Simple Speleothems Title ImageSimple Speleothems improves on Minecraft's caves by adding stalagmites and stalactites to caves to increase that semi-realistic moody factor. They come in large, medium, and small sizes and multiple stone types, including stone, deepslate, andesite, and granite (with more on the way). They can be found scattered across the floors and ceilings of naturally generated caves, including the caves of many modded dimensions (if they use vanilla stone types), such as the Twilight Forest.
From the v2.0 beta onward, the each speleothem variant (i.e. Stone Stalagmites, Deepslate Stalactites) all use one block each, no large and small variants, with blockstates controlling size and appearance for a more streamlined, interactive experience, allowing for many different sizes (small, medium, large, large plus) all using one single block, closer to vanilla dripstone.
Version 1.0 functions differently with one-block large and small speleothem variants and exists mainly as a proof of concept.

The speleothems are craftable using a stonecutter for adding a little detail to any player-made cave builds in survival. Naturally occuring speleothems will need a silk touch pickaxe to harvest. Note that stalactites will need a solid block face above and stalagmites a solid block face below or else they will break.

If water is located vertically within a certain range above a stalactite, the stalactite will drip water.

The speleothems all use the vanilla textures, so they should be compatible with any resource pack that changes those textures.

 

Implemented stone types in the latest version:
- Stone
- Deepslate
- Andesite
- Granite

 

Future plans:
Adjust generation to generate stalactites in more realistic patches or groups or clumps rather than randomly throughout a cave, more like the stalagmites
Adding speleothems for more vanilla stone types, including diorite, tuff, netherrack, blackstone, and end stone
Porting to Neoforge 1.20.6 and 1.21.1 (possibly other recent versions as I see fit)
Possible parity with existing vanilla dripstone, including crafting methods, break mechanics, falling projectile and conditional damage, player fall damage, periodic growth, water interaction, and recipes
Possible extra large speleothems variants (made of blocks)
Possibly making an additional 3D-style resource pack for dripstone to match the rest of the mod
Config to disable generation in specified biomes (possibly per stone type)
Config to disable generation in specified dimensions (possibly per stone type)

 

Known issues:
In v1.0, rarely stalagmites will generate in view of the sky even though that isn't very realistic.
Rarely a speleothem will generate on a block of a different stone type.

 

Note:
1.20.1 is the current supported version. A NeoForge 1.21.1 port is planned, but the 1.19.2 version is only a proof-of-concept demo and will not receive any further support (and does not include recipes for survival or dripping water and will retain vanilla textures when loading custom resource packs).

You are welcome to include this mod in any modpack, if you provide credit and a link to this page (Curseforge modpacks should do that automatically)
