Four product scenes in one FLUX.1 schnell run

- FLUX.1 schnell product scenes - Six marketplace crops ## Why run four at once

A single scene composite is good for testing one direction. In a real listing, operators usually need several scenes for the same product. Four separate runs let product size, placement and shadow direction drift; the set starts to look like four different products.

This workflow puts four prompts in one job and shares the product matte, position and shadow. The model generates four backdrops; product pixels always come from the same PNG.

How to pair the four prompts

Prefer one key-light direction across all four, changing only surface and environment:

1. 1White marble + window light from the left
2. 2Warm wood + window light from the left
3. 3Beige linen + window light from the left
4. 4Dark stone + window light from the left

If one says “window light from the left” and another says “hard top light”, the product looks relit in each frame and the set falls apart.

On the store, those four prompts are built in and there is nothing to type; the recipes below are for editing the downloaded bundle or running the graph yourself in ComfyUI.

Node structure

• One set of FLUX.1-schnell loaders (UNET, CLIP, VAE)
• Four CLIPTextEncode nodes, one per scene
• Four KSampler nodes sharing the model, different seeds
• Four VAEDecode → four composite chains
• One product matte, repeated four times
• Batch SaveImage with scene numbers

The four branches share model loading, so VRAM is not multiplied. That is why it is more stable than four separate runs.

Output and selection

One job returns four 1024×1024 images. Judge the set, not a single frame:

• Is product scale consistent?
• Is shadow direction consistent?
• Do the four images share one color temperature?
• Does any product edge have a white fringe?

If one frame fails, rerun only that prompt. Do not rerun the whole set and burn credits.

Cost and limits

Four branches in one job cost roughly 2–3× the GPU time of one scene, but far less cold-start and scheduling overhead than four separate jobs.

It is not a queue manager: 20 products still mean 20 jobs. True batch scheduling, retries and a progress dashboard are a later product.

Next step

After the set passes, run the crop workflow for marketplace sizes. Do not crop inside each scene, or the margins will diverge.

Four prompt recipes that stay consistent

The prompts below share one key light from the left. Replace the surface and the background, not the light:

1. 1white marble tabletop, soft window light from the left, neutral studio wall, shallow depth of field, no product
2. 2warm oak counter, soft window light from the left, blurred kitchen shelves, shallow depth of field, no product
3. 3beige linen tabletop, soft window light from the left, quiet neutral wall, shallow depth of field, no product
4. 4dark grey stone slab, soft window light from the left, moody grey wall, shallow depth of field, no product

Keep “no product, no text” in every prompt. Without it, FLUX may draw a second object or a label, which fights the composited product.

How to QC the four-image set

Open the contact sheet at 50% and scan in this order:

• Silhouette: the product must have the same outline in all four frames.
• Scale: the product should occupy roughly the same share of the canvas.
• Contact: the shadow should touch the base, not float below it.
• Color: the four frames should feel like one shoot, not four stock photos.
• Text: if the product has packaging, zoom to 100% and check that no letter has been softened.

If one frame fails, note the failed prompt and rerun only that branch. A full rerun changes all four seeds and makes comparison harder.

What to do when one prompt fails repeatedly

A single prompt that consistently clips the product or produces a busy background is usually too vague. Add a surface, a light direction and a depth cue. If it still fails, replace that scene with a simpler surface; four coherent frames beat four ambitious ones.
