‘Mouse’ exhorts the irresistible flavour of Kerry’s low fat cheese with an acrobatic super stunt mouse defying thousands of mouse traps. MPC’s proprietary tools played a vital role in the successful development of the spot and the Nuke Compositing system brought it all together.MPC's 3D team animated the hero character retaining a realistic look for the first part of the commercial before his transformation to stunt mouse for the second half. All of this whilst retaining the realism of the piece. Maya was used for animation with in-house tool ‘Furtility’ grooming the fur and Renderman and Tickle for the rendering.One of the main challenges was animating the thousands and thousands of CG mouse traps seen snapping and colliding with each other in each shot. To achieve this physics-based ‘domino effect,’ a series of event based simulation scripts were written to automate the traps snapping behaviour based on incoming collisions. The 2D team worked with Nuke which allowed them to composite the 3D heavy shots in a time efficient way. With the directors wanting control over all camera moves in post, Nuke was fundamental, enabling the virtual 2D camera moves which zoom right into the mouse.
