Introduction

In this tutorial, we will explore the new features introduced in Episode 15 of the ComfyUI tutorial series. This episode focuses on enhancing your workflows through the use of custom styles, batch processing, and prompt management. By following these steps, you will learn how to effectively manage image generation tasks with ComfyUI.

Step 1: Install the itools Custom Node

To get started, you need to install the itools custom node, which adds additional functionalities to ComfyUI.

1. Access the Installation:

   • Navigate to the official ComfyUI repository or relevant source where the itools node is provided.

2. Download the itools Node:

   • Look for the latest version of the itools custom node and download the file.

3. Add the Node to ComfyUI:

   • Open ComfyUI and go to the custom nodes section.
   • Upload or import the itools node file you downloaded.

4. Verify the Installation:

   • Check if the itools node appears in your node palette. If it does, installation was successful.

Step 2: Create and Use Custom Styles Stored in YAML Files

Custom styles allow you to personalize your image generation process.

1. Create a YAML File:

   • Open a text editor and create a new file.
   • Save it with a .yaml extension.

2. Define Your Styles:

   • Structure your YAML file to include the styles you want. An example structure might look like this:

   styles:
     - name: "Style 1"
       parameters:
         contrast: 1.5
         brightness: 0.8
     - name: "Style 2"
       parameters:
         contrast: 1.2
         brightness: 1.0
   

3. Load the YAML File in ComfyUI:

   • In ComfyUI, navigate to the settings for styles and load your YAML file.
   • You should see the styles you defined available for use.

Step 3: Adding Text Overlay to Generated Images

Enhancing your images with text overlay can provide context or branding.

1. Select Image Output Node:

   • In ComfyUI, ensure your image output node is set up to receive the generated images.

2. Add Text Overlay Node:

   • Drag the text overlay node to your workspace and connect it to the image output node.

3. Configure Text Overlay:

   • Enter the text you want to overlay and adjust the font, size, and position as needed.

Step 4: Load Batch Images from a Folder

Batch loading images can save time and streamline your workflow.

1. Prepare Your Images:

   • Gather all images you want to process and place them in a single folder.

2. Use Batch Load Node:

   • In ComfyUI, add a batch load node to your workspace.

3. Configure the Batch Load Node:

   • Set the folder path where your images are stored.
   • Specify any processing parameters required for the images.

4. Run the Batch Process:

   • Start the process, and your images will be loaded and processed in bulk.

Step 5: Run Multiple Prompts from a File

Managing multiple prompts efficiently can enhance your image generation capabilities.

1. Create a Text File for Prompts:

   • Open a text editor and list all your prompts line by line.
   • Save the file with a .txt extension.

2. Load the Prompt File in ComfyUI:

   • In ComfyUI, add a prompt loader node.
   • Select the text file you created.

3. Execute the Prompts:

   • Start the execution, and ComfyUI will process each prompt in the file sequentially.
