This image demonstrates how a 3D rendered model of a 1957 Chevy can be placed "inside" a scanned photograph of a field. To accomplish this feat an invisible polygon was added under the car and the 3D scene oriented to match the same perspective view of the background image. Shadows from the car were then cast onto this invisible polygon and used to darken the background image (this is NuGraf's "cast shadows on background" material option). These shadows "tie the car down" to the ground and make it appear to be part of the background image.

To match the lighting of the background image, and to create some nice highlights on the car, 6 light sources were added to the scene with 2 of them casting shadows.

The 1957 Chevy model uses a bronze metallic shader for the main body color and a spherical reflection map for the chrome.
