ComfyUI Node: Detail Daemon Sampler

Detail Daemon Sampler:

The DetailDaemonSamplerNode is a specialized node designed to enhance the sampling process by dynamically adjusting the sigma values passed to a model. This adjustment is crucial for refining the detail in generated outputs, allowing for more nuanced and precise results. The node operates by wrapping around an existing sampler and modifying the sigma values based on a custom schedule, which is determined by various parameters such as detail amount, start and end points, and other factors. This approach ensures that the sampling process remains consistent while providing the flexibility to fine-tune the level of detail in the output. By leveraging this node, you can achieve a higher degree of control over the sampling process, making it particularly beneficial for tasks that require detailed and high-quality outputs.

Detail Daemon Sampler Input Parameters:

sampler

The sampler parameter is an object that represents the base sampler to be wrapped by the DetailDaemonSamplerNode. It serves as the foundation upon which the node applies its sigma adjustments, ensuring that the underlying sampling process remains intact while allowing for enhanced detail control.

detail_amount

The detail_amount parameter is a float that dictates the intensity of detail enhancement applied during sampling. It ranges from -5.0 to 5.0, with a default value of 0.1. A higher value increases the level of detail, while a negative value reduces it, allowing for flexible control over the output's intricacy.

start

The start parameter is a float that specifies the starting point of the detail enhancement process within the sampling timeline. It ranges from 0.0 to 1.0, with a default value of 0.2. This parameter helps define when the detail adjustments begin, providing control over the timing of the enhancement.

end

The end parameter is a float that marks the endpoint of the detail enhancement process. It ranges from 0.0 to 1.0, with a default value of 0.8. This parameter, in conjunction with the start parameter, defines the duration over which the detail adjustments are applied, allowing for precise control over the enhancement period.

bias

The bias parameter is a float that influences the bias of the detail enhancement curve. It ranges from 0.0 to 1.0, with a default value of 0.5. This parameter adjusts the emphasis of the detail enhancement, enabling you to skew the adjustments towards the beginning or end of the sampling process.

exponent

The exponent parameter is a float that determines the curvature of the detail enhancement schedule. It ranges from 0.0 to 10.0, with a default value of 1.0. A higher exponent results in a steeper curve, affecting how quickly the detail adjustments are applied over time.

start_offset

The start_offset parameter is a float that modifies the starting point of the detail enhancement process. It ranges from -1.0 to 1.0, with a default value of 0.0. This parameter allows for fine-tuning of the initial phase of the enhancement, providing additional control over when the adjustments commence.

end_offset

The end_offset parameter is a float that adjusts the endpoint of the detail enhancement process. It ranges from -1.0 to 1.0, with a default value of 0.0. This parameter offers the ability to fine-tune the conclusion of the enhancement, ensuring that the adjustments end precisely as desired.

fade

The fade parameter is a float that controls the fading effect of the detail enhancement. It ranges from 0.0 to 1.0, with a default value of 0.0. This parameter allows for a gradual transition in the level of detail, smoothing out the enhancement process and preventing abrupt changes.

smooth

The smooth parameter is a boolean that determines whether the detail enhancement should be applied smoothly. With a default value of True, this parameter ensures that the adjustments are applied in a gradual and continuous manner, enhancing the overall quality of the output.

cfg_scale_override

The cfg_scale_override parameter is a float that allows for overriding the default configuration scale used in the sampling process. This parameter provides an additional layer of control over the sigma adjustments, enabling you to fine-tune the impact of the detail enhancement on the final output.

Detail Daemon Sampler Output Parameters:

SAMPLER

The output of the DetailDaemonSamplerNode is a modified SAMPLER object. This output retains the core functionality of the original sampler while incorporating the detail adjustments specified by the node's parameters. The enhanced sampler is capable of producing outputs with refined detail, making it a valuable tool for generating high-quality results.

Detail Daemon Sampler Usage Tips:

• Experiment with the detail_amount parameter to find the optimal level of detail for your specific task. A higher value can enhance intricate features, while a lower value may be suitable for simpler outputs.
• Utilize the start and end parameters to control the timing of the detail enhancement. Adjusting these values can help you focus the enhancements on specific parts of the sampling process, such as the beginning or end.

Detail Daemon Sampler Common Errors and Solutions:

"Invalid sigma range"

• Explanation: This error occurs when the sigma values fall outside the expected range during the sampling process.
• Solution: Ensure that the sigma values are correctly initialized and fall within the valid range specified by the node's parameters.

"Configuration scale override not applied"

• Explanation: This error indicates that the cfg_scale_override parameter was not correctly applied during the sampling process.
• Solution: Verify that the cfg_scale_override parameter is set to a valid value and that it is being passed correctly to the node.
