A material defines the apperance of a model. Currently, we support the “StandardMaterial” from babylon.js but more will follow in the future. Materials can be defined in the material section of the scene object or inline as property of a mesh. Defining them in the material sections ensurse that they are parsed before any scene element and therefore you can reference and use them from any mesh in your scene.

To see the different materials in action, please check out our material editor sample.

PBR Metallic Roughness Material

This is a simpler version of the PBRMaterial with limited options. Usually this is more then enough and performance-wise it makes sense to use this limited version if you don’t need any of the features of the more sofisticated version.

    "type" : "PBRMetallicRoughnessMaterial",
    "baseColor" : [ number, number, number],
    "baseTexture" : Texture,
    "metallic" : number,
    "roughness" : number,
    "metallicRoughnessTexture" : Texture,
    "environmentTexture" : Texture | CubeTexture
}
