This Node Is Deprecated — This version of the node has been replaced with a new and improved version. The old version is kept for backwards-compatibility, but for all new workflows we suggest to use the version linked below.
Go to Suggested ReplacementRecursive Loop StartThe Recursive Loop node pair enables the passing of a data table from the Recursive Loop End back to the Recursive Loop Start.
The Loop Start requires an initialized table. This table is output by the Recursive Loop Start in the first iteration of the loop.
The table received by the corresponding Recursive Loop End is passed back to the Recursive Loop Start node. Starting with the second iteration, the Recursive Loop Start node outputs the data as received by the Recursive Loop End.
