For those working with V-Ray versions below 3.1, pay attention to the materials in the BRDF section. Featuring Microfaset GTR (GGX), **_V-Ray Compatible 3.1+ Materials_** provides a seamless integration for your 3D projects. If your version is older than 3.1, you might encounter an empty BRDF field. In such cases, you can opt for alternatives like Blinn, Phong, or Ward based on your preference.
