The hardest part of AI campaign work isn't making one good frame. It's making the same person appear in the next one. I built a campaign character, locked her identity, and ran her across three unrelated products.
Front, three-quarter, side, back. Scale sheet, head detail, colour palette, wardrobe, props, behaviour notes. Before a single campaign frame exists, the model does - as a spec, not a lucky generation. Every frame in this campaign references her.
