GeoTectonic
Vanilla's tangle of noodle caves is gone. In its place the underground is solid rock cut by seven hand-designed cave systems, each with its own shape, biome rules and reward for finding it.
What It Does
- The deep is solid again - vanilla cave entrances, noodle caves, cheese voids, ravines and the extra underground carvers are all suppressed, so rock is rock except where GeoTectonic cuts it.
- Seven caves worth finding, each placed by biome and depth:
- Tectonic Fracture - a narrow surface crack that descends toward bedrock, widening and branching. Every overworld biome.
- Karst Chamber - warm biomes only. A vaulted hub with satellite rooms, stalactites, calcite veins and water on the floor.
- Cenote - warm biomes only. A narrowing shaft opens into a submerged chamber lit by glow berries, with a calcite rim at the waterline.
- Erosion Cave - a winding passage near sea level with a flowing channel, moss, hanging roots and clay.
- Sea Cave - an almost fully submerged passage carved from the seafloor or a coastal cliff.
- Crystal Vein - a straight gallery at deepslate depth on a mineral fault: heavy iron, gold, copper and redstone, a diamond and amethyst alcove at one end, a sealed cave-in at the other.
- Volcanic Vent - a hydrothermal chamber with a magma floor, basalt ceiling, rising chimney, central lava source and soul fire on the walls.
- Tune every one of them - each cave type has its own per-chunk spawn chance and an on or off switch.
- Know when you find one - an optional discovery subtitle, advancement and ambient loop the first time you enter each type in a session, each toggleable on its own.
- Four commands for finding and checking -
/geotectonic find,list,statsandhelp, at operator level 4. - It knows about Tectonic - a bundled worldgen override keeps the cave suppression from being reverted by Tectonic's own datapack, forced to top resource-pack priority whatever the load order.
