The model uses CoronaLegacyMtl and V-RayMtl

Renders were made in Corona 11 materials were converted to V-ray using V-ray converter

For Corona render it is recommended to install version no lower than 1.5 since the glossiness of the materials is adjusted taking into account PBR

Those who work in a 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 – whichever is preferable for you
