La Colemba collaborated on the creation of the film’s river sequences by developing physically accurate CG water environments built around the unique geography of steep cliffs and mountain streams. Rather than creating water simulations in isolation, our team designed an integrated 3D environment that provided the physical conditions necessary to generate the specific water behavior required by the director. Beyond the river itself, we enriched the surrounding environment with natural elements that enhanced realism and allowed the interaction between the character and the landscape to feel authentic, supporting both the narrative and the emotional rhythm of the sequence.
