These mock-ups show the creation of rudimentary 3d worlds that we can position to match camera and track the camera if needed. Gives Production some leeway if a moving shot is desired. The general concept is to emulate different styles of video games over the years. With this mock-up style, the Interviewee is left in a more realistic rendering. Filtered light areas in the environment will also have more realistic and cleaner lines, whereas shadows will fall off into the game rendering, such as 8-bit visual style.
For rendering on interviewee legs:
A layer of FX could be added to transition wide shots of interviewee into the 8-bit world on their legs and feet, as a way to connect them with the environment.
