Who works in the V-Ray version lower than 3.1 be careful in the materials in the BRDF section there is a Microfaset GTR (GGX) if your version is older than 3.1 then the BRDF field will be empty. Choose Blinn Phong or Ward – which is preferable to you. For Corona render it is recommended to put a version not lower than 1.5 since the glossiness of materials is adjusted to fit PBR.
