Materials for V-Ray were converted using V-Ray Scene Converter.
Rendering done in Corona Renderer 10

For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of the materials is adjusted taking into account PBR

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