If you are working in V-Ray version lower than 3.1, be careful, the materials in the BRDF section are 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 consideration for PBR.
