there's something tender about a project that starts as one thing and becomes something else entirely. something you didn't know you needed to make until you were already making it.
daughter of the inner stars was never supposed to move.
it was conceived by composer nicholas buc, writer and director james vinson, and producer melanie hiluta as a static 2d picture-book-style concert experience — something gentle and still, meant to introduce children to the world of symphony music. fifty minutes of orchestral feeling, wrapped in illustration. quiet. beautiful. enough.
but then the scope began to breathe.
production designer nathan su, founder of inferstudio — an architecture and design firm, not a film studio, which feels important somehow — was brought on board. he started asking what it might look like to pull those 2d illustrations into three dimensions. character artist ludvig holmen sculpted the characters as full 3d meshes. the young girl at the heart of the story, fia, began to take shape in space rather than on a flat page.
and then, in 2023, something small happened that changed everything.
holmen performed a range-of-motion study. not in a professional capture volume. not in a suit covered in reflective markers. on a phone. the footage was uploaded into autodesk flow studio, a web-based, ai-powered motion capture workflow tool. the system composited the character back into the scene and translated holmen's movements onto her with a reported accuracy that the team described as the first real indication that fully animated sequences might actually be within reach.
fia didn't even have her final face or hair yet. it was a rough, incomplete version of her. and still, she moved.
flow studio works without a motion capture suit. that detail keeps sitting with me. there's something almost democratic about it — the idea that the barrier between stillness and motion could be a phone and an internet connection.
approximately eighteen months before the sydney premiere, the team had identified both autodesk flow studio and unreal engine metahuman animator as the technologies that could carry the project forward. animation technical director nour hassoun worked with and refined the motion-capture data coming out of flow studio. the team tested facial animation, render styles, frame rates, texturing techniques. the ukraine-based studio tubik, who had developed the film's fantastical characters, remained woven into the fabric of it all.
the team estimates that flow studio reduced their animation times by 80%. that number is their own estimate, not independently verified, but even as an approximation it suggests something significant about what this kind of tool makes possible for a production that was never resourced like a major studio film.
the film premiered with the sydney symphony orchestra at the sydney opera house in 2024. in 2025, it made its north american debut with the vancouver symphony orchestra. live narration, live orchestral performance, original animation — all of it together.
something that began as a picture book, performed in concert halls.
the team has said they never imagined the resulting production could be possible when they first embarked on the project. i believe them. and i think that's the part that moves me most — not the technology itself, but the way it arrived quietly, through a phone camera and a character without a face yet, and whispered: keep going. this might be possible after all.
fia moved. and so did everything else.
