves. Personally I use Cave Realms Lite (and World borders for some kind of “natural barrier” at the bottom of worlds).

It also worth reading into world generator configuration and slightly tweak it. I don’t know my exact values anymore, but in result my caves are thousands of nodes deep with giant underground halls.
