====== Material Sets ======

Like the church, a monument can have material sets. This means that each material (base and replacement) must be listed in your monument asset property ''[[api:building#materialsetlist|MaterialSetList]]''.

For each material set, all materials must be listed in the same order as their replacement:

<code lua>
mod:register({
    DataType = "MONUMENT",
    ...
    MaterialSetList = {
        {
            SetName = "DEFAULT",
            MaterialList = {
                "MAIN_MATERIAL",
                "SECONDARY_MATERIAL",
                "TERTIARY_MATERIAL"
            }
        },
        {
            SetName = "ALTERNATIVE",
            MaterialList = {
                "MAIN_MATERIAL_ALT",
                "SECONDARY_MATERIAL_ALT",
                "TERTIARY_MATERIAL_ALT"
            }
        }
    }
})
</code>

When you import a FBX file, materials are imported alongside the model. You can find those materials in a virtual directory ''Materials'', inside the FBX file. You can see an example in the ''Example02'' mod, where the materials are in ''models/MithrilFactory.fbx/Materials''.

In this directory, you can find all your materials. You can then register an ID for each of those materials, to use them in the material set list:

<code lua>
mod:registerAssetId("models/YourMonumentModel.fbx/Materials/MainMaterial", "MAIN_MATERIAL")
mod:registerAssetId("models/YourMonumentModel.fbx/Materials/MainMaterialAlt", "MAIN_MATERIAL_ALT")
</code>

If a material is not used on the model, it will not be imported. To circumvent this, you can create a dummy object that will not be used in the mod, to apply your material on.
