Hello Blender community 
Here is my final render for a Blender 2.90 CGI animation rendered on Cycles: A car chase with an Audi Q7 and a Audi RS4 Police car chasing through the city…
The vehicles come from the add-on “Transportation”: https://blendermarket.com/products/transportation. Cars are imported in Blender with the add-on, uv unwraped in Blender and textured in Substance Painter.
I use the RIGACAR add-on by digiCreatures for all the vehicles of this shot: https://www.youtube.com/watch?v=D3XQxA_-TzY
The vehicles, that compose the traffic, are animated with the same curve that create the road. All assets are high-poly but managed with an instance system. In that way, it’s possible to duplicate each vehicle many times, without overloading the scene in Blender. I added a random color gradient on the shader car paint of each vehicle, which allows to obtain a new color when I duplicate the car.
The building comes from the Metropolitan pack by videoCopilot: https://www.videocopilot.net/products/3d/metropolitan/

This project was carried out over two weeks, during my free time. I had to make compromises especially on the compositing.
