Singles are luck; series are craft. A follower returns for a person, and a person is a set of details that do not drift. This is the studio method for holding one fictional muse steady across twelve frames and four tools.
Write the character sheet first
Before the first render, fix the muse on paper: name, age (state it in the brief every time), hair, two facial anchors, build, and one signature — a necklace, a beauty mark, a way the hair is always worn. Save the exact paragraph. Every prompt in the series begins with that paragraph pasted unchanged; you are allowed to be bored by it. Boredom is what consistency feels like from inside.
Shoot in a deliberate order
Frames one to three: establish her — the canonical portrait, the signature look, the room she belongs to. These become your reference set. Frames four to eight: vary one axis at a time — new outfits, then new rooms, then new light — checking each against the reference set before continuing. Frames nine to twelve: the adventurous ones, an animation, a face-swap recast of a drift, an upscale of the opener. By then the series has a centre of gravity that pulls strays back.
Repair drift at the right bench
When a frame’s face wanders from the sheet, do not re-render the set: recast that frame at the face swap bench from the canonical portrait. When a prop changes colour between frames, the editor fixes it for less than a render. Reserve the generator for new material; consistency maintenance is cheaper at the repair benches.
Keep a one-line log
Frame number, what varied, what to fix. Twelve lines, written while you work. The log is how the next series starts at frame twelve quality instead of frame one.
