Description

Component Materials use a special components for simply runtime Materials. It uses a component to allow for a variant of an existing json material.

Example:

{
    "modular_material": {
        "parent": "miapi:metal/iron",
        "cost": 1,
        "overwrite": {
            "hardness": 5
        }
    }
}

• "parent" Needs to refer to a json controlled material.
• "cost" The value of this item as Ingredient, defaults to 1.
• "overwrite" The json to overwrite material data of its parent. Works the same a a Material Extension.

Example command

/give @p minecraft:stone[miapi:modular_material={
    "parent":"miapi:metal/iron",
    "overwrite":
        {
            "icon":{"type":"item","item":"minecraft:dirt"},
            "translation":"Dirt ",
            "color_palette":{"type":"image_generated_item","item":"minecraft:dirt"}
        }
    }
]

Overall, a better structure for this are Composite Materials, as they offer greater flexibility in most scenarios. But for quick testing this still offers some value.
