Iterate Begin
(ComfyUI workflow included)
Iterate a sub-workflow by executing it from a data list sequentially in item-major order (as opposed to node-major)."
You need to connect the flow_control from a IterateBegin to a IterateEnd node.
Only use this if a sub-workflow takes a long time to process without any visible progress (see execution stalling problem).
Make sure to use the passthrough output slots on output nodes (Preview Image, Save Image etc.) so the intermediate results are visible.
Internally uses the node expansion mechanism which duplicates the sub-workflow multiple times for each list item.
lists use(s) is_output_list=True (indicated by the symbol 𝌠) and will be processed sequentially by corresponding nodes.
