📖 Overview

1.21.11 Java Item Backport is a lightweight Fabric utility/library mod for Minecraft 1.20.1.

As Minecraft's internal model engine updates, map makers, modders, and resource pack creators often face limitations when trying to implement modern JSON models on older versions. By porting the handling of 1.21.11+ block and item JSON models, it allows them to be natively read, loaded, and rendered perfectly in 1.20.1.

✨ Features

• Modern Model Formatting: Seamlessly load block and item model JSONs formatted for the newest Minecraft versions.
• Arbitrary Rotation Angles: Break free from the standard 22.5° limits! Full support for complex, multi-axis arbitrary rotation angles generated via Blockbench.

🛠️ For Developers / Modders

This mod is built primarily as a library dependency for other mods to rely upon. If you are developing a mod on 1.20.1 but want to use custom models exported from the newest Blockbench versions (or rely on arbitrary rotation), easily implement this mod by depending on it.

Add it as a dependency in your fabric.mod.json:

"depends": {
  "newjavabackport": "*"
}

🎮 For Players

If another mod directed you here, simply drop the released .jar file into your mods folder. It does not add any new content by itself but provides the necessary model loading foundation for other mods to shine without crashes!
