UnderMod Mod (1.20.1) – Survive Ancient Sewers and Sail Deep Underground Rivers

Description

UnderMod Mod fills the world beneath your feet with connected underground biomes. It generates giant ancient sewers under villages, hidden forests, and deep rivers that stretch across the map. You can travel through these connected caves to find new blocks and hidden dangers. The mod changes how you play underground without breaking your existing Minecraft worlds.

• Procedural Layouts: Generates unique underground areas every time to keep cave generation fresh.
• Links faraway underground areas together, like sewers pouring into underground rivers.
• Works perfectly alongside other world generation mods you might already have installed.
• Runs smoothly with an optimized generation engine to keep lag low.
