This ComfyUI workflow is designed to seamlessly integrate a product image into a background scene and apply realistic relighting using advanced AI techniques. The workflow begins by loading your product and background images using the LoadImage node. Then, it utilizes the RegexReplace node to prepare the images for compositing. The core of the workflow is the ByteDanceSeedreamNode, which leverages the Seedream 4.5 model to intelligently relight the combined images, ensuring that the lighting and shadows are consistent and natural. This technique is particularly useful for creating professional-quality product images without the need for complex photo shoots or manual editing. By automating the compositing and relighting process, this workflow saves time and enhances the visual appeal of product images.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// Install (beta)
npm i @comfyorg/sdk
// Run "Composite your Product + Scene and Relight" (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
// This workflow, exported in API format (see note below)
const wf = await client.workflows.fromFile("templates-product_scene_relight_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("1", "image", asset); // LoadImage
const job = await client.run(wf);
await job.getOutputs("23")[0].toFile("output.png"); // SaveImageThe SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
