RecraftReplaceBackgroundNode - ComfyUI Built-in Node Documentation - ComfyUI

Replace background on image, based on provided prompt. This node uses the Recraft API to generate new backgrounds for your images according to your text description, allowing you to completely transform the background while keeping the main subject intact.

`prompt`	Prompt for the image generation (default: empty)	STRING	Yes	-
`n`	The number of images to generate (default: 1)	INT	Yes	1-6
`seed`	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0)	INT	Yes	0-18446744073709551615
