ComfyUI-DynamicPrompts Custom Nodes

ComfyUI-DynamicPrompts is a custom nodes library that integrates into your existing ComfyUI Library. It provides nodes that enable the use of Dynamic Prompts in your ComfyUI. The nodes provided in this library are:

1. Random Prompts - Implements standard wildcard mode for random sampling of variants and wildcards.
2. Combinatorial Prompts - Iterates through every possible combination of random values in a prompt.
3. I'm Feeling Lucky - Uses the given prompt to download a related prompt from Lexica.art.
4. Magic Prompt - Employs a neural network to add relevant modifiers to your prompt.
5. Jinja2 Templates - Allows you to write prompts using Jinja2 templates.

Nodes can be found in the Dynamic Prompts menu:

Installation

Using ComfyUI-Manager

1. Install ComfyUI-Manager if it isn't already.
2. Press Install Custom Nodes from the ComfyUI-Manager menu
3. Search for dynamicprompts
4. Click install

Manual installation

Follow the steps below to install the ComfyUI-DynamicPrompts Library. These commands assume the your current working directory is the ComfyUI root directory.

1. Clone the repository:

   git clone https://github.com/adieyal/comfyui-dynamicprompts custom_nodes/comfyui-dynamicprompts

2. Install the required Python packages:

   python -m pip install -r custom_nodes/comfyui-dynamicprompts/requirements.txt

3. Run install.py:

   python custom_nodes/comfyui-dynamicprompts/install.py

4. mkdir custom_nodes/comfyui-dynamicprompts/wildcards
5. (Optional) download a wildcard collection and copy it into this new wildcards folder.
6. Restart your ComfyUI.
7. Example workflows can be found in custom_nodes/comfyui-dynamicprompts/example_workflows.

Wildcards

The extension looks for wildcard files in custom_nodes/comfyui-dynamicprompts/wildcards. It supports wildcard files in .txt, .json and .yaml (example format).

There are many pre-built wildcards collections available. Here are a few to get you started:

• SD Dynamic Prompts built-in
• Civitai wildcard packs

Node Outputs

All nodes in this library produce a String output that can typically be passed into Clip Text Encode Prompts. Both positive and negative nodes are supported.

Please note, since ComfyUI is inherently stateless, some nodes might have a slightly unexpected behavior:

• The Combinatorial Prompt generation iterates through all possible values in a cycle. For example, A {red|green|blue} ball will generate the following sequence:

  • A red ball
  • A green ball
  • A blue ball
  • A red ball
  • ...

• The I'm Feeling Lucky, Magic Prompt, and Jinja2 nodes have an optional auto refresh parameter. If set to True, a new prompt is generated for every iteration. However, if set to False, a prompt will be downloaded once and used for subsequent generations.

Roadmap

1. This is a quick and dirty release with some known limitations such as non-configurable random seeds, inability to select the MagicPrompt model, and absence of several other configuration features.
2. Currently, the only way to view the generated prompt is through console output. A future release will introduce nodes to display the generate prompt on screen and to write it to a file.
3. It is not currently possible to chain generators, this functionality will be added in future releases.
4. The installation script will be automated in the future for ease of use.
