Merging Minecraft Resource Packs

Combining multiple resource packs can enhance your Minecraft experience by integrating various models, textures, and items. This guide will walk you through the process of merging packs effectively.

📁 Understanding Pack Structure

When merging packs, it's essential to understand their structure. Consider a resource pack named “Funky Furniture RP”:

Funky Furniture RP/
└── assets/
    └── minecraft/
        ├── models/
        │   ├── item/
        │   │   └── paper.json
        │   └── custom/
        └── textures/
            └── custom/

Key components to merge:

Contents of the models/custom/ directory.
Contents of the textures/custom/ directory.
The base item's .json file (e.g., paper.json in models/item/).

🧩 Merging Models and Textures

Copy the custom folders from both models and textures into your existing resource pack's corresponding directories.
Ensure that the directory structure remains consistent to avoid reference issues.

🛠️ Updating the Base Item's JSON

The base item's .json file (e.g., paper.json) contains overrides that link custom_model_data values to specific models. Here's an example:

{
  "parent": "minecraft:item/generated",
  "textures": {
    "layer0": "minecraft:item/paper"
  },
  "overrides": [
    {"predicate": {"custom_model_data": 1}, "model": "custom/funky_chair"},
    {"predicate": {"custom_model_data": 2}, "model": "custom/funky_desk"},
    {"predicate": {"custom_model_data": 3}, "model": "custom/funky_lamp"}
    // Add more overrides as needed
  ]
}

To merge, append the new overrides entries from the additional pack into your existing paper.json. Ensure that each entry is separated by a comma, except for the last one.

✅ Finalizing the Merge

After merging the models, textures, and updating the base item's .json file:

Load your resource pack in Minecraft.
Use commands or gameplay to obtain the items and verify their appearance.

If everything is set up correctly, your merged items should display as intended.
