Who works in a V-Ray version lower than 3.1 Be careful, in the materials in the BRDF section there is a GTR Microphone (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - which is preferable for you.
For Corona render, it is recommended to install version no lower than 1.5, as the glossiness of materials is adjusted taking into account PBR.
