The biggest challenge was to integrate the different homes she passes and the different lighting situations from day to night into the overall structure of the key visual – to have a coherent architectural impression in the end without compromising on realism and plausibility. Atmospheric elements like 2D and 3D clouds and volumetric lights complemented the composition. To support the architectural perception of the total structure, there were shots in which real images were combined with CGI elements and visual effects as well as completely artificial generated sets.
