If you are working in V-Ray version lower than 3.1, be careful, in the materials section BRDF, it is set to Microfaset GTR (GGX); if your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.

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