Immersive Cavegen
by TCLProject
Immersive Cavegen reworks underground terrain for Forge 1.7.10, with bigger caves, joined cavern systems and underground lakes that generate as the world is created.
What it does
Caves can grow larger and longer, and cave systems come in several different shapes. Caverns become larger and can link into joined systems, and they can appear in any biome. Underground water lakes and oceans are added, with oceans limited to Deep Oceans by default, though that is configurable. Mineshafts gain longer and more complex layouts, and sand generation is improved.
Underground decoration is varied: stalactites, stalagmites, cave plants, huge glowing mushrooms, vines, cobwebs and occasionally skulls. Two custom underground mobs are included, and their spawn rates can be set. Most features, along with cave and cavern frequency multipliers, the big cave spawn chance, the cave width multiplier, the filled cave level and material, and some structure toggles, are controlled from the config file.
The mod is for Forge 1.7.10 only, with the latest file 1.2g-hotfix5 released 2023-08-26. A server running it needs every connecting player to have it too. It is released under a custom license and is not open source, and the code includes parts taken from The Master Caver's Underground 4/2, which the author credits.
