First we "build" the virtual model of the building which can be cut in any direction.

In the second stage we do white model-like visualizations to experiment with lighting.

After it, we assign the textures. This might change the lighting environment, so we have to follow it by re-adjusting the lights.

In the next stage we finalize the lighting, the shadows and direct lights.

After this is done, we start to "dress up" the rendered picture by putting people, plants, trees and extra objects in the scene. These small details make fill the final picture with life, and make the viewer feel the space itself.

And finally we do graphical post-processing. We do little corrections and some special effects if needed.
