The world-building relied on a complex integrated AI workflow developed by Pineapple VFX Creative Director & Founder Kia Coates and AI & CG Lead Mark Bailey, in close collaboration with Daniel and his production team. Welsh landscapes were geo-mapped into 3D terrain, then layered with AI-generated woollen landscape renders projected directly onto the geometry. This gave the VFX artists a flexible way to explore scale, texture, and composition in three dimensions before committing to final shots.

The same philosophy carried through to the interiors, combining real TFW carriages with in-camera puppets based on real people, keeping the work grounded while maintaining its surreal tone.
