**********
BE CAREFUL: !! Vray 3.6. In the version below 3.1, be careful – in some materials in the BRDF section there is Microfaset GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong or Ward – which is preferable for you.
!! Corona 5. For Corona render, it is recommended to install version 1.5 or higher, as the glossiness of materials is adjusted with PBR in mind.
