ANBL - (Almost) No build limit

by Nachtwind1

ANBL raises the world build limit so terrain can reach from y -1024 up to y 1024, far beyond the vanilla height range.

What it does

Vanilla worlds stop at a fixed height and depth. ANBL lifts the top of the build area to 1024 and lowers the bottom to -1024, giving servers a much taller and deeper world. Mountains can rise higher, and the generator can carve caves that span a far larger vertical distance than in standard worlds. Terrain is also amplified, so peaks grow bigger and floating islands can appear above them. Server owners who want very tall mountains or deep underground systems can use it to explore that scale. Files are published for Fabric, Forge, NeoForge and Quilt for game versions 1.19 – 1.21.4, and a data pack version is available too.

Key features

  1. Extended build height

    Build height is raised to y 1024 and the lower limit drops to y -1024.

  2. Taller mountains and deeper caves

    World generation produces mountains and cave systems across a vertical range that reaches far beyond vanilla.

  3. Amplified terrain

    Terrain is amplified so peaks grow larger and floating islands can form above the mountains.

How it compares

Full comparison

Extended World Height (Y=1024) is open source under the BSD 3-Clause License and supports versions 1.20 – 26.3 on the same four loaders. Nie's Higher Build Limit (512) is not open source, is licensed as All rights reserved and covers 1.19.3 – 26.1.2, so ANBL offers a much higher ceiling than that option.
