"For Corona Render: it is recommended to use a version not lower than 1.5, as the glossiness of the materials is set with PBR in mind.

Those working in V-Ray versions lower than 3.1 should be careful. In the materials section, the BRDF is set to Microfaset GTR( GGX ), if your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you."
