Renders for the preview were made in Corona Render 12. On the Corona Legacy Mtl model. Corona Render version 1.5 or higher is required. Materials were converted to V-Ray using V-Ray scene converter.

All my models are optimized, made for anti-aliasing (where it is needed). They do not have unnecessary geometry and unjustifiably heavy maps. All archives are as light as possible without losing quality. All objects and materials are logically named.

"For Corona Render: it is recommended to install version not lower than 1.5, since the glossiness of materials is configured taking into account PBR.

Those who work in V-Ray version lower than 3.1, be careful. In the materials in the BRDF section there is Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - what is for you "preferably."
