------------

For those working in V-Ray versions lower than 3.1, be careful, the materials in the BRDF section have Microfacet 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 of at least 1.5, as the glossiness of materials is set with PBR in mind.
