Now I created materials for all entities in scene. The most tricky part on this, was create realisitc corten facade.
Then I setup render settings (samples, exposure, color managmnet, …) and render the scene.

First, I made some research on internet about the building. Looked on a lot of photos, building plans and try to get better knowelage of this project. Before I place a camera, some geometry fixing was needed after import to blender. Then I paced a camera to position which work best for me. For picture size I choose a traditional photo format 15x10cm. Last thing I did in prepared work was lighting the scene. I didint want nice blue suny sky, with sharp, contrast and dynamic shadows. I see this all the time in visualization and I think this is not the most common wheater for northen Europe. Thas the reason, I made mornig overcast sky with very soft and light shadows.
