We created this spot for an extensive COD campaign at The Mill . The spot included a vast amount of work ranging from live-action integration to the creation of simulated armies in CG.
A key element in the spot was the recreation/destruction of the foreground housing complex in the final shot below.
As this was the final shot, everything had to be tied together, armies, robots, ships, explosions, etc., all situated behind the foreground housing complex transitioning from live-action to the game world.
