This award is to honor the achievement of visual effects created through simulation in an animated feature motion picture.  The award is for a body of work, and all simulated effects in the project will be considered.  Simulated effects are dynamic effects that generally include particle, dynamic, fluid, cloth, hair, and crowd simulations. The effects may interact with, or be elements that make up, the characters, set elements and environments with which they coexist.  The Before & Afters must demonstrate the simulation processes used to create the effects presented for consideration.
