Who works in 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 preferable for you

For Corona render it is recommended to install at least version 1.5 since the glossiness of the materials is adjusted with PBR in mind.
