The problem

Prompt-only generations

distort product shape and

shift tone between outputs.

The move

A standardized 3D stage

the generator builds on —

product shape locked.

Controlling the input,

not the prompt.

LG H&H produces marketing imagery for dozens of beauty brands at a volume traditional photography can't match. Generative AI was the obvious solution, but prompt-only workflows produced inconsistent product shapes and brand tones across outputs.

The fix was to move control upstream. The team built a library of 3D product assets and standardized Substance 3D stages — scene, lighting, camera — so the generator only fills in background and mood. Product fidelity stays consistent across runs.

Method, not

toolchain.

With inputs standardized, the team's work shifts from prompt engineering to curation — writing segment briefs, reviewing generated frames, and making art direction calls on skin, styling, and mood.

The pipeline was documented in an internal handbook for marketers without ComfyUI experience. The method is the deliverable; the specific generator behind it is replaceable.

ComfyUI

Base generation with segment parameters — ethnicity, age, lifestyle, values. The 3D stage defines the frame; the model generates around it.

Tool — ComfyUI / Stable Diffusion

02

Photoshop

Manual adjustments to skin, expression, hair, wardrobe, and accessories. Art direction is applied at this step.

Tool — Adobe Photoshop

KREA Enhancer

Realism pass. Removes the plastic-skin texture typical of AI outputs and restores photographic surface detail.

Tool — KREA AI

A UI layer over

the pipeline.

Marketers at LG H&H aren't generative-AI specialists, so opening ComfyUI directly wasn't a realistic handoff. The pipeline needed a UI that matched how marketing teams already work.

The Archiving site is that layer — a library of AI models filtered by ethnicity, age, lifestyle, and values, with a request form that maps a standard brand brief ("Dr.Groot 제이몬스터즈, Saturday morning, parent with teen") to pipeline parameters.

Takeaways.

Prompts describe intent but don't enforce it. A standardized 3D stage, a shared model library, and a documented handbook do — they specify camera, lighting, and the steps the team has used before. Output becomes predictable across runs.

Moving control from prompt to input was what made the pipeline reproducible across the team, not just for the people who built it.
