Compositing

Here are some of the passes used to render the final shots.

Motion Vector pass

 

Ambient Occlusion pass

 

CG Smoke

 

CG Particles

 

The original plate was shot on a moving car at 60km/h with a shutter speed of 1/50 which does not gives a nice motion blur. However, that's the speed limit in Singapore, so can't do much.

 

 

 

The footage was sped up 400% so it's equivalent to about 240km/h footage and with added motion blur, it's pretty much looks like shot on a high speed vehicle.

 



And here's the final composite. An animated HDRI was used for the environment lights to gives the moving reflection on the car surface.

Similar techniques were used for other shots.
