This is a modern architecture design rendered using Cycles in blender 3.0. I have provided you with different natural light setup to have a better view of it's textures. The design is satisfying. The OBJ file has been exported from blender itself. In case in need of any other file format I can help provide it.
This file does not have any type of protection. You can reuse the scene, the render settings, the lights, the materials, but above all you can learn from the file, moving inside the project, observing how the light was created and handled, how materials are developed, what is the role that every textures play within them, and the values that fill every single option.
