For V-Ray render 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 manually.
