Amplified Nether Fix Biome

Amplified Nether Fix Biome

Overview

This mod fixes the biome detection issue in amplified Nether worlds where biomes above Y128 (the Nether roof) incorrectly show as “Plains” instead of their proper Nether biome types. When used with amplified Nether mods that increase the Nether’s height to Y256 or higher, this ensures that Crimson Forests, Warped Forests, Soul Sand Valleys, Basalt Deltas, and Nether Wastes extend their biome detection vertically up to Y512.

Features

• Extends Nether biome detection vertically from Y0 to Y512
• Maintains proper biome assignment (Crimson Forest remains Crimson Forest, etc.)
• Compatible with amplified Nether mods that increase world height
• Fixes farms and gameplay mechanics that depend on correct biome detection on the Nether roof
• Works seamlessly with existing world generation

How to Use

1. Install this mod alongside your favorite amplified Nether mod
2. Start or load your existing amplified Nether world
3. Travel above Y128 to the Nether roof
4. Observe that biomes now correctly match those below (e.g., Crimson Forest above Y128 is still Crimson Forest)
5. Build farms and structures that depend on biome-specific mechanics

Tips & Tricks

• Combine with “Amplified Nether” or similar height-extending mods for best results
• The mod repeats biome patterns every 128 blocks vertically, maintaining consistency
• No configuration needed – works automatically
• Safe to add to existing worlds

Known Limitations

• Only affects the Nether dimension (other dimensions unchanged)
• Maximum extended height is Y512 (can be adjusted in future versions if needed)
• Biome detection above Y512 will revert to default behavior
