When tasked with visually translating the suffocating feeling of university burnout for Spritzer Ion, we stepped in to lead the FX simulation and VFX integration. The core challenge was orchestrating a complex rigid body simulation of thousands of CG school supplies — exam papers, books, laptops, and stationery — relentlessly dropping, colliding, and piling up around the live-action student. By implementing meticulous 3D lighting and shading, we ensured these digital props integrated flawlessly with the practical set and the physical talent. To contrast this overwhelming chaos, we also art-directed and rendered the crisp consumption scenes, crafting refreshing, bubbly CG liquid environments that highlight the isotonic product's thirst-quenching appeal.
