Underground Biomes Mechanics

Underground Biomes and Strata

The mod generates "Underground Biomes" which are large regions defined by a primary stone type. Within these biomes, the stone is organized into Strata—horizontal layers of different rocks. This means as you mine deeper, you will pass through distinct bands of color and material.

Ore Overlays (UBification)

To maintain immersion, the mod uses an overlay system for ores. When an ore generates within a UB stone, it adopts the texture of that stone.

• Vanilla Support: Coal, Iron, Gold, Redstone, Lapis, Diamond, and Emerald all have UB-textured variants.
• Mod Support: Many popular mods (like IndustrialCraft, Thaumcraft, and Thermal Expansion) are supported natively or through the UB API, allowing their ores to blend into the environment.
