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

Enjoy your use and successful projects =)
