Nether API Mod (1.12.2) – Explore Taller Nether Caverns Filled

Nether API Mod connects different dimension mods so custom Nether and End biomes generate together without conflicts. It fixes how older mods build worlds and lets new plants grow across matching modded soils. The mod also lets you explore taller Nether worlds with deep caves that cut right through soul sand and surface blocks.

Features:

• Unifies Nether biome generation from different mods under one shared system.
• Combines End biome generation so separate mods work together in the same world.
• Lets you increase Nether height up to 256 blocks tall for massive underground spaces.
• Caves can now generate naturally across the outer islands of the End dimension.
• Nether caves carve through surface blocks, filler blocks, and soul sand instead of stopping at netherrack.
• Adds custom biome ambience with passive background sounds, dark cave noises, and floating particles.
• Fixes cascading world generation lag when the game creates Nether and End chunks.
• Helps modded plants grow on matching soil blocks from other mods, including End Stone and Netherrack variants.
• Prevents custom structures from colliding or overlapping during world generation.
• Custom structures registered with this mod work directly with the locate command in chat.
• Lets you choose a custom default dimension for player respawns.
• Lets you turn off the initial Ender Dragon fight while still spawning an End Gateway on arrival.
