Custom Nodes for ComfyUI

A collection of utility nodes for image processing, workflow management, and generation metadata tracking.

Installation

1. Navigate to your ComfyUI custom_nodes directory:

   cd ComfyUI/custom_nodes/
   

2. Clone this repository (or copy the folder seb-nodes-comfyui):

   git clone https://github.com/yourusername/seb-nodes-comfyui.git
   

3. Restart ComfyUI.
   • Connect the outputs of this node (Seed, Steps, etc.) to your actual KSampler node.
   • Connect text_overlay and start_time to the Generation Time node (optional).

2. Generation Time (SEB)

Category: sampling/control

Calculates the total generation time and appends it to your text overlay.

• Inputs:
  • image: The generated image (from VAE Decode).
  • text: The text_overlay output from the KSampler Bridge node.
  • start_time: The start_time output from the KSampler Bridge node.
• Outputs:
  • image: Passthrough of the input image.
  • text: Updated text string including "Time: X.XXs".
• How to Connect: Place this after your VAE Decode. Connect the image and the data from the Bridge node.

3. Text Label (SEB)

Combines multiple image batches into a single grid layout.

• Inputs: columns (grid width), padding, and up to 6 optional image inputs (image_1...image_6).
• Outputs: A single grid image.
• Usage: Useful for comparing results or creating contact sheets.

Example Workflow

1. KSampler Bridge -> (Pass parameters) -> KSampler -> VAE Decode -> Generation Time (Input Image).
2. KSampler Bridge -> (Pass text_overlay + start_time) -> Generation Time.
3. Generation Time -> (Pass image + text) -> Text Label.
4. Text Label -> Save Image.
