Do I have to keep the Chinese characters in the prompt notes?

Yes. Keep the Chinese characters intact as provided in the Note/MarkdownNote. Append any additional image edit instructions after them. Removing or altering them may change conditioning and produce inconsistent results.

Can I use photographed characters or only illustrations?

The workflow is tuned for illustrated characters (it uses an illustration LoRA). You can try photos, but for the best results reduce the illustration LoRA strength and rely more on relight strength to avoid over-stylization.

Why do my results look over-lit or color-shifted?

Lower the relight LoRA strength, refine your appended prompt instructions (e.g., softer key, neutral color temperature), and ensure the environment plate isn’t overly saturated or clipped. Small prompt nudges and balanced LoRA weights usually fix this.

Do I need a cutout with transparency for the character?

A transparent PNG (clean silhouette) gives the best composite. If your source lacks alpha, pre‑mask the character before import to avoid halos or background bleed at the edges.

Relight and Environment Merge - ComfyUI 工作流

这个工作流可将插画角色打光匹配新背景，并融合为统一关键帧。核心功能封装在Subgraph节点（类型ID: 9e3c3756-d15f-4361-8e99-c35673036e68）中，用户只需操作少量输入和参数。通过LoadImage节点分别输入角色图和环境图，用提示词驱动风格（见流程内Note/MarkdownNote），用SaveImage导出结果。

技术上，Subgraph叠加插画LoRA实现风格统一，再用打光LoRA根据环境调整明暗和色彩。子工作流自动处理条件、打光引导和前后景合成，暴露简单的强度滑块和融合选项，便于平衡“风格”与“光效”。流程内Note节点含中文提示词——请保持原文不变，后面可追加英文或其他编辑指令，细化光向、氛围、色温或边缘光。若本地运行，请确保相关文本编码器文件（如qwen_2.5_vl_7b_fp8_scaled.safetensors）已就位，便于子工作流正常编码提示词。

API

通过代码使用此工作流

每个 Comfy 工作流都是一个 JSON 图。下面的内容就是此工作流的完整数据，ComfyUI 运行时也是如此——你可以从该 URL 获取、放入版本控制，或在 ComfyUI 中加载并逐节点运行。

使用 Comfy SDK 从 TypeScript 或 Python 运行。相同代码可用于 Comfy Cloud 或你自托管的 ComfyUI——只需更改基础 URL。

// Install (beta)
npm i @comfyorg/sdk

// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";

const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");

SDK 需要 API 格式的工作流：在 ComfyUI 中打开此工作流，使用文件 → 导出工作流（API）。

Comfy Cloud API 访问需要包含 API 密钥的套餐。
