CondPassThrough

The CondPassThrough node technically implements a pass-through function, accepting two optional inputs of type CONDITIONING.

CondPassThrough is a simple conditioning pass-through node. Its core function is to receive and output positive and negative conditioning data unchanged. It does not perform any processing or modification, serving solely as a data conduit. It is primarily used to resolve connection issues in specific workflows.

Node Functionality

This node technically implements a pass-through function, accepting two optional inputs of type CONDITIONING. Its internal mechanism merely returns the input positive and negative parameters directly, without involving any data transformation or computation. It supports the standard ComfyUI conditioning data format. Its existence is mainly to bypass restrictions some nodes have on unconnected inputs.

Node Parameter Description - CondPassThrough

Inputs

Parameter Name	Data Type	Required	Default Value	Range/Options	Description
`positive`	CONDITIONING	No	-	-	The positive conditioning data to be output unchanged.
`negative`	CONDITIONING	No	-	-	The negative conditioning data to be output unchanged.

Outputs

Parameter Name	Data Type	Description
positive	CONDITIONING	The positive conditioning data output unchanged.
negative	CONDITIONING	The negative conditioning data output unchanged.

Usage Scenarios

In practical workflows, you can use this node when you need to temporarily "save" or "branch" a set of conditioning data to multiple downstream nodes. For example, in a complex prompt processing pipeline, you can input a set of base conditions into this node, then connect its outputs to different stylization or detail enhancement nodes, thereby achieving flexible distribution of the conditioning flow.

Notes

This node itself has no functional limitations, but note that its output depends entirely on its input. If the input is empty, the output will also be empty. It does not generate new conditioning data and is used only for flow control.
