For Standard Python Installation:

pip install -r requirements.txt

4. Restart ComfyUI

📥 Model Download

Models will be automatically downloaded from HuggingFace when first used.

Manual Model Download (Optional)

If automatic download fails or you prefer manual installation:

1. Download using HuggingFace CLI:

huggingface-cli download zibojia/minimax-remover --include vae transformer scheduler --local-dir ./models/MiniMax-Remover

2. Or download manually from HuggingFace:

   • Visit: https://huggingface.co/zibojia/minimax-remover
   • Download the vae, transformer, and scheduler folders
   • Place them in: ComfyUI/models/MiniMax-Remover/

3. Verify installation:

   • Check that ComfyUI/models/MiniMax-Remover/ contains:
     • vae/ folder
     • transformer/ folder
     • scheduler/ folder

📦 Available Nodes

⚙️ Recommended Settings

MiniMax Model Loader (Advanced)

• scheduler_type: FlowMatchEulerDiscreteScheduler (recommended) or UniPCMultistepScheduler
• torch_dtype: float16 (GPU recommended) or float32 (CPU/compatibility)
• device: auto (automatic detection)

🎨 Mask Requirements

Supported Formats

• ✅ Grayscale images (recommended)
• ✅ RGB images (automatically converted)
• ✅ PNG, JPG, TIFF and other common formats

Mask Guidelines

• Black background, white foreground (standard mask format)
• High contrast for better edge detection
• Complete coverage of objects to remove
• Clean edges without excessive noise
• Avoid overly complex details in small areas

🚀 Performance Tips

GPU Memory Optimization

1. Use float16 precision (reduces memory by ~50%)
2. Keep image resolution reasonable (≤1024x1024 recommended)
3. Use fewer inference steps (6-12 usually sufficient)
4. Close other GPU applications to free VRAM

Processing Speed

1. FlowMatchEulerDiscreteScheduler is typically faster than UniPCMultistepScheduler
2. temporal_frames=3 provides best speed/quality balance
3. Use ImageSizeAdjuster node to optimize image dimensions for better performance

🔧 Requirements

System Requirements

• Python: 3.8 or higher
• GPU: NVIDIA GPU with CUDA support (recommended)
• RAM: 8GB+ system RAM
• VRAM: 6GB+ GPU memory for optimal performance

❓ Troubleshooting

Common Issues

Model Download Fails

• Try manual download from HuggingFace website
• Check internet connection and HuggingFace access
• Ensure sufficient disk space in ComfyUI/models/MiniMax-Remover/

CUDA Out of Memory

• Reduce image resolution
• Use float16 instead of float32
• Reduce num_inference_steps
• Close other applications using GPU

Tensor Dimension Errors

• Ensure mask and image have compatible dimensions
• Enable fix_dimensions in the All-in-One node for automatic adjustment
• Use ImageSizeAdjuster node for manual dimension control
• Check that images are RGB (not RGBA)

Dimension Warning Messages

• If you see "Image dimensions not divisible by 16" warning, enable fix_dimensions=True
• The All-in-One node will automatically suggest this when needed

Poor Removal Quality

• Increase num_inference_steps (try 16-20)
• Improve mask quality (higher contrast, cleaner edges)
• Adjust mask_dilation_iterations based on mask precision
• Try different scheduler types
