Models are made for anti-aliasing, you can use TurboSmooth

Who works in V-Ray version below 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 you like best. For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is adjusted taking into account PBR.
