Pro Tips for Best Results

🔹 Input quality matters — Higher resolution input = sharper edges on output
🔹 Contrast helps — Images with clear subject/background contrast get the cleanest cuts
🔹 Works great on: people, products, animals, objects, logos
🔹 Challenging cases: glass, water, smoke, very similar colors to background
🔹 For challenging cases: Use the MASK output to refine in your preferred node (e.g., connect to a mask blur or manual paint node)

🖥️ System Requirements

Minimum Recommended GPU VRAM 2GB 4GB+ RAM 8GB 16GB+ ComfyUI Version 0.9.0+ Latest Python 3.10+ 3.11+ OS Win/Mac/Linux Any

CPU Mode: Works but significantly slower (~10-30s per image vs <1s on GPU)

❓ Troubleshooting

"InspyrenetRembg node not found" → Install the custom node via ComfyUI Manager and restart

"Model download failed" → Check internet connection. The model downloads from HuggingFace on first run

"Output has rough edges" → Try higher resolution input. Add a Gaussian blur node to the MASK output for softer edges

"Black background instead of transparent" → Make sure you're saving as PNG (not JPG). JPG doesn't support transparency
