Product Placement (Flux.2 Klein)
Drop in up to 3 product shots and a reference composition, and this workflow places your products into the scene with accurate label text, packaging detail, and lighting that matches the reference. Fully open source stack: Qwen3-VL reads your inputs and writes the edit prompt, Flux.2 Klein 9B handles the multi-image composite, and LTX-2.3 animates the final placement into a product spot. Batch concatenation and auto-scaling keep inputs sharp at any resolution. Runs on Comfy Cloud out of the box, or locally on your own hardware. No closed APIs.

概要
This ComfyUI workflow automates realistic product placement using an open-source stack. You provide up to three product shots plus a reference composition, and the graph places the products into the scene with text-aware detail and lighting that follows the reference. A Qwen3-VL stage inspects your inputs and writes a context-rich edit prompt, Flux.2 Klein 9B performs the multi-image composite, and LTX-2.3 turns the final still into a short, polished product spot. Core utility nodes like LoadImage, PreviewImage, PreviewAny, BatchImagesNode, StringConcatenate, and SaveVideo make it easy to iterate and export.
Technically, the product and reference images are loaded, batched, and auto-scaled so Flux.2 Klein receives sharp, consistent inputs regardless of your source resolution. The prompt is assembled by Qwen3-VL (guided via StringConcatenate) and passed into the Flux.2 sampler to condition placement, label fidelity, and scene lighting.
After the composite is approved in PreviewImage/PreviewAny, LTX-2.3 generates a short motion segment from the final placement and SaveVideo writes the result to disk. The custom inference nodes (461b058e-342d-497e-aac1-a5fb6551e33a, fdd45ff8-8dff-43e8-b2c0-2d26053388b8, 6dbca6ef-ca4b-4af8-a99b-b834745f3a9b, 5c2c98c8-2e8f-47ca-9403-686e35a5ef94, 04e3b3b1-a711-485c-be05-f59f9507bd4e, ffacbfba-7659-45df-a3b8-7560f4800088) encapsulate the model runners and scaling/conditioning logic so you can run fully locally or on Comfy Cloud—no closed APIs.

# run() also passes api_key to the partner nodes in this workflow.
job = client.run(workflow, api_key=api_key)よくある質問
No. The workflow supports 1–3 products. Leave unused LoadImage nodes empty; the BatchImagesNode will process only the images you provide.
Use high-resolution product shots (ideally with clean, front-facing labels) and transparent PNGs if possible. Keep the reference image close to your target output resolution. If text or edges look soft, increase input resolution, refine the Qwen3-VL prompt via StringConcatenate, or reduce the final output size.
Yes. All stages run locally with open models (Qwen3-VL, Flux.2 Klein 9B, LTX-2.3) through the custom inference nodes (e.g., 461b058e…, fdd45ff8…, 6dbca6ef…, 5c2c98c8…, 04e3b3b1…, ffacbfba…). Ensure you have the model weights installed and paths set in the node settings.
Lower the working resolution, shorten the LTX-2.3 duration, or disable any unused image slots. You can also run the composite first at a smaller size, lock a good seed, then upscale for a final pass if your hardware allows.
