Those who work in V-Ray versions lower than 3.1 be careful, the materials in the BRDF section contain Microfaset GTR ( GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward, whichever is preferable for you.

For Corona render, it is recommended to install a version not lower than 1.5, since the glossiness of the materials is configured with PBR in mind.
