ComfyUI Node: SamplerRES_Momentumized

SamplerRES_Momentumized:

The SamplerRES_Momentumized node is designed to enhance the sampling process by incorporating momentum into the noise sampling mechanism. This node is particularly useful for AI artists looking to generate high-quality images with improved stability and consistency. By leveraging momentum, the sampler can produce smoother transitions and more coherent results, making it ideal for tasks that require fine-tuned control over the sampling process. The node offers a range of customizable parameters, allowing you to adjust the behavior of the sampler to suit your specific needs. Whether you're working on intricate designs or complex compositions, SamplerRES_Momentumized provides the flexibility and precision needed to achieve your artistic vision.

SamplerRES_Momentumized Input Parameters:

noise_sampler_type

This parameter specifies the type of noise sampler to be used. The available options are determined by the function get_noise_sampler_names(). Choosing the appropriate noise sampler type can significantly impact the quality and characteristics of the generated images.

momentum

This parameter controls the momentum applied during the sampling process. It accepts a floating-point value ranging from -1.0 to 1.0, with a default value of 0.5. Adjusting the momentum can help in achieving smoother transitions and more stable results. A higher momentum value can lead to more pronounced effects, while a lower value can make the sampling process more subtle.

denoise_to_zero

This boolean parameter determines whether the denoising process should be carried out to zero. The default value is True. Enabling this option can help in achieving cleaner and more refined outputs by fully denoising the sampled images.

simple_phi_calc

This boolean parameter specifies whether a simplified calculation method should be used for the phi function. The default value is False. Enabling this option can speed up the sampling process but may affect the quality of the results.

ita

This parameter controls the ita value used in the sampling process. It accepts a floating-point value ranging from 0.0 to 100.0, with a default value of 0.25. Adjusting the ita value can influence the behavior of the sampler, allowing for more precise control over the generated images.

c2

This parameter controls the c2 value used in the sampling process. It accepts a floating-point value ranging from 0.0 to 1.0, with a default value of 0.5. Adjusting the c2 value can affect the characteristics of the noise and the overall quality of the sampled images.

SamplerRES_Momentumized Output Parameters:

SAMPLER

The output of this node is a SAMPLER object configured with the specified parameters. This sampler can be used in subsequent nodes to generate images based on the defined noise sampling and momentum settings. The SAMPLER object encapsulates all the necessary information and methods to perform the sampling process, ensuring consistent and high-quality results.

SamplerRES_Momentumized Usage Tips:

• Experiment with different momentum values to find the optimal setting for your specific project. Higher values can create more dynamic effects, while lower values can produce more subtle and controlled results.
• Use the denoise_to_zero option to achieve cleaner outputs, especially when working on projects that require high levels of detail and refinement.
• Adjust the ita and c2 parameters to fine-tune the behavior of the sampler. These settings can significantly impact the quality and characteristics of the generated images.
