ComfyUI Node: Stable Wildcard Output

Stable Wildcard Output:

Stable Wildcards is a custom node designed to enhance the reproducibility of AI-generated art by using a stable seed to process wildcards within prompts. This node allows you to define multiple options within curly braces {} in your prompt, and it will randomly select one of these options based on the provided seed. By using a consistent seed, the node ensures that the same prompt will always produce the same output, making it easier to recreate and refine your artistic workflows. This feature is particularly useful for artists who want to experiment with different variations of a prompt while maintaining control over the randomness, ensuring that the creative process remains both flexible and predictable.

Stable Wildcard Output Input Parameters:

prompt

The prompt parameter is a string input where you can define your creative prompt, including any wildcards enclosed in curly braces {}. These wildcards can contain multiple options separated by the | character. For example, {red|blue|green} will randomly select one of the colors based on the seed. This parameter supports multiline input and has dynamic prompts disabled to ensure that the prompt remains unchanged before processing. The default value is an empty string.

seed

The seed parameter is an integer that determines the randomness of the wildcard selection. By providing the same seed, you can ensure that the same prompt will always produce the same output, making your workflows reproducible. The seed must be a non-negative integer, with a minimum value of 0 and a maximum value determined by the system's maximum integer size. The default value is 0.

version

The version parameter is currently unused but reserved for future compatibility. It allows for backward compatibility in case of breaking changes. The default value is 1, and it is not expected to be modified by the user.

id (hidden)

The id parameter is a unique identifier used internally to save the result in metadata. It is not intended to be set by the user.

png_info (hidden)

The png_info parameter contains additional metadata, including workflow information. It is used internally to save the result in the metadata and is not intended to be set by the user.

Stable Wildcard Output Output Parameters:

Prompt String

The output parameter Prompt String is a string that contains the processed prompt with all wildcards replaced by the selected options. This output is crucial for generating consistent and reproducible results in your AI art projects. By using the same seed, you can ensure that the same prompt will always produce the same output, allowing for precise control over the creative process.

Stable Wildcard Output Usage Tips:

• To ensure reproducibility, always use the same seed when you want to recreate a specific output from a prompt with wildcards.
• Experiment with different seeds to explore various combinations of wildcard options and discover new creative possibilities.
• Use descriptive and varied options within your wildcards to maximize the creative potential of your prompts.

Stable Wildcard Output Common Errors and Solutions:

Workflow missing, output not saved in metadata

• Explanation: This error occurs when the png_info parameter does not contain workflow information, preventing the node from saving the result in the metadata.
• Solution: Ensure that the png_info parameter includes the necessary workflow information before executing the node.

Hidden input missing, output not saved in metadata

• Explanation: This error occurs when the required hidden inputs (id and png_info) are not provided, preventing the node from saving the result in the metadata.
• Solution: Ensure that both id and png_info parameters are correctly set before executing the node.
