The Spinning Ranger Badge: Camera Projection and Simple Texture-Mapping

One of the most successful two hours I spent on the digital effects for Hell is Texas involved two added close-ups on the Ranger Badge, spinning on edge after being discarded. Primarily successful in that it only took me two hours to complete the shot, and a single render to call it done. Plus it enhanced the final slow-motion sequence significantly.

The rotating disk was quickly modelled in Softimage 3D and spun off axis, while rotating. The ground plane is a piece of the wider live-action take (I had failed to shoot any close-ups) projected (via the Camera Projection mental ray shader) onto a curving "cyc" acting as floor and backdrop. Soft shadows and Motion blur are a result of the Mental Ray renderer and two small area lights. Because the scene was so simple, rendering times were very reasonable.
