In the Multi / Sub-Object material there are four color options: white, anthracite, blue and beige.
Turbosmooth stack is not collapsed.

Who works in the V-Ray version lower than 3.1, be careful, in the materials in the BRDF section there is a Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - which is preferable to you.

For Corona render, it is recommended to put a version not lower than 1.5, since the glossiness of materials is adjusted to fit PBR.
