Before production begins, it is important to prepare a clear and well-organized package of project documentation for the visualization team. The most useful materials typically include drawings, BIM or 3D models, reference images, material information, project descriptions, and examples of the desired visual mood.
Additional notes about specific design intentions, atmosphere, or presentation priorities can also be extremely valuable, although they are not always required. The clearer the project goals and expectations are from the outset, the more efficiently the visualization process can move forward and the more accurately the final images will reflect the architect's original vision.
