"In one challenging shot, where two moons collide, the team used Fracture FX, a new fracturing plugin for Maya. This allowed them to create a procedural animation which replicated the break up of a planet into hundreds of thousands of pieces in a way that a real planet would crack and break up under stress from another planet impacting on it. They could also add gravitational forces or speeds of impact which further enhanced the realism of the rendition of the event."
