Each model consists of several elements, everything is assembled into one object and 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.

There are no materials in OBJ and FBX files, 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.
