Vray and Corona versions included

For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured with PBR in mind.

V-Ray versions are 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 suits you best"
