For those working with *V-Ray* versions older than 3.1, **3ds Max** model materials containing Microfaset GTR (GGX) in the BRDF section may need attention. If your version is 3.1 or newer, the BRDF field will be empty. Choose from Blinn, Phong, or Ward for your preferred selection.
When using *V-Ray* for your **3d** interior decor projects, be mindful of the BRDF options for **3D room design**. Ensure seamless integration of materials for your **3dsky** designs by selecting the appropriate BRDF settings based on your **3d design** software version.
