Nightosphere Data Pack (26.1.2, 1.20.1) – Improved Underground Design

Nightosphere Data Pack is a datapack that makes light changes to the Nether generation with level design in mind. It keeps the same biome distribution but improves the overall structure and gameplay experience. The changes focus on making the Nether taller, removing frustrating barriers, improving resource generation, and adding helpful features for travel. All changes are designed to make exploring and mining in the Nether more fun and less annoying.

Features:

• Increases Nether height up to 224 blocks (effectively 192 usable space)
• Top 32 layers are netherrack with small caves for more open areas
• Caves don’t go below the lava ocean level anymore
• Removes impossible-to-cross lava barriers that stop exploration
• More quartz ore spawns throughout the Nether
• Makes quartz easier to find for building and getting experience
• Ancient debris generates more scattered in single blocks
• Higher chance of finding netherite even in smaller amounts
• Makes searching for netherite less random and frustrating
• New cave rivers at lava sea level for easier strider travel
• Giant crimson and warped fungi now check terrain before placing
• Stops fungi from generating in small spaces where they look broken
• Basalt delta columns are no longer hardcoded
• More structure-friendly generation system
• Same biome distribution as vanilla Nether
