• No more messy connection lines across your canvas

Installation

Method 1: Manual Installation

1. Navigate to your ComfyUI custom nodes directory:

   cd ComfyUI/custom_nodes/

2. Clone or download this repository:

   git clone https://github.com/yourusername/DDM_Bundle.git

Or manually create a folder called DDM_Bundle and copy all files into it.

3. Restart ComfyUI

Method 2: ComfyUI Manager

Coming soon - install directly through ComfyUI Manager

Usage

Basic Example

1. Set a Value

   • Add a "DDM Set Value" node
   • Connect any output to it (image, latent, model, etc.)
   • Give it an ID like "my_image"

2. Get the Value

   • Add a "DDM Get Value" node anywhere else in your workflow
   • Type the same ID: "my_image"
   • The value will be retrieved automatically

Advanced Features

• Optional Default: Get Node has an optional default input if the value isn't found
• Pass-through: Set Node outputs the same value it receives, so you can chain them
• Any Type: Works with any ComfyUI data type automatically

Nodes

DDM Set Value

• Inputs:
  • value: Any type - the value to store
  • id: String - unique identifier for this value
• Outputs:
  • value: The same value (pass-through)

DDM Get Value

• Inputs:
  • id: String - identifier to retrieve
  • default (optional): Any type - fallback if ID not found
• Outputs:
  • value: The retrieved value

Tips

• Use descriptive IDs like "prompt_text", "final_image", "lora_model"
• Set nodes must execute before Get nodes (ComfyUI handles this automatically)
• IDs are case-sensitive
• Use the same ID in Set and Get nodes to connect them

Troubleshooting

Get node shows validation error?

• Make sure there's a Set node with the same ID somewhere in the workflow
• The validation should pass automatically with this version

Getting None values?

• Check that the Set node is actually executing (not disabled)
• Verify the ID matches exactly (case-sensitive)
• Make sure the Set node runs before the Get node

Version History

• v1.0.0 - Initial release
  • Set and Get nodes with proper validation
  • Support for all data types
  • Optional default values
