MaskComposite - ComfyUI Built-in Node Documentation - ComfyUI

This node specializes in combining two mask inputs through a variety of operations such as addition, subtraction, and logical operations, to produce a new, modified mask. It abstractly handles the manipulation of mask data to achieve complex masking effects, serving as a crucial component in mask-based image editing and processing workflows.

Inputs

Parameter	Description	Data Type
`destination`	The primary mask that will be modified based on the operation with the source mask. It plays a central role in the composite operation, acting as the base for modifications.	MASK
`source`	The secondary mask that will be used in conjunction with the destination mask to perform the specified operation, influencing the final output mask.	MASK
`x`	The horizontal offset at which the source mask will be applied to the destination mask, affecting the positioning of the composite result.	INT
`y`	The vertical offset at which the source mask will be applied to the destination mask, affecting the positioning of the composite result.	INT
`operation`	Specifies the type of operation to apply between the destination and source masks, such as ‘add’, ‘subtract’, or logical operations, determining the nature of the composite effect.	COMBO[STRING]

Outputs

Parameter	Description	Data Type
`mask`	The resulting mask after applying the specified operation between the destination and source masks, representing the composite outcome.	MASK
