# Custom model data and leather armour

Custom model data and leather armor for ManticSets items.

## Custom model data

Set `data` inside an armor item's object under `set`. On Minecraft 1.14 and newer, a positive value is used as CustomModelData. On older versions it is applied as item durability.

```yaml
set:
  helmet:
    type: DIAMOND
    data: 1234567
  chestplate:
    type: DIAMOND
    data: 1234568
```

Use `data: 0` when the item does not need a custom model value.

## Coloured leather armour

Add an RGB colour to the leather material type. Configure each slot separately when pieces need different colours.

```yaml
set:
  helmet:
    type: "LEATHER:255,255,255"
  chestplate:
    type: "LEATHER:255,255,255"
  leggings:
    type: "LEATHER:255,255,255"
  boots:
    type: "LEATHER:255,255,255"
```
