Process

Static vs Zooming-In Cameras


Low vs High Render Samples Research


Compositing & AI-Upscaling Research (no AI in final renders)


Visual Development
Alongside recursive growth as the key concept, other organic morphism like pyro simulation with deliberate preservation of mushroom shapes and  plant growth (L-system) were explored for the film’s merging with nature and the search for sense of belonging.
