ComfyUI HunyuanWorld Node Pack

A comprehensive ComfyUI node pack for HunyuanWorld offering text-to-panorama generation, 3D world reconstruction, and related utilities directly within ComfyUI.

🔧 Development Status: Offline Mode In Progress

This node pack aims for complete offline operation but currently requires additional configuration development. For immediate offline panorama generation, use the recommended workaround below.

Requirements

• ComfyUI (latest)
• Python 3.x
• CUDA-enabled GPU (for accelerated models)
• Dependencies: see requirements.txt

Installation

Automatic Installation (Recommended)

1. Clone this repository into your ComfyUI custom_nodes directory:

   cd C:\ComfyUI\custom_nodes
   git clone https://github.com/cedarconnor/ComfyUI_HunyuanWorld.git
   

2. Install all dependencies with a single command:

   cd C:\ComfyUI\custom_nodes\ComfyUI_HunyuanWorld
   C:\ComfyUI\.venv\Scripts\python.exe -m pip install -r requirements.txt
   C:\ComfyUI\.venv\Scripts\python.exe install.py
   

3. Place model files:

   • FLUX Base Models → C:\ComfyUI\models\unet\
     • flux1-dev-fp8.safetensors
     • flux1-fill-dev.safetensors
   • HunyuanWorld Models → C:\ComfyUI\models\Hunyuan_World\
     • HunyuanWorld-PanoDiT-Text.safetensors
     • HunyuanWorld-PanoDiT-Image.safetensors
     • HunyuanWorld-PanoInpaint-Scene.safetensors
     • HunyuanWorld-PanoInpaint-Sky.safetensors

4. Restart ComfyUI to load the new nodes.

Manual Installation (If automatic fails)

If the automatic installation encounters issues, install dependencies manually:

# Core requirements
C:\ComfyUI\.venv\Scripts\python.exe -m pip install -r requirements.txt

# Git-based dependencies
C:\ComfyUI\.venv\Scripts\python.exe -m pip install "git+https://github.com/EasternJournalist/utils3d.git"
C:\ComfyUI\.venv\Scripts\python.exe -m pip install "git+https://github.com/microsoft/MoGe.git"

# Additional HunyuanWorld dependencies
C:\ComfyUI\.venv\Scripts\python.exe -m pip install basicsr realesrgan zim-anything easydict

Troubleshooting

Import Errors: If you see "HunyuanWorld modules are not available", ensure all dependencies are installed. Run the installation verification:

C:\ComfyUI\.venv\Scripts\python.exe install.py

Model Requirements: The node pack automatically detects your ComfyUI installation and loads components from standard directories:

• FLUX models: C:\ComfyUI\models\unet\ (flux1-dev-fp8.safetensors, flux1-fill-dev.safetensors)
• HunyuanWorld LoRAs: C:\ComfyUI\models\Hunyuan_World\ (HunyuanWorld-PanoDiT-Text.safetensors, HunyuanWorld-PanoDiT-Image.safetensors)
• CLIP encoder: C:\ComfyUI\models\clip\clip_l.safetensors
• T5 encoder: C:\ComfyUI\models\text_encoders\t5xxl_fp16.safetensors
• FLUX VAE: C:\ComfyUI\models\vae\ae.safetensors

Recommended Offline Workaround:

1. Use ComfyUI's native FLUX Dev node to load flux1-dev-fp8.safetensors
2. Add LoRA Loader node with HunyuanWorld-PanoDiT-Text.safetensors
3. Generate panoramas using the combined FLUX + HunyuanWorld LoRA workflow
4. This provides the same panorama generation capability using ComfyUI's proven model loading system

VRAM Issues: Use CPU offloading and VAE tiling in the model loader settings for systems with limited VRAM.

Performance: For faster generation, ensure you have sufficient VRAM and use bfloat16 precision.
