The model uses Corona Legacy Mtl. All objects and materials are logically named, and the material maps duplicate the names of the materials and the slots to which they are connected.

The renders for the preview were created in Corona Render 9.3.

For Corona Render: it is recommended to use a version no lower than 1.5, as the glossiness of the materials is set with PBR in mind.

Material conversion to V-Ray was performed using the V-Ray scene converter. If you are working in V-Ray version lower than 3.1, be cautious. In the materials section BRDF, Microfaset GTR (GGX) is set; if your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.
