In the scene, a model of a mortise hood made of polished stainless steel MIELE DA 2808 900 mm, hood width 884 mm, depth 474 mm. The model consists of several elements, everything is assembled into one object and multimaterial is assigned. All materials are renamed and simplified as much as possible, I converted the materials of Corona Render and did NOT check in the scene for rendering, check the model in a separate scene.

There are no materials in the OBJ file, only geometry.

Who works in the 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.
