If you're using a V-Ray version earlier than 3.1, please note that the BRDF section in the materials displays Microfaset GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Select Blinn, Phong, or Ward – whichever is more convenient for you.

For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of materials is configured taking PBR into account.
