ComfyUI Job Iterator

Implements iteration over sequences within a single workflow run.

Fixing Old Workflows

Replace the old JobIterator node with the new JobToList node.

Installation

Just clone into custom_nodes. There are no dependencies.

Usage

  1. Make a SEQUENCE containing the values to use at each step.
  2. Turn it into a JOB using a MakeJob node, and enter a name for the attribute.
  3. If you need to modify more than one parameter, make more SEQUENCES and turn them into JOBs.
  4. Connect to a JobToList.
  5. Connect the attributes output to GetAttribute nodes to pull out the value of a name at the current step.
  6. Connect those values into a normal workflow.
  7. Click "queue prompt".
