Hello, I have been working in the field of 3D visualization for five years, the process of visualization is to create a modeling job as the initial presentation, and then provide the material and the placement of the lamp so that the end point of the process of rendering or view camera. I apply the process in the interior or exterior scene, just a set of materials which would you choose and polished in your scene. If you are in doubt, be able to see a sample file in 3d modeling of all interior and exterior, thank you
