Those who work in V-Ray versions 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 – whatever suits you best.

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.
