Render created in Corona 6.
Materials in Vray were converted using a converter.

For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of materials is configured taking into account PBR.
If you're using a V-Ray version earlier than 3.1, be careful: the BRDF section in your materials will show Microfaset GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward—whichever is more convenient for you.
