ComfyUI Node: Runware Refiner

Runware Refiner:

The Runware Refiner is a specialized node designed to enhance the quality of image outputs by utilizing advanced models that focus on refining image details and improving overall coherence. This node is particularly beneficial when you aim to achieve superior quality, photorealism, or specific aesthetic enhancements in your images. The refiner models are based on the SDXL framework, ensuring that they are equipped with the latest advancements in image processing technology. By integrating the Runware Refiner into your workflow, you can significantly elevate the visual appeal and detail of your generated images, making it an essential tool for artists seeking high-quality results.

Runware Refiner Input Parameters:

Model

This parameter requires a connection to a Runware Model from the Model Search Node. It serves as the foundational model that the refiner will enhance, ensuring that the initial image generation is based on a robust and capable model.

startStep

The startStep parameter indicates the specific step number at which the refinement process begins. The initial model will generate the image up to this step, after which the refiner model takes over to enhance the result. This parameter allows for precise control over the transition point between the initial model and the refiner. The minimum value is 0, the maximum is 99, and the default is 0.

startStepPercentage

This parameter represents the percentage of total steps at which the refinement process begins. Similar to startStep, it determines when the refiner model takes over from the initial model, but in percentage terms. This allows for flexibility in defining the refinement point relative to the total number of steps. The minimum value is 0, the maximum is 99, and the default is 0.

Runware Refiner Output Parameters:

RUNWAREREFINER

The output of the Runware Refiner is a refined model encapsulated as RUNWAREREFINER. This output represents the enhanced image model that has undergone the refinement process, resulting in improved image quality and detail. The refined model can be used in subsequent image generation tasks to achieve higher quality outputs.

Runware Refiner Usage Tips:

• To achieve optimal results, carefully choose either startStep or startStepPercentage based on your specific needs. Avoid setting both parameters simultaneously to prevent errors.
• Experiment with different starting points for the refiner model to find the best balance between initial model generation and refinement for your specific artistic goals.

Runware Refiner Common Errors and Solutions:

"Please provide either startStep or startStepPercentage, not both."

• Explanation: This error occurs when both startStep and startStepPercentage are provided simultaneously, which is not allowed.
• Solution: Ensure that you only set one of these parameters at a time. Decide whether you want to specify the starting point in terms of steps or percentage and adjust your input accordingly.

"Please provide either startStep or startStepPercentage."

• Explanation: This error indicates that neither startStep nor startStepPercentage has been provided, which is required for the node to function.
• Solution: Provide a value for either startStep or startStepPercentage to define when the refinement process should begin.
