All objects in the scene are logically named grouped and have your Multi-sub material. The model is created for anti-aliasing so that you can control the density of the mesh for a particular frame. All files without anti-aliasing – add as you see fit.

For Corona render it is recommended to install at least version 1.5 as the glossiness of the materials is adjusted with PBR in mind.
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.
