The objects have the Turbosmooth modifier applied, enabled (geometry for smoothing).
Adjust the smoothing level as needed.

For Corona Render: it is recommended to use version 1.5 or higher,
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 section BRDF, Microfacet GTR (GGX) is set; if your version is older than 3.1, the BRDF field will be empty.
Choose Blinn, Phong, or Ward – whichever is preferable for you.
