If you are using V-Ray version lower than 3.1, please note that in the materials section BRDF 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 version no lower than 1.5, as the glossiness of materials is set taking into account PBR.
