...and the breakdown of the UFO shot.
After scouting the streets of San Francisco, I finally found a building that had a top shaped like a UFO or saucer. I immediately filmed the background plate in San Francisco downtown, around kearny and post st. It was right at the twilight hour so I was able to get some nice lighting and highlights at least at the top of the buildings. I tracked the entire scene using PFTrack, which took a bit of time actually. Then I brought everything back into Maya and modeled, textured, lit, and animated the UFO. The final composite was done in Shake. I touched up a few frames with photoshop and after effects.
