1. Workflow Overview

• Purpose:
  Named "A Rui - Product Migration_Background Swap_Clothing Swap_Redux+ACE++", this workflow is designed for product image editing, including:

  • Background Replacement: Migrate white-background product images to new scenes.

  • Clothing Swap: Modify apparel via masking and inpainting.

  • Advanced Control: Combines Redux (fine-grained redraw control) and ACE++ (stylization LoRA).

• Core Models:

  • Stable Diffusion Inpaint (F.1-Fill-fp16_Inpaint&Outpaint_1.0): For local redrawing.

  • ACE++ LoRA: Enhances details and stylization.

  • ReduxAdvanced Node: Precision control over redraw areas.

2. Key Components

Critical Nodes:

1. LoadImage:

   • Loads product (white background) and background images (requires manual mask).

2. ImageResizeKJ:

   • Resizes images to 1200x1600 (Lanczos interpolation).

3. Joy_caption_two:

   • Uses Meta-Llama-3 to generate text prompts from images.

   • Plugin: comfyui_slk_joy_caption_two.

4. ReduxAdvanced:

   • Controls redraw conditions (e.g., area, keep aspect ratio).

   • Plugin: ComfyUI_AdvancedRefluxControl.

5. KSampler:

   • Sampler: euler, 30 steps, CFG=1.

Dependencies:

• ACE++ LoRA: Download and place in models/loras/.

• ReduxAdvanced Plugin: Install via ComfyUI Manager or GitHub.

3. Workflow Structure

Groups:

1. Global Input:

   • Loads models (UNETLoader), VAE, and CLIP.

2. Captioning:

   • Generates prompts via Joy_caption_two.

3. Core FILL+Redux:

   • Combines InpaintModelConditioning and ReduxAdvanced.

4. Image Merge & Crop:

   • Merges images (ImageConcanate) and crops target areas (Image Crop Location).

4. Inputs & Outputs

• Inputs:

  • Images: Product (white bg) + background (masked).

  • Text: Auto-generated or manual prompts.

  • Params: Resolution 1200x1600, seed randomize.

• Output:

  • Final composite image (saved via SaveImage).

5. Tips & Warnings

• VRAM: ≥8GB GPU recommended; use --medvram for high-res.

• Plugins: Ensure comfyui_layerstyle and comfyui-kjnodes are installed.

• Mask Precision: Manual masks must cover edges to avoid artifacts.
