"For Corona Render, it is recommended to use version 1.5 or higher, as the glossiness of the materials is set considering PBR. If you are using V-ray version lower than 3.1, please be careful. In the materials under the BRDF section, Microfaset GTR (GGX) is set; if your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward - whichever is preferable for you."
