World Height Limit
by SORFIN
World Height Limit raises the build height of a Minecraft world, generating a version-aware datapack inside the world save folder on Fabric and NeoForge.
What it does
The mod expands the world height beyond the vanilla limit by generating the required dimension datapack automatically. Heights are configurable up to Minecraft's stable validated limit, and the generated datapack is aligned to the 16-block world sections the game uses. The effective generated height is reported, and debug diagnostics help confirm what a world is actually running.
Fabric and NeoForge builds are current beta releases and focus on world height expansion, datapack generation and configuration. Diagnostics cover both singleplayer worlds and dedicated servers. Bukkit-based server platforms (Bukkit, Spigot, Paper, Purpur and Folia) are supported as well, where building above the vanilla limit can be restricted to admins or players with a permission.
The mod covers Minecraft 1.19 – 1.21.11 with 24 release versions. Its Fabric and NeoForge files are published under the Apache License 2.0, and the code is open source. Source code, an issue tracker and a wiki are linked from the project.
