The model is made under TurboSmooth. Preview renderings were made in Corona Render 9.2. On the Corona Legacy Mtl. Conversion of materials to V-Ray was done using V-Ray scene converter.

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 V-Ray versions 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.
