Pre-rendering using Corona.
The paths to the textures have been reset. The textures have been given individual names. The turbosmooth modifier has been applied to the model (display in the viewport – 0 iterations on the render – 1 iteration). There is no modifier in the OBJ file.

Those who work in a 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 – whichever is preferable for you.
For Corona render it is recommended to install version no lower than 1.5 since the glossiness of the materials is adjusted taking into account PBR.
