For those working in V-Ray versions lower than 3.1, please note that the materials in the BRDF section are set to Microfaset GTR (GGX). If your version is older than 3.1, that 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 with PBR in mind.
