There are four models in the scene, the MIELE H7860BPX oven in three colors, black, white and graphite, as well as one 550 mm wide hob electric ceramic panel MIELE KM 6017. Inside each oven there is a separate model of a finished round loaf of bread, which I myself scanned. The bread model is a separate object, has a Turbosmooth modifier (0/1). The model of each oven together with a loaf of bread is grouped and has the prefix [G] _ in the name, also in the group each oven has 3 light sources. The oven consists of many elements, everything is assembled into one object and multimaterial is assigned. All materials were renamed and simplified as much as possible, I converted Corona Render materials and then adjusted them in the scene for rendering. In the FBX file there are all models with materials, but there are no light sources, add them yourself. There are no materials or light sources 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.
