FluxEraseNode - ComfyUI Built-in Node Documentation - ComfyUI

Removes the masked object from an image and reconstructs the background. Paint the mask over what you want to erase, and the node fills in the area with plausible background content.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The input image to process	IMAGE	Yes	-
`mask`	White areas are removed; black areas are preserved	MASK	Yes	-
`dilate_pixels`	Expands the mask boundaries to ensure clean coverage of the object’s edges (default: 10)	INT	Yes	0 to 25
`seed`	The random seed used for creating the noise (default: 0)	INT	No	0 to 2147483647

Note: The input image must be at least 256x256 pixels in both dimensions. The mask is automatically resized to match the image dimensions, and the image’s alpha channel is removed before processing.
