🚀 Quick Start

Method 1: Using Real Hunyuan3D Pipeline (Recommended)

# 1. Load the model
model_loader = HunyuanWorldModelLoader()
pipeline = model_loader.load_model(
    model_name="tencent/Hunyuan3D-2mini",  # Faster, less VRAM
    precision="fp16",
    enable_texture=True,
    low_vram_mode=True
)

# 2. Generate 3D from image
generator = HunyuanWorldImageTo3D()
mesh_path, info, preview = generator.generate_3d(
    pipeline=pipeline,
    image=your_image,
    apply_texture=True,
    save_mesh=True,
    filename_prefix="my_3d_model"
)

Method 2: Simplified Wrapper

# One-click 3D generation
simple_wrapper = HunyuanWorldSimplifiedWrapper()
result_info, preview = simple_wrapper.simple_generate(
    image=your_image,
    model_variant="mini",  # or "standard", "multiview"
    resolution=1024,
    enable_texture=True,
    filename_prefix="simple_3d"
)

🔧 Using Native ComfyUI Hunyuan3D Nodes

ComfyUI already includes powerful Hunyuan3D nodes. Here's how to use them:

Basic Workflow:

1. EmptyLatentHunyuan3Dv2 - Create latent space

   resolution: 3072 (or 1536 for faster generation)
   batch_size: 1
   

2. CLIPVisionLoader + CLIPVisionEncode - Process input image

   Load CLIP vision model → Encode your image
   

3. Hunyuan3Dv2Conditioning - Create conditioning

   Connect CLIP vision output → Get positive/negative conditioning
   

4. Load Hunyuan3D Model + KSampler - Generate

   Load model → Sample with conditioning → Get latent output
   

5. VAEDecodeHunyuan3D - Decode to voxels

   latent → voxels (with octree_resolution: 256)
   

6. VoxelToMesh - Convert to mesh

   voxels → mesh (with threshold: 0.5)
   

7. SaveGLB - Save final result

   mesh → GLB file
   

Advanced Multi-View Workflow:

Use Hunyuan3Dv2ConditioningMultiView for better results:

front_image → CLIP encode → front conditioning
left_image → CLIP encode → left conditioning
back_image → CLIP encode → back conditioning
right_image → CLIP encode → right conditioning
→ Combine in MultiView node → Enhanced conditioning

🎛️ Model Variants

tencent/Hunyuan3D-2

• Best quality but requires more VRAM
• Recommended for: High-quality final outputs
• VRAM requirement: ~8GB+

tencent/Hunyuan3D-2mini

• Balanced quality and speed
• Recommended for: Most users, development, testing
• VRAM requirement: ~4GB+

tencent/Hunyuan3D-2mv

• Multi-view optimized
• Recommended for: When you have multiple view images
• VRAM requirement: ~6GB+

💡 Tips and Best Practices

For Best Results:

1. Use high-quality input images (512x512 or higher)
2. Clear subject isolation - objects with clean backgrounds work better
3. Good lighting - avoid harsh shadows or overexposure
4. Single objects - works better than complex scenes

Performance Optimization:

1. Use fp16 precision for 2x speed improvement
2. Enable low_vram_mode if you have limited GPU memory
3. Start with mini model for testing, upgrade to full model for final output
4. Use smaller resolutions (1536 instead of 3072) for faster iteration

Troubleshooting:

• Out of memory: Enable low_vram_mode, use fp16, or use mini model
• Poor quality: Try full model, higher resolution, or better input image
• Import errors: Install requirements with pip install -r requirements.txt

🔄 Workflow Examples

Example 1: Quick 3D Generation

Example 2: Advanced Pipeline

LoadImage → CLIPVisionEncode → Hunyuan3Dv2Conditioning →
EmptyLatentHunyuan3Dv2 → KSampler → VAEDecodeHunyuan3D →
VoxelToMesh → SaveGLB

Example 3: Hybrid Approach

🆚 Comparison: Custom vs Built-in Nodes

Feature	Custom Nodes	Built-in ComfyUI Nodes
Ease of use	⭐⭐⭐⭐⭐ Simple	⭐⭐⭐ Complex workflow
Flexibility	⭐⭐⭐ Good	⭐⭐⭐⭐⭐ Maximum
Performance	⭐⭐⭐⭐ Direct	⭐⭐⭐⭐⭐ Optimized
Memory usage	⭐⭐⭐ Standard	⭐⭐⭐⭐⭐ Efficient
Customization	⭐⭐⭐ Limited	⭐⭐⭐⭐⭐ Full control

Recommendation:

• Beginners: Use custom simplified wrapper
• Advanced users: Use built-in ComfyUI workflow
• Developers: Use hybrid approach for maximum flexibility

🐛 Troubleshooting

Common Issues:

1. "Hunyuan3D libraries not available"

   pip install -r requirements.txt

2. CUDA out of memory

   # Use these settings:
   low_vram_mode=True
   precision="fp16"
   model_name="tencent/Hunyuan3D-2mini"

3. Slow generation

   # Optimize with:
   resolution=1536  # instead of 3072
   model_variant="mini"

4. Poor mesh quality

   # Try:
   model_name="tencent/Hunyuan3D-2"  # full model
   resolution=3072
   apply_texture=True
