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 considering PBR. Those working in V-Ray versions lower than 3.1 should be cautious.
In the materials section, BRDF is set to 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.
