About this Mod
Dimension Expansion
A Dimension Mod for Minecraft 1.21.1, inspired by Extra Utilities 2 – Deep Dark and The Beneath / Deep Dank Discover The Deep Beneath, a vast underground realm of eternal night, thick darkness, and relentless danger.
The Mining Dimension inspired by Aroma1997s Dimensional World as well as other more modern takes on Mining Dimensions. Our mining dimension is flat with no features except ores underground.
And a Stoneblock dimension, which is only working conceptually. It's obviously inspired by the same named modpacks but really the goal here is to add a dimension that could be utilized in modpacks for different purposes or maybe in lieu of the mining dimension.
The Mining Dimension
A peaceful alternative for resource gathering.
- A superflat world with a large layer of Stone, then Deepslate, then Netherrack and then End Stone with ores in each layer. but with no caves or caverns.
- Completely free of hostile mobs.
- Higher Y-level (Y=208) terrain for large-scale mining or automation builds.
The Stone Block Dimension (not fully implemented)
A true builder’s dream — or miner’s challenge.
- Solid from bedrock to bedrock (-64 to 320).
- Filled entirely with stone and deepslate, packed with ores.
Fully Data-Driven and Customizable
All dimensions are configurable via datapacks, letting you tweak:
- Ores and biome features
- Mob behavior and spawn rates
- Noise settings, blocks, and light rules
For modpack developers, this means you can completely reshape these worlds without touching code.
See the GitHub Wiki for detailed guides on datapack customization, noise settings, and mod integration.
Actively Developed
These dimensions are only the beginning — expect more biomes, structures, and challenges in future updates. Have ideas or feedback? We’d love to hear from you.
