There are 5 models in the scene.
– oven H7860BPX 600 mm in white;
– oven with microwave H7840BPX 600 mm in white;
– hob KM 7474 FR 800 mm;
– refrigerator MIELE KFN29683D white glass;
– Island hood MIELE 6698D 898 mm – white.

Each model consists of several elements everything is assembled into one object and a multi-material is assigned. All materials were renamed and simplified as much as possible I converted the Corona Render materials and did NOT check them in the scene for rendering check the model in a separate scene.

The FBX file contains all the models with materials. There are no materials in the OBJ file only geometry.

Who works in V-Ray version lower than 3.1 be careful in the materials in the BRDF section there is Microfaset GTR (GGX) if your version is older than 3.1 then the BRDF field will be empty. Choose Blinn Phong or Ward – which is preferable for you.
