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) if 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 of at least 1.5 since the glossiness of materials is configured with PBR in mind.
