Who works in the V-Ray version is 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 the BRDF field will be empty. Choose Blinn Phong or Ward – which is preferable to you.

For Corona render it is recommended to install a version not lower than 1.5 since the glossiness of materials is customized taking into account PBR

Enjoy using and beautiful renders!
