Cave Expansion Mod 1.12.2 (Adds Tons of New Structures Below the Surface)

Cave Expansion Mod 1.12.2 adds several new blocks: clay and stone pots, treasure chests. Each block drops valuables when destroyed. Pots drop various useful items such as torches and food, arrows, etc. Chests drop more valuable things such as diamonds, iron ingots or even tools and armor. The main goal of this mod is to diversify the boring and empty Minecraft underground. The mod adds more than a hundred different randomly generated structures. All of them are handmade and can be traps, dungeons or just tunnels or empty rooms. Some structures are restricted to spawn in set biomes, for example, deserts have sandstone dungeons, pyramids, and tombs underneath the surface, jungles have mossy structures and poisonous traps with tripwires. Mod is 100% vanilla-friendly and doesn’t add any custom items, so you can add it to any mod pack. Be careful, some structures have explosive elements!

(Recommend installing this mod with any cave generator mod, for example, Worley’s Caves or YUNG’s Better Caves.)

If you want to adjust the frequency of structure generation in the world, you can use the command /caveexpansionfrequency (or just enter “/cave” and hit [Tab]) and enter the chance multiplier. For example, “/caveexpansionfrequency 0.5” will set half as many structures or “/caveexpansionfrequency 2” – twice as many. This would only affect newly generated chunks and the multiplier will be set only for the current world. Setting the value too high (more than 5) may cause lag when generating new chunks.

All structures created with Minecraft structure blocks and structure void blocks.
