For Corona Render, it is recommended to use a version of at least 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 cautious. In the materials, the BRDF section has Microfacet 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.
