Mirror of Vengeance is a 3D animated short film with a runtime of approximately 2 minutes and 40 seconds. The story explores psychological horror through themes of identity, repression, and emotional fragmentation. It follows a timid schoolgirl whose suppressed emotions manifest as a vengeful mirror double, ultimately leading to her entrapment within the mirror world. A key challenge of the project was translating the visual language of Japanese horror manga into a 3D environment while maintaining emotional subtlety. From a technical perspective, the film experiments with a hybrid workflow combining Maya for animation and Unreal Engine 5 for real-time lighting, rendering, and cinematic composition.
