1. Workflow Overview

• Purpose:
  Generates high-quality oriental-style female portraits from a reference image, combining image analysis, auto-prompting, multi-stage sampling, and post-processing.

• Core Models:

  • Stable Diffusion (F.1_fp16): Base model for image generation.

  • AWPortrait CN_2.0 LoRA: Fine-tunes for Asian portrait aesthetics.

  • Florence-2-base: Analyzes reference images to generate detailed captions.

  • ControlNet (Implicit): Enhances details via tiled sampling (TTP toolkit).

2. Key Nodes

• Critical Components:

  • Florence2Run: Analyzes reference images and outputs captions.

  • TTP_Image_Tile_Batch: Splits images for high-frequency detail refinement.

  • ImageColorMatch+: Matches color tones to the reference.

  • VAEDecodeTiled: Decodes latent images in tiles to save VRAM.

• Dependencies:

  • Plugins:

    • comfyui-florence2 (for Florence-2 integration).

    • comfyui_ttp_toolset (tiled processing).

  • Models:

    • Download Florence-2-base from HuggingFace.

    • LoRAs: AWPortrait CN_2.0 and XLabs F.1 Realism LoRA_V1.

3. Workflow Structure

• Groups:

  1. Reference Analysis:

     • Input: Reference image.

     • Output: Auto-generated prompts via Florence-2.

  2. Primary Sampling:

     • Input: Prompts, base model, LoRAs.

     • Output: Initial latent image.

  3. TTP Upscaling:

     • Input: Tiled image, high/low-frequency sigma splits.

     • Output: High-res image with enhanced details.

  4. Color Adjustment:

     • Input: Generated image + reference.

     • Output: Final color-matched portrait.

4. Inputs & Outputs

• Inputs:

  • Reference image (e.g., output(1).png).

  • Optional manual prompts.

  • Resolution (default 1024x1024, supports 9:16 portrait).

  • Seed (e.g., 459202764244119).

• Output:

  • Final portrait (via PreviewImage node).

5. Tips & Warnings

• VRAM: ≥12GB GPU recommended; tiling reduces memory usage.

• Installation: Use ComfyUI Manager for Florence-2 and TTP Toolset.

• Debugging:

  • Missing nodes? Check comfyui-layerstyle installation.

  • Color mismatch? Adjust LAB in ImageColorMatch+.
