Select both the Behavior Pack and Resource Pack folders. Compress them into a single .zip file. Rename the file extension from .zip to .mcaddon . How to Install Your Patched MCADDON Once your file is ready, installing it is straightforward:
Automated asset conversion often leaves errors that cause Bedrock to reject the add-on. Manual patching ensures your mod elements render and function properly. 1. Patching blocks.json and texture_list.json
Inside your Resource Pack folder, create a file named manifest.json .
Ensure all images are in .png format. Bedrock is highly sensitive to file paths; make sure your textures/terrain_texture.json and textures/item_texture.json point exactly to the corrected file locations. 2. Patching Geometry in Blockbench
Use the Bedrock Scripting API to replicate Java interactions that JSON cannot handle. 6. Package to .mcaddon Select both the behavior_pack and resource_pack folders. Compress them into a single .zip file. Rename the extension from .zip to .mcaddon . 7. Installation how to convert jar to mcaddon patched
Note: Ensure all file names use lowercase letters and underscores only. Bedrock is strictly case-sensitive and does not tolerate spaces or capital letters in asset paths. Converting 3D Models via Blockbench Open . Go to File > Import > Java Block/Item Model .
Go to a free online UUID generator. Generate four distinct strings. Replace the placeholder text in your JSON files with these unique keys. Notice that the dependencies section in the Behavior Pack manifest must exactly match the first header UUID of your Resource Pack. This links the two packs together. Step 4: Patching Common Broken Files (The "Patched" Phase)
:
Once the folders are organized and your patched manifest.json is ready, compile the contents back into a Bedrock format. MyConvertedMod

A .jar file is fundamentally a compressed ZIP file containing Java classes and asset folders. To modify the inner files, you must first convert it to a standard archive:
: Test conversion with a small mod (single block or item) before tackling complex ones. PortKit’s MVP verification uses simple block mods like simple_copper_block.jar for this reason.
Define a terrain_texture.json file to assign short identifiers to your block texture paths. Rename the file extension from
Mods that drastically alter core player physics or dimensions. Step-by-Step Guide to Converting JAR to MCADDON Step 1: Source the Correct Java File
Contains compiled Java code ( .class files), textures, and assets. .mcpack : A Bedrock resource or behavior pack container.
Java models (often hardcoded in Java classes) frequently break or render invisibly when pushed into Bedrock JSON formats. Open .
Java .json models must be converted to Bedrock .geo.json using Blockbench.
: Java texture folders use an assets folder tree. Bedrock expects a flat or structured layout split into Resource Packs (textures, sounds, models) and Behavior Packs (logic, loot tables, component variables).
