Caves Everywhere: Descend into the Ultimate Abyss

Caves Everywhere is a massive world-generation overhaul that completely transforms the way you experience the Overworld. If you ever felt that Minecraft's caves weren't deep, dark, or terrifying enough, this is the mod for you.

We have shattered the vanilla limits to bring you a truly colossal underground survival experience!

Available for NeoForge, Forge, and Fabric (Minecraft 1.21.1).

✨ Key Features

• Colossal World Height: The world generation has been stretched to a staggering 512 blocks high!
• Subterranean Oceans: A sprawling, dark, and cinematic underground ocean waits for you at the absolute bottom of the world.
• Ancient Coastlines: Ancient Cities and the Deep Dark biome have been carefully adjusted to naturally generate along the shores and massive cliffs of the underground sea.
• The Safe Haven: The solid terrain is generated up to Y=448. Everything above that, all the way up to the Y=512 limit, is a massive open void. This is by design: it provides the ultimate safe space for dedicated players to build their giant, mob-free sky bases away from the darkness below!

⚠️ Compatibility & Warnings (Read Before Installing)

To achieve this massive scale, this mod takes absolute priority over the Overworld's noise settings and dimensional generation rules.

• 🛑 INCOMPATIBLE: You cannot use this mod alongside other overhauls that rewrite the base Overworld generation files. Mods like Terralith and Tectonic will conflict with our custom 512-block math and cause your game to crash.
• ✅ COMPATIBLE: Mods that simply add new biomes to the existing terrain using TerraBlender work flawlessly! You can safely use Biomes O' Plenty, Oh The Biomes We've Gone, Deeper and Darker, and similar mods. Our mod will naturally stretch their biomes across the new massive caves.
• ⚙️ Fabric Users: Make sure you have the official Fabric API installed in your mods folder.

🖥️ System Requirements

Due to the colossal size of the 512-block world generation, it is highly recommended to allocate 6GB to 8GB of RAM to your Minecraft instance for the best experience. Using performance mods like FerriteCore, ModernFix, and Sodium / Embeddium is also strongly advised!
