ComfyUI Node: Topaz Upscale Settings

Topaz Upscale Settings:

The TopazUpscaleSettings node is designed to enhance the resolution and quality of images using advanced AI-driven upscaling techniques. This node leverages various models and parameters to upscale images, making them sharper, more detailed, and visually appealing. It is particularly useful for AI artists who want to improve the quality of their digital artwork or photographs without losing important details. By adjusting settings such as scale, denoise, deblur, and detail, you can achieve the desired level of enhancement, making this node a versatile tool for a wide range of image processing tasks.

Topaz Upscale Settings Input Parameters:

enabled

This parameter determines whether the upscaling process is enabled or not. It accepts two options: true and false, with the default value being true. When set to true, the upscaling process will be applied to the image; otherwise, it will be skipped.

model

This parameter allows you to select the AI model used for upscaling. The available options are Standard, Standard V2, High Fidelity, High Fidelity V2, and Low Resolution, with the default being Standard V2. Each model is optimized for different types of images and desired outcomes, providing flexibility in achieving the best results.

scale

This parameter sets the scaling factor for the upscaling process. It is a floating-point value with a default of 2.0, a minimum of 0, and a maximum of 10. Adjusting this value will increase or decrease the size of the output image proportionally.

denoise

This parameter controls the level of noise reduction applied during the upscaling process. It is a floating-point value with a default of 0.2, a minimum of 0, and a maximum of 10. Higher values will result in more aggressive noise reduction, which can help in cleaning up noisy images.

deblur

This parameter adjusts the amount of deblurring applied to the image. It is a floating-point value with a default of 0.2, a minimum of 0, and a maximum of 10. Increasing this value will help in reducing blur and enhancing the sharpness of the image.

detail

This parameter enhances the level of detail in the upscaled image. It is a floating-point value with a default of 0.2, a minimum of 0, and a maximum of 10. Higher values will bring out more details in the image, making it appear more defined and crisp.

Topaz Upscale Settings Output Parameters:

upscale_settings

This output parameter returns the configured TopazUpscaleSettings object. It encapsulates all the input settings and can be used in subsequent nodes or functions that require these specific upscaling configurations. This output is essential for ensuring that the upscaling process is carried out with the desired parameters.

Topaz Upscale Settings Usage Tips:

• Experiment with different models to find the one that best suits your image type and desired outcome.
• Start with the default values for denoise, deblur, and detail, and adjust them incrementally to see their effects on the image.
• Use a higher scale value for significant enlargements, but be mindful of potential quality loss if the value is too high.

Topaz Upscale Settings Common Errors and Solutions:

Topaz AI Upscaler not found at <path>

• Explanation: This error occurs when the specified path to the Topaz AI Upscaler executable is incorrect or the file is missing.
• Solution: Verify the path to the Topaz AI Upscaler executable and ensure that the file exists at the specified location.

compression must be between 0 and 10

• Explanation: This error indicates that the compression value provided is outside the acceptable range.
• Solution: Adjust the compression value to be within the range of 0 to 10.

Invalid model selected

• Explanation: This error occurs when an unsupported model name is provided.
• Solution: Ensure that the model name is one of the supported options: Standard, Standard V2, High Fidelity, High Fidelity V2, or Low Resolution.
