Simplex Terrain Generation Mod 1.16.5, — Reference

Biome Regions

Biomes are distributed based on the final height calculated by the noise engine. This creates a natural progression from deep oceans to frozen peaks. The world is divided into 7 vertical regions:

• Y0 – Y29: Deep Ocean variants.
• Y30 – Y60: Standard Ocean variants.
• Y63 – Y66: Beaches and coastal biomes.
• Y67 – Y90: Lowland biomes (Plains, Forests).
• Y91 – Y140: Mid-altitude biomes (Hills, Savannas).
• Y141 – Y190: High-altitude biomes (Mountains, Taiga).
• Y191 – Y256: Alpine biomes (Snowy Mountains, Peaks).

As the height increases, the mod automatically weights the biome selection toward colder climates to simulate realistic temperature drop-off.
