Originally posted by igorhero76-dev May 10, 2026 Hello,

First of all, thank you for the amazing work on Fooocus Plus. The workflow is already quite smooth, but I'd like to suggest a feature that would significantly improve the precision of the Inpaint/Outpaint process: an Eraser tool for mask creation.

Currently, when using automatic mask generation models (like isnet-general-use), the selection can sometimes be too broad, especially when subjects are close to each other.

To illustrate the need, here is a practical scenario:

-Adding a simple toggle between a Brush (to add to the mask) and an Eraser (to remove parts of it) would give users professional-level control directly within the Fooocus Plus interface.

What do you think about adding this to the roadmap?

Best regards,

Research direction
Explore the masking interface code (likely Gradio) to find the brush tool, then add an eraser mode that subtracts from the mask.
