Objects and materials in the scene have logical names.
"For Corona Render, it is recommended to use a version of at least 1.5, as the glossiness of the materials is set with PBR in mind.
If you are working in V-ray version lower than 3.1, please be careful. In the materials section, the BRDF is set to Microfacet GTR (GGX); if your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong, or Ward - whichever is preferable for you."
