Hello, I'm FurrO2, i'm new here and don't really know how to use Github well, sorry in advance ! I don't have much talent in the development field, but I've been trying to create a Java resource pack converter to Bedrock for the game, capable of supporting versions higher than 1.21.4. My mission is to offer a simple tool that allows anyone to easily convert a Java resource pack in just a few clicks, making it compatible with Geyser.
Thank you.
This script automates the conversion of a Minecraft Java Edition resource pack to Bedrock Edition, especially handling Custom Model Data (custom_model_data) items.
- 🔁 Automatically converts Java JSON models to Bedrock-compatible geometries (
.geo.json) - 🖼️ Copies item textures
- 🧱 Generates custom items based on
custom_model_data - 📁 Creates a ready-to-use Bedrock Edition folder structure
- 🧩 Supports both
elementsandgroupsin models - ✅ Compatible with Geyser for cross-platform servers
- Python 3.7 or higher
- Python module:
pyyaml
Install with:
pip install pyyaml
📁 Java Pack Structure Required
The script expects your Java resource pack to be structured like:
java/ assets/ minecraft/ models/
📁 Output Bedrock Structure It will generate:
bedrock/ textures/ models/ entity/ render_controllers/
Run the script:PackConverter_JavaToBedrock.py
Choose your language (Fr is the default language, En is also available)
Locate your Java resource pack folder with the GUI/Panel directory. (Do not use a zip file.)
Click the Start Conversion button.
A .zip file will be generated containing your pack and the Geyser mappings.
You're done! Review the contents, then rename the .zip file to use the .mcpack extension.
