GeoTectonic

Vanilla's tangle of noodle caves is gone. In its place the underground is solid rock cut by eight hand-designed cave systems, each with its own shape, biome rules and reward for finding it.

What's new

GeoTectonic 2.0.0

  • Added: Support for every Minecraft version from 1.20.1 to 1.21.1: Fabric on all of them, Forge on 1.20.1 to 1.21 except 1.20.5, which Forge never released, and NeoForge on 1.20.4 to 1.21.1, with one download in place of a separate file for each Minecraft version.
  • Added: A settings screen for every setting, opened from Mod Menu on Fabric and from the Config button in the mod list on Forge and NeoForge.
  • Added: A chat message with a download link when a newer GeoTectonic is out for your Minecraft version and loader, checked once per game start and turned off with check_for_updates in config/geotectonic.toml.
  • Added: A [tectonic] section in config/geotectonic.toml that turns each of Tectonic's caves, noodle caves, lava tunnels and underground rivers back on or off separately.
  • Added: The Dry Passage, a long, wide, winding tunnel deep underground, carved dry, with a little amethyst and a few ores in its walls and its own subtitle, advancement and ambient sound.
  • Added: A setting to generate Karst chambers without their pool of water.
  • Added: With Terralith or YUNG's Better Caves installed, their caves are filled with rock as vanilla's are, each with its own switch in config/geotectonic.toml.
  • Changed: The Forge build accepts Forge 47.1 and later, so it also runs on the NeoForge 1.20.1 fork.
  • Removed: GeoTectonic no longer requires Architectury API or Cloth Config.
  • Fixed: /geotectonic find finds caves it used to miss and /geotectonic stats counts the chunks where each cave really starts, both following the order in which the world places carvers.
  • Fixed: On Fabric, GeoTectonic's caves are placed in overworld biomes only, as on Forge and NeoForge, instead of in every biome, and on Minecraft 1.20.1 to 1.20.4 a world with GeoTectonic no longer opens the "Worlds using Experimental Settings are not supported" screen each time it loads.
  • Fixed: Tectonic's underground rivers are kept instead of being filled with solid rock where GeoTectonic generates chunks.

GeoTectonic 1.0.3

  • Fixed: /geotectonic help lists every cave type, including sea_cave, crystal_vein and volcanic_vent.
  • Fixed: All eight GeoTectonic advancements load again on Minecraft 1.21.1.

GeoTectonic 1.0.2

  • Changed: Command help and the cave distance message use a plain hyphen instead of a long dash.
