Connect the CYCLE Output of this node to a [Cycle Continue](#Cycle_Continue)'s CYCLE Input to begin the loop.
The first iteration of the loop is called a 'DRY RUN' and Data, Aux and
Index will all be set to None. Additionally the "Reset?" output will
return True so you can test this with an [IF Selector] node to determine
whether you are in the first execution of the loop. You can also trigger
a manual reset to the fist 'DRY RUN' iteration by toggling the Manual_Reset
Input. Use the 'DRY RUN' to reset any variables or the state of your
workflow whenever a fresh Cycle has started.

Set your Start, End and Step parameters to the values you would like to
iterate from, to and by, respectively. If you'd like the loop to return
automatically to the original Start value, enable the Auto_Reset Input,
otherwise the cycle will continue to apply Step to Index on each iteration.

This node uses the new Execution Inversion mechanics and requires an updated version of ComfyUI. It works by dynamically cloning all the nodes that are connected as children of the [Loop Open] and [Loop Close] nodes, while forwarding the data to the copies on each iteration. This is still a bit of proof of concept, so issues may occur. Please report any bugs on the Issues page of this node pack's Github repo!
