The Batch Masks node combines multiple individual mask inputs into a single batch. It takes a variable number of mask inputs and outputs them as a single batched mask tensor, allowing for batch processing of masks in subsequent nodes.

Inputs

Parameter	Data Type	Required	Range	Description
mask_0	MASK	Yes	-	The first mask input.
mask_1	MASK	Yes	-	The second mask input.
mask_2 to mask_49	MASK	No	-	Additional optional mask inputs. The node can accept a minimum of 2 and a maximum of 50 masks in total.

Note: This node uses an autogrow input template. You must connect at least two masks (mask_0 and mask_1). You can add up to 48 more optional mask inputs (mask_2 through mask_49) for a total of 50 masks. All connected masks will be combined into a single batch.

Outputs

Output Name	Data Type	Description
output	MASK	A single batched mask containing all the input masks stacked together.
