ConditioningCombine - ComfyUI Built-in Node Documentation

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

This node combines two conditioning inputs into a single output, effectively merging their information. The two conditions are combined using list concatenation.

Inputs

Parameter Name	Data Type	Description
conditioning_1	CONDITIONING	The first conditioning input to be combined. It has equal importance with conditioning_2 in the combination process.
conditioning_2	CONDITIONING	The second conditioning input to be combined. It has equal importance with conditioning_1 in the combination process.

Outputs

Parameter Name	Data Type	Description
conditioning	CONDITIONING	The result of combining conditioning_1 and conditioning_2, encapsulating the merged information.

Usage Scenarios

Compare the two groups below: the left side uses the ConditioningCombine node, while the right side shows normal output.

In this example, the two conditions used in Conditioning Combine have equivalent importance. Therefore, you can use different text encodings for image style, subject features, etc., allowing the prompt features to be output more completely. The second prompt uses the combined complete prompt, but semantic understanding may encode completely different conditions.

Using this node, you can achieve:

• Basic text merging: Connect the outputs of two CLIP Text Encode nodes to the two input ports of Conditioning Combine
• Complex prompt combination: Combine positive and negative prompts, or separately encode main descriptions and style descriptions before merging
• Conditional chain combination: Multiple Conditioning Combine nodes can be used in series to achieve gradual combination of multiple conditions
