For Resource Pack Creators / Mod Developers

To customize the model that appears on the player's back, create a folder inside of nicos_backslot directory, named after the ID of the item you want to modify.

Example File Structure:

assets
└── nicos_backslots
    └── backslot_data
        └── minecraft
            ├── shield.json
            └── trident.json

Each JSON file corresponds to an item and allows you to adjust its display mode, scale, offset and rotation.

Example Configuration (Trident):

{
  "mode": "none",
  "scale": {
    "x": 1.25,
    "y": 1.25,
    "z": 1.25
  },
  "offset": {
    "x": -0.5,
    "y": -1.32,
    "z": 0.5
  },
  "rotation": {
    "x": 0,
    "y": 0,
    "z": 45
  }
}
