Aoyama's Nocaves+more
by AoyamaATM
Aoyama's Nocaves+more is a Forge world generation mod for Minecraft 1.12.2 that switches off caves, ravines, underground lakes and lava features, one by one, in the Overworld and the Nether.
What it does
The mod works through Forge's terrain generation events, so each feature can be enabled or disabled in the configuration file. Caves, ravines, underground water and lakes, lava lakes, lava springs and single-block lava pockets are all covered. Changes made in the Mods menu of the configuration take effect after the world is reloaded, but chunks that already generated keep their caves and lakes, so new terrain must be generated to see the result.
The mod also handles Nether caves and Nether lava generation, which are disabled by default through the removeNetherCaves option. Cave generators from other mods, such as Worley's Caves, replace the vanilla cave generator, and the mod's event handling order accounts for that replacement. Compatibility is not assured with mods that create underground cavities through completely independent systems rather than Forge's standard terrain generation events.
Installation needs only Forge for 1.12.2; the environment is client and server, and the mod is released under the MIT License as open source. Files target 1.12.2 alone, with 2.0.0 the latest, published on 2026-08-26.

No Worldgen 5 You Continued is a Forge mod for 1.12.2 that works on either side, and neither side needs it, and it is open source under the GNU General Public License v3.0 only. Aoyama's Nocaves+more is client and server, MIT licensed and only for 1.12.2.
