ComfyUI: Remove objects using Mask Editor and Inpainting

ComfyUITry it →Watch full video →pixaroma ·

Demo summary

The user demonstrates precisely removing a necklace from a portrait by painting a mask in the ComfyUI Mask Editor and using an inpainting prompt.

Step-by-step

  1. Install the required inpainting node from the ComfyUI Manager
  2. Upload the image containing the object you want to remove
  3. Right-click on the photo and select 'Open in Mask Editor'
  4. Adjust the brush thickness and paint over the object
  5. Save the mask
  6. Enter a prompt starting with 'remove' followed by details of the object
  7. Run the workflow to generate the inpainted result

Options

  • Adjust the thickness of the brush in the Mask Editor

Watch out for

  • You must have the specific inpainting node installed from the manager for the workflow to function
  • Standard model-only removal (without inpainting) will regenerate and change the entire image

Tips

  • Make the mask slightly larger than the object itself to allow for mask blurring
  • The mask does not have to be perfectly precise
  • Use inpainting instead of the base model alone to ensure only the masked area is affected while the rest of the image remains original

Highlights

“It removed the necklace really well. I like it a lot. So removing with inpaint seems to be a better way than removing with the model alone.”
