| Feature | Description | |---------|-------------| | 🖼️ Image to 3D | Convert any image into a detailed 3D model | | 🎨 AI Enhancement | Automatic photorealistic enhancement of input images | | 🌟 PBR Textures | Generate models with physically-based rendering textures | | 📐 Multiple Resolutions | Choose from 500K, 1M, or 1.5M polygons | | 🔷 Low Poly Mode | Create optimized game-ready models | | 🧩 Part Segmentation | Automatic segmentation of 3D model components | | ⚡ Async Processing | Non-blocking generation with progress tracking |
📦 Installation
Prerequisites
- Download and install ComfyUI from comfy.org/download
- Launch ComfyUI at least once to initialize the directory structure
Method 1: Git Clone
cd ComfyUI/custom_nodes
git clone https://github.com/SofianeAlla/ComfyUI-BespokeAI-3D.git
cd ComfyUI-BespokeAI-3D
pip install -r requirements.txt
Method 2: Download ZIP
- Download the latest release
- Extract to
ComfyUI/custom_nodes/ - Install dependencies:
pip install -r requirements.txt - Restart ComfyUI
Required Companion Nodes
This node works with the following built-in ComfyUI nodes:
- Load Image (
Charger Image) - To provide image input to the 3D generation node - 3D Preview (
Aperçu 3D) - To preview the generated 3D model directly in ComfyUI
🔑 Getting Your API Key
- Visit bespokeai.build
- Create an account or sign in
- Navigate to Settings → API
- Generate your API key (starts with
bspk_)
💡 Tip: Keep your API key secure and never commit it to version control!
🚀 Quick Start
- Add a Load Image node
- Add BespokeAI 3D Generation node (found in
BespokeAI/3D) - Connect the image output to the node
- Enter your API key
- Configure options and run!

📸 Examples
Basic Image to 3D
Load Image → BespokeAI 3D Generation → 3D Preview
The screenshot above shows the correct node setup:
- Load Image (Charger Image) - Load your source image
- BespokeAI 3D Generation - Connect the image, enter your API key, and configure options
- 3D Preview (Aperçu 3D) - Connect the
mesh_pathoutput to preview the generated 3D model
With AI Enhancement + Segmentation
Load Image → BespokeAI 3D Generation → Save GLB
↓
Resolution: 500k
AI Enhancement: ✓
Segmentation: ✓
Batch Processing Workflow
Load Image Batch → Loop → BespokeAI 3D Generation → Collect → Save All
💰 Pricing

└── model_1699999999.obj
⚠️ Troubleshooting
<details> <summary><strong>❌ "Invalid API key" error</strong></summary>- Verify your API key starts with
bspk_ - Check that the key hasn't been revoked
- Ensure no extra spaces in the key field
- Add more credits at bespokeai.build
- Disable optional features to reduce credit usage
- Check your current balance in the dashboard
- Wait 1 minute before retrying
- Rate limit: 20 requests per minute
- Consider batching requests with delays
- Segmentation only works with 500k resolution
- The node automatically switches to 500k when enabled
- Check console for warnings
- Increase
max_poll_attempts(default: 120) - Check your internet connection
- Complex images may take longer to process
- Try with a simpler/cleaner input image
