For Corona Render: It is recommended to install version 1.5 or higher, as the glossiness of materials is adjusted with PBR in mind.

If you're using a V-Ray version earlier than 3.1, be careful. In the materials, the BRDF section shows 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.
