BriaReplaceObject - ComfyUI Built-in Node Documentation - ComfyUI

Replaces an object in an image with a different one described in plain text, using Bria’s text-guided image editing. Bria re-renders the whole frame at about 1 megapixel, so the result is not pixel-aligned with the input.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
`image`	The image containing the object to be replaced. The alpha channel is dropped before the image is uploaded.	IMAGE	Yes	-
`instruction`	What to replace with what, such as “Replace the red apple with a green pear”. Must be at least 1 character long.	STRING	Yes	Multiline text; default: "" (empty)
`seed`	Bria takes no seed here and re-imagines the edit on each call, so repeated runs can differ. The value is never sent: it only changes this node’s cache key, so that an otherwise identical graph runs the edit again instead of returning the cached result.	INT	Yes	0 to 2147483647, step 1; default: 42; control after generate enabled

Moderation Inputs

Parameter	Description	Data Type	Required	Range
`moderation`	Moderation settings. Selecting “true” reveals the moderation sub-options below, which are otherwise not shown.	DYNAMIC_COMBO	Yes	`"false"` `"true"`
`visual_input_moderation`	Enables moderation of the input image. Only available when `moderation` is set to “true”.	BOOLEAN	No	`true` / `false`; default: false
`visual_output_moderation`	Enables moderation of the generated output image. Only available when `moderation` is set to “true”.	BOOLEAN	No	`true` / `false`; default: false

Note: instruction is validated before the request is sent and must contain at least 1 character. The seed value is not transmitted to Bria; it only affects whether the node re-runs the edit or returns a cached result.

Outputs

Output Name	Description	Data Type
`image`	The edited image with the described object replacement applied.	IMAGE
`structured_prompt`	Structured description of the edited image, for a follow-up edit with Bria FIBO Image Edit.	STRING
