“Once” is an interactive virtual reality narration film based on post-war experience, which is set after a continuous war period between two countries. Current virtual reality creations about warfare have only been describing the war itself, and its expression easily causes the audience’s lack of social empathy, which results in weakening the portray of anti-war consciousness. More importantly, this kind of creation just narrates in one single view of angle and performs imperfectly. Due to those issues, through the three-identity switching, subtitled guidance and stylized visualization, we create this VR narrative film, which uses the image of common people after the war as clues to express the trauma it brings.

In my junior year of undergraduate, Lutong Li and I designed ONCE with Unity and HTC VIVE, which was my first VR work. Such co-design on VR works in my undergraduate years greatly encouraged me to embark on a journey to explore virtuality and reality in greater detail.
