About this Mod
Extended Build Limit is designed for builders, terraformers, and modpack creators who find the standard Minecraft world height too restrictive. Whether you are building a space elevator reaching into the clouds or a sprawling subterranean empire in the deep dark, this project removes the invisible walls holding you back.
🚀 One Project, Two Ways to Play
To ensure maximum compatibility for every type of player, Extended Build Limit is distributed in two formats:
- As a Mod: Drop the .jar into your mods folder for a seamless, automated setup. Supports Fabric, Quilt, and NeoForge.
- As a Datapack: Perfect for vanilla servers or players who prefer not to use mod loaders. Simply add the .zip to your world’s datapacks folder.
✨ Key Features
- Massive Verticality: Extends the building range far beyond the standard $Y = -64$ to $Y = 320$.
- Seamless Integration: Fully compatible with major world-generation mods like Terralith, Tectonic, and Nullscape.
- Vanilla Friendly: Does not add new blocks or items, ensuring your world remains "vanilla-plus" and safe for future updates.
- Server-Side Optimized: Optimized to maintain high TPS (Ticks Per Second) even with the increased chunk data.
📖 Installation Guide
For Mod Users
Download the version corresponding to your loader (Fabric/Quilt/NeoForge).
Place the file in your .minecraft/mods folder.
Launch the game and create a new world (or backup an existing one).
For Datapack Users
Download the .zip version of the project.
In the Minecraft World Selection screen, click Edit > Open World Folder.
Place the zip file into the datapacks folder.
Run /reload in-game or restart the world.
⚠️ A Note on Performance: Increasing the build limit increases the amount of data per chunk. While this project is optimized, players on lower-end hardware may need to adjust their render distance for the best experience.
