For professionals working with V-Ray versions below 3.1, **be mindful** of the materials featuring Microfaset GTR (GGX) in the BRDF section. If your version is older than 3.1, the BRDF field will be empty. Choose from Blinn, Phong, or Ward based on your preference. When it comes to Corona render, it's recommended to use a version not lower than 1.5 to leverage the PBR-tailored glossiness settings of the materials.
