MaskComposite - ComfyUI Built-in Node Documentation

Complete documentation for the MaskComposite node in ComfyUI. Learn its inputs, outputs, parameters and usage.

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	Data Type	Description
destination	MASK	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.
source	MASK	The secondary mask that will be used in conjunction with the destination mask to perform the specified operation, influencing the final output mask.
x	INT	The horizontal offset at which the source mask will be applied to the destination mask, affecting the positioning of the composite result.
y	INT	The vertical offset at which the source mask will be applied to the destination mask, affecting the positioning of the composite result.
operation	COMBO[STRING]	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.

Outputs

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