3ds Max: Create Blurred Car Lights

to create bleievable night city visualization, we need to follow some rules of photography. One of them is maitaining "realistic" shutter speed. In the night, when there is small amount of light, we make photos with longer exposure times to avoid noisy images. One side-effect of this is that every moving light source becomes blurred. It is the most prominent effect when shooting night streets - red and white car lights become smudges. How can we create such effect in our visualizations? Some artists use Photoshop layers for that, but if you want to truly control direction of moving lights and their effect, you can use 3ds Max for that.
