For Corona render, it is recommended to use version no lower than 1.5, as the glossiness of materials is set with PBR in mind.

If you are working in V-Ray version lower than 3.1, be careful, the materials in the BRDF section are set to Microfaset GTR (GGX), if your version is older, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.
