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

For Corona render, it is recommended to install version no lower than 1.5, as the glossiness of materials is set with PBR in mind.
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, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.
