6. Close the window when complete

Requirements

Core Requirements

• wget must be installed on your system
  • Linux/Mac: Usually pre-installed
  • Windows: Install via chocolatey: choco install wget

For Eye Stabilizer Node

• MediaPipe (for face detection):

  pip install mediapipe==0.10.21
  

  • If not installed, node falls back to basic mode without face tracking

Models Included

The extension downloads the following models:

1. ControlNet Union SDXL - Advanced control model
2. GFPGAN Face Restore - Face restoration model
3. CLIP Vision SDXL - CLIP vision encoder
4. GonzalomoXL Checkpoint - Main checkpoint model
5. IP-Adapter FaceID Plus v2 - Face identity preservation
6. SwinIR 4x Upscaler - Image upscaling model
7. EpiC Negative Embedding - Negative prompt embedding
8. Deep Negative Embedding - Additional negative embedding

Adding More Models

To add more models to the download list, edit model_downloader.py:

MODELS = [
    {
        "url": "https://example.com/model.safetensors",
        "path": "folder/filename.safetensors",
        "name": "Display Name"
    },
    # Add more models here
]

Troubleshooting

wget not found error:

• Install wget on your system
• Linux: sudo apt-get install wget or sudo yum install wget
• Mac: brew install wget
• Windows: choco install wget

Downloads fail:

• Check your internet connection
• Verify the URLs are still valid
• Ensure you have sufficient disk space

Custom Nodes Documentation

Eye Stabilizer

Fixes eye glitching, jittering, and unnatural blinking in video motion transfer workflows.

Full Documentation: EYE_STABILIZER_README.md
Setup Guide: SETUP_EYE_STABILIZER.md

Features:

• Dense eye landmark detection (478 facial points via MediaPipe)
• Temporal smoothing using Kalman filtering
• Blink detection and synthesis
• Eye region enhancement
• Debug visualization

Quick Start:

Video → RMBG → [Eye Stabilizer] → DWPose/Depth → WanVaceToVideo

Test Installation:

python test_eye_stabilizer.py

Character Swap

ControlNet-based character face swapping for pose/scene transfer.

Status: Basic implementation (preprocessors only)
Planned: Full IP-Adapter FaceID integration
