For this project I wanted to simulate light fog coming through window blinds. As the camera moves I wanted to see changes to the light moving through the fog.
To add depth of field, I needed to render out a Z-depth channel. After that, in Shake, I blurred the image based on the Z-depth information.
Adding Light Fog.

The occlusion is then added to get the contact shadows.
