We followed two different approaches with the two models. The Octavia visualizer was done by rotoscoping a live action car and changing the colours in grading plus tracking CGI rims on it. Octavia used a full CGI environment and car only for some shots like the 360° turntable. As the model of the Superb used in the shoot was a pure white one with very washed out reflections we couldn't pull good passes for compositing from it. So we replaced it with a 3d model of the latest version for all shots. A cleanplate was created from the footage and the 3d Superb replaced the filmed one.
Compositing Breakdown:
To have an environment which could reflect in the car we created low resolution proxy geometry carrying pictures of the buildings along the street. The visible backdrop behind the car came from the cleaned footage, everything else was computer generated.
A CAD model of the Superb was tracked onto the footage and rendered in a neutral 50% grey colour with passes for base and coating reflection layers. The final colour variations were created in compositing where the car also met its rims.
