For Corona render it is recommended to install version not lower than 1.5 since the glossiness of materials is configured taking into account PBR.
Those who work 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 – what is for you preferable.
