Bigger Caves

Bigger Caves

Ever felt like vanilla caves are just a bit too small, even after the 1.18 update? This mod fixes that by simply scaling up the overall cave generation.

It tweaks the internal noise settings (cheese, spaghetti, and noodle caves) to make the underground much larger and more open. Perfect if you want to build massive underground bases or just enjoy flying through caves with an Elytra.

To use it, simply select the “Bigger Caves” World Type when creating a new world!

Features:

• Massive Caves: Significantly increases the size of all vanilla cave types, creating gigantic aquifers and open caverns.
• In-Game Customize Menu: Click the “Customize” button on the world creation screen to live-tweak the spawn rates of atmospheric decorations (like Crystal Clusters, Giant Spikes, and Glowstone Roofs).
• 100% Mod Compatible: Since this mod only changes the basic terrain shape, it works out-of-the-box with every single mod that adds new ores or biomes (like Create or Thermal). It also intelligently detects major terrain mods like Terralith to prevent conflicts!
• Lightweight: No new blocks, items, or weird mechanics. Just bigger caves.

Requires Forge 1.20.1.
You can easily drop this into any existing modpack, but keep in mind that you’ll need to explore new chunks (or create a new world with the World Type selected) to actually see the new cave generation.
