## 🚀 Quick Start
### Method 1: Using Real Hunyuan3D Pipeline (Recommended)
```python
# 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
```python
# 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
```
LoadImage → HunyuanWorldModelLoader → HunyuanWorldImageTo3D → Preview3D
```
### Example 2: Advanced Pipeline
```
LoadImage → CLIPVisionEncode → Hunyuan3Dv2Conditioning →
EmptyLatentHunyuan3Dv2 → KSampler → VAEDecodeHunyuan3D →
VoxelToMesh → SaveGLB
```
### Example 3: Hybrid Approach
```
LoadImage → HunyuanWorldHybridNode (mode: direct_pipeline) → Preview
```
## 🆚 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"**
```bash
pip install -r requirements.txt
```
2. **CUDA out of memory**
```python
# Use these settings:
low_vram_mode=True
precision="fp16"
model_name="tencent/Hunyuan3D-2mini"
```
3. **Slow generation**
```python
# Optimize with:
resolution=1536 # instead of 3072
model_variant="mini"
```
4. **Poor mesh quality**
```python
# Try:
model_name="tencent/Hunyuan3D-2" # full model
resolution=3072
apply_texture=True
```
