In the scene there are 5 models of black electric ceramic, induction panels, panel widths from 900 mm. Each model consists of several elements, everything is assembled into one object and a multi-material is assigned. All materials have been renamed and simplified as much as possible, I converted the Corona Render materials and did NOT check them in the scene for rendering.

- MIELE KM6669-1 - 942 mm;
- MIELE KM6679-1 - 928 mm;
- MIELE KM6699-1 - 916 mm;
- MIELE KM7697FR - 942 mm;
- MIELE KM7897FL - 936 mm.

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.
