Mask
Select only the area that needs a change.

When an AI image is almost right, I regenerate only the part that is wrong. Everything else stays untouched.
Hands, feet and fingers are where AI images break. I find them at 100% zoom and regenerate only those areas with local open-source models in ComfyUI.

Select only the area that needs a change.
Test the revision inside the mask.
Check the fix at 100% and compare the untouched areas.
Malformed hands and feet spoiled otherwise good images. A throw color change would normally mean rendering the whole room again.
A mask-based revision workflow with local open-source models in ComfyUI. I test denoise strengths and seeds only inside the selected area.
An AI agent (Claude) connected to ComfyUI through MCP runs each fix while I direct or review the next image.
The hands and feet are corrected, and the navy throw becomes red. The surrounding image stays untouched.
