Create a Character Aging Progression Sheet
An aging progression sheet shows the same character at four to six life stages on one page — usually child, teen, adult, middle-aged, elder. The hard part is identity preservation: bone structure, eye shape, and any signature mark (mole, scar, eye color) must survive every step. This guide walks through the locked-seed workflow that keeps the character recognizable from age 8 to age 70 without morphing into a different person at each jump. Answer: Upload a clean adult reference, run 8-angle generation to capture the identity baseline, then re-prompt the front view at each target age (child / teen / adult / middle-aged / elder) with reference strength 0.65–0.75 and the seed locked. Aging beyond ~50 years drifts identity in most diffusion models, so use overlapping age windows and pick the closest match.
- 01
Lock the adult baseline
Generate the standard 8-angle sheet of your adult reference first. This becomes the identity anchor — pick the strongest front-three-quarter view as your aging seed.
- 02
Define your age stops
Decide on 4–6 ages. A clean spread is 8 / 16 / 28 / 45 / 65. Adjacent stops drift less than skipping decades, so add intermediates if you need a smooth timeline.
- 03
Re-prompt each age with the locked seed
Run the front view per age stop, keep the seed identical, and set reference strength to 0.65–0.75 — high enough to hold identity, low enough to let the model alter face structure with age.
- 04
Compare adjacents, not extremes
Drift is invisible between adjacent stops and obvious between extremes. Lay them out child → elder and check that each transition reads as the same person ten years older.
- 05
Patch the drift
If age 45 → 65 reads as a different person, regenerate 65 with the 45 output as reference at 0.8 strength. Build the elder from the middle-aged anchor, not the adult.
- Lock the seed at 12345 (or any fixed integer) and only change the age prompt token between runs
- Reference strength 0.65 is the sweet spot — 0.8+ refuses to age, 0.5 invents a new face
- Signature marks survive better when you describe them ("small scar above right eyebrow") rather than relying on the model to copy them
- Eye color drifts the fastest — re-state it in every age prompt
- Aging past 70 collapses identity in most models; cap at 65 unless you accept a stylized elder pass
- Child stops (under 12) need explicit "child proportions" phrasing or the model returns a small adult
- Hair color and hairline change with age — call them out explicitly per stop or you get teenage hair on a 60-year-old
- Generate two passes per age and pick the closer match before moving to the next stop
