ComfyUI_HunyuanPortrait Node Pack

This node pack integrates the Tencent HunyuanPortrait framework into ComfyUI. It allows users to generate portrait animations driven by a video, using a source image for appearance.

Features

• Simplified Model Loading: Uses a single folder input for main models and a dropdown for VAE selection.
• Local Model Loading: All models are loaded from local paths. No automatic HuggingFace Hub downloads by the nodes.
• Portrait Animation: Generates videos based on a source portrait image and a driving video.
• Customizable Preprocessing & Generation: Offers various parameters to control the preprocessing and video generation stages.

Setup

Clone or download this repository.

Download Models

You need to download the model weights from the official HunyuanPortrait sources.

• HunyuanPortrait Models:

  • Go to the HunyuanPortrait Huggingface repository.

  • You need all the models downloaded into ComfyUI/models/HunyuanPortrait/hyportrait

  • unet.pth, dino.pth, expression.pth, headpose.pth, image_proj.pth, motion_proj.pth, pose_guider.pth

    • arcface.onnx downloaded to ComfyUI/models/HunyuanPortrait from https://huggingface.co/FoivosPar/Arc2Face/resolve/da2f1e9aa3954dad093213acfc9ae75a68da6ffd/arcface.onnx
    • yoloface_v5m.pt downloaded to ComfyUI/models/HunyuanPortrait from https://huggingface.co/LeonJoe13/Sonic/resolve/main/yoloface_v5m.pt

• VAE Model:

  • The HunyuanPortrait project uses a Stable Video Diffusion VAE. A common one is stabilityai/stable-video-diffusion-img2vid-xt's VAE.
  • You can download it from Hugging Face: stabilityai/stable-video-diffusion-img2vid-xt - vae/diffusion_pytorch_model.fp16.safetensors

Organize Models (Crucial Step)

Organize the downloaded files as follows:

1. Create a main directory for HunyuanPortrait models within your ComfyUI models folder: ComfyUI/models/HunyuanPortrait/

2. Inside ComfyUI/models/HunyuanPortrait/, place:

   • The entire hyportrait folder (which you downloaded, containing the various .pth files).
   • arcface.onnx
   • yoloface_v5m.pt

3. Place the VAE model (e.g., diffusion_pytorch_model.fp16.safetensors) in your standard ComfyUI VAE directory: ComfyUI/models/vae/ (e.g., ComfyUI/models/vae/diffusion_pytorch_model.fp16.safetensors)

The final structure should look like this:

ComfyUI/
└── models/
	├── HunyuanPortrait/ <-- This is your 'model_folder' for the node
	│ ├── arcface.onnx
	│ ├── yoloface_v5m.pt
	│ └── hyportrait/ <-- folder containing dino.pth, unet.pth, etc.
	│   ├── dino.pth
	│   ├── expression.pth
	│   ├── headpose.pth
	│   ├── image_proj.pth
	│   ├── motion_proj.pth
	│   ├── pose_guider.pth
	│   └── unet.pth
	└── vae/
	  └── diffusion_pytorch_model.fp16.safetensors <-- Or your chosen VAE file

How to Use

1. Load HunyuanPortrait Models:

   • Add the Load HunyuanPortrait Models node (found under the HunyuanPortrait category).
   • Model Folder: Set this to your main HunyuanPortrait weights directory (e.g., ComfyUI/models/HunyuanPortrait).
   • VAE Name: Select the correct VAE file (e.g., diffusion_pytorch_model.fp16.safetensors) from the dropdown.

2. Load Inputs:

   • Use a LoadImage node for the source portrait image.
   • Use a LoadVideo (VHS) node or similar to load your driving video frames.

3. Preprocess Data:

   • Add the HunyuanPortrait Preprocessor node.
   • Connect hunyuan_models from the Load HunyuanPortrait Models node.
   • Connect the source_image from your LoadImage node.
   • Connect the driving_video_frames from your video loading node.
   • Set driving_video_fps to match the actual FPS of your input driving video.
   • Adjust other preprocessing parameters like limit_frames and output_crop_size as needed.

4. Generate Video:

   • Add the HunyuanPortrait Generator node.
   • Connect hunyuan_models from the Load HunyuanPortrait Models node.
   • Connect preprocessed_data from the HunyuanPortrait Preprocessor node.
   • Connect driving_data output from the HunyuanPortrait Preprocessor to the driving_data input of the HunyuanPortrait Generator. This carries information about the temporary video file for cleanup.
   • Adjust generation parameters such as height, width, num_inference_steps, fps_generation (FPS of the output video), guidance scales, etc.

5. Preview/Save Output:

   • Connect the IMAGE output of the HunyuanPortrait Generator to a PreviewImage node to see individual generated frames.
   • Alternatively, connect it to a VideoCombine (VHS) node to assemble the frames into a video file (e.g., MP4, GIF). Ensure the frame_rate in VideoCombine matches your fps_generation setting in the Generator for correct playback speed.

Notes

• Use a color match node to restore color levels as outputs are messy
• Dependency Version: It is crucial to use diffusers==0.29.0 as specified in requirements.txt. Newer versions of diffusers may have breaking API changes that are incompatible with the vendored code in this node pack.
