ComfyUI Node: GR Prompt Selector

GR Prompt Selector:

The GR Prompt Selector node is designed to streamline the process of selecting and combining text prompts for AI art generation. This node allows you to input multiple positive prompts and a single negative prompt, then dynamically select one of the positive prompts based on a specified index. The selected positive prompt is combined with an always-included positive prompt to create a comprehensive conditioning input for the AI model. This functionality is particularly useful for artists who want to experiment with different prompt combinations without manually adjusting the inputs each time. By automating the selection and combination process, the GR Prompt Selector enhances efficiency and creativity in AI art projects.

GR Prompt Selector Input Parameters:

clip

This parameter expects a CLIP model instance, which is used to tokenize and encode the text prompts. The CLIP model is essential for converting the text inputs into a format that the AI model can understand and process.

positive_a1

This is the first positive prompt string. It supports multiline and dynamic prompts, allowing for complex and varied input. This prompt is one of the selectable positive prompts.

positive_a2

This is the second positive prompt string. Similar to positive_a1, it supports multiline and dynamic prompts. This prompt is another option that can be selected based on the index.

positive_a3

This is the third positive prompt string. It also supports multiline and dynamic prompts, providing another selectable positive prompt.

positive_a4

This is the fourth positive prompt string. Like the others, it supports multiline and dynamic prompts, adding to the variety of selectable prompts.

positive_a5

This is the fifth positive prompt string. It supports multiline and dynamic prompts, offering another selectable positive prompt.

positive_a6

This is the sixth positive prompt string. It supports multiline and dynamic prompts, completing the set of selectable positive prompts.

always_a1

This is an always-included positive prompt string. It supports multiline and dynamic prompts and is combined with the selected positive prompt to form the final positive conditioning input.

negative_a1

This is the negative prompt string. It supports multiline and dynamic prompts and is used to create the negative conditioning input for the AI model.

select_prompt

This integer parameter specifies which positive prompt to select from the available options (positive_a1 to positive_a6). The value ranges from 1 to 6, with a default value of 1.

GR Prompt Selector Output Parameters:

positive

This output provides the positive conditioning input for the AI model. It is a combination of the selected positive prompt and the always-included positive prompt, encoded by the CLIP model.

negative

This output provides the negative conditioning input for the AI model. It is the encoded version of the negative prompt string.

prompts

This output is a string that includes both the combined positive prompt and the negative prompt. It is useful for debugging or understanding the exact prompts being used in the conditioning process.

GR Prompt Selector Usage Tips:

• Experiment with different combinations of positive prompts to see how they influence the AI-generated art. Use the select_prompt parameter to quickly switch between different prompts.
• Always include a well-thought-out always_a1 prompt to ensure that certain elements are consistently present in the generated art.
• Use multiline and dynamic prompts to create more complex and nuanced conditioning inputs, which can lead to more interesting and varied AI-generated art.

GR Prompt Selector Common Errors and Solutions:

Cannot execute because a node is missing the class_type property.

• Explanation: This error occurs when a required node property is missing, preventing the execution of the prompt.
• Solution: Ensure that all nodes have the necessary class_type property defined. Check the node configuration and add the missing property if necessary.

Cannot execute because node <class_type> does not exist.

• Explanation: This error indicates that the specified node class type does not exist in the current configuration.
• Solution: Verify that the class_type specified in the node configuration is correct and that the corresponding class is properly defined and imported.

Prompt has no outputs

• Explanation: This error occurs when the prompt configuration does not produce any outputs, which is required for execution.
• Solution: Ensure that the prompt configuration includes at least one valid output node. Check the node connections and make sure they are correctly set up to produce outputs.
