"For Corona render: it is recommended to use a version no 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 BRDF, Microfaset GTR (GGX) is set; if your version is older than 3.1, then it is preferable."
