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

In V-Ray versions earlier than 3.1, the BRDF section is set to Microfaset GTR (GGX). Be careful. If your version is older than 3.1, the BRDF field will be empty. Select Blinn, Phong, or Ward, depending on your preference.
