The render was created in Corona 6.
Materials in Vray were converted using the converter.

For Corona render, it is recommended to use version no lower than 1.5, as the glossiness of materials is set considering PBR.
Those working in V-Ray version lower than 3.1 should be careful, in the materials section BRDF is set to Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.
