If your version of VRAY is above 3.1, make sure to add the following information at the end of the description: "For those working with V-Ray versions below 3.1, please note that in the materials under the BRDF section, Microfaset GTR (GGX) is used. If your version is older than 3.1, the BRDF field will be empty. Choose between Blinn, Phong, or Ward - whichever you prefer."
If your CORONA version is higher than 1.4: "For Corona render, it is recommended to use a version not lower than 1.5, as the glossiness of the materials is configured with PBR in mind." Separate sections for VRay and Corona renders. If your primary engine is Corona, it's advisable not to use conversion scripts and to create all VRay materials manually. Ensure to thoroughly check each material to avoid any remaining Corona Bitmaps in the VRay material slots.
