Who works with V-Ray version lower than 3.1, pay attention to materials section BRDF (Microfaset GTR (GGX)), if your version is older than 3.1 - this section will be empty, and you have to choose: Blinn, Ward or Phong , d dependence on material.
.
For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured considering PBR. Do not use scripts for converting from Corona to Vray. There are some Maps ( like Corona BitMap ), which cannot be converted with automatic Script and it will be some Missing textures, like Corona BitMaps, which VRay cannot render. Convert all materials manual.
