LoopResult - ComfyUI Built-in Node Documentation

LoopResult is a developer-only output node that marks the closing point of a loop block. It collects the values that are passed into it in order (named output0, output1, and so on) and releases the external execution block identified by a close ID. Because input fingerprinting always returns NaN, the node is treated as always changed and is re-executed every run.

Inputs

Parameter	Description	Data Type	Required	Range
`close_id`	Identifier of the loop block to close; only the first value of the list is used	STRING	Yes	-
`output0`, `output1`, …	Values collected from the loop block. The node accepts any additional inputs and gathers them in sequential order starting at `output0`, stopping at the first missing index	Any type	No	-

Note: This node accepts all inputs (accept_all_inputs). Any input beyond close_id is treated as a collected loop value and must be named output0, output1, output2, etc., without gaps, for it to be included in the result.

Outputs

This node does not return any outputs. It only releases the external execution block associated with close_id.
