ComfyUI Iterator Nodes

ComfyUI Iterator Nodes

A set of custom nodes for ComfyUI that allows you to iterate over files in a directory. This is useful for batch processing images or text files.

Features

• Iterator List Files: Scans a directory for files matching specific extensions and outputs them as a list.
• Iterator Load Image: Loads an image from a file path.
• Iterator Load String: Loads text content from a file path.

Installation

1. Navigate to your ComfyUI custom_nodes directory.
2. Clone this repository:

   git clone https://github.com/AIMovieStudio/comfyui-iterator.git
   

3. Restart ComfyUI.

Usage Guide

The core concept is to use Iterator List Files to generate a list of file paths, and then feed that list into Iterator Load Image or Iterator Load String.

Batch Processing Images

1. Add Iterator List Files node.
2. Set the directory to your image folder.
3. Set extension to png, jpg (or whatever you need).
4. Add Iterator Load Image node.
5. Connect file_paths from Iterator List Files to file_path on Iterator Load Image.
6. ComfyUI will automatically execute the Iterator Load Image node (and any subsequent nodes) for each file in the list.

Batch Processing Text

1. Add Iterator List Files node.
2. Set directory to your text folder.
3. Set extension to txt.
4. Add Iterator Load String node.
5. Connect file_paths to file_path.
