For those working in V-ray versions lower than 3.1, be careful; in the materials section, the BRDF field 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 the materials is set with PBR in mind.
