CCM Sampler Description

Facilitates advanced sampling techniques for AI artists within ComfyUI, generating high-quality samples with flexible parameter tuning.

CCM Sampler:

The CCMSampler node is designed to facilitate advanced sampling techniques within the ComfyUI framework, specifically tailored for AI artists who want to enhance their creative workflows. This node provides a robust and flexible method for generating high-quality samples from latent images, leveraging sophisticated algorithms to ensure optimal results. By integrating seamlessly with other nodes and components, CCMSampler allows you to fine-tune various parameters to achieve the desired artistic effects, making it an essential tool for anyone looking to push the boundaries of AI-generated art.

CCM Sampler Input Parameters:


This parameter specifies the model to be used for sampling. It is crucial as it determines the underlying architecture and capabilities of the sampling process. The model parameter does not have a default value and must be provided.


The seed parameter is an integer that initializes the random number generator, ensuring reproducibility of the sampling process. The default value is 0, with a minimum of 0 and a maximum of 0xffffffffffffffff. Using different seeds will produce different samples, even with the same input parameters.


This integer parameter defines the number of steps to be taken during the sampling process. More steps generally lead to higher quality samples but at the cost of increased computation time. The default value is 20, with a minimum of 1 and a maximum of 10000.


The cfg (classifier-free guidance) parameter is a float that controls the strength of the guidance during sampling. Higher values result in stronger guidance, which can lead to more pronounced features in the generated samples. The default value is 8.0, with a range from 0.0 to 100.0, adjustable in steps of 0.1.


This parameter allows you to select the specific sampling algorithm to be used. The available options are defined by comfy.samplers.KSampler.SAMPLERS. Choosing the right sampler can significantly impact the quality and style of the generated samples.


The scheduler parameter specifies the scheduling algorithm to be used during sampling. The available options are defined by comfy.samplers.KSampler.SCHEDULERS. Different schedulers can affect the convergence and quality of the sampling process.


This parameter represents the positive conditioning to be applied during sampling. It is essential for guiding the model towards desired features and characteristics in the generated samples.


The negative parameter represents the negative conditioning, which helps in steering the model away from undesired features. Balancing positive and negative conditioning is key to achieving high-quality results.


This parameter is the latent image to be used as the starting point for sampling. It serves as the initial input from which the sampling process generates the final output.


The denoise parameter is a float that controls the amount of denoising applied during the sampling process. The default value is 1.0, with a range from 0.0 to 1.0, adjustable in steps of 0.01. Lower values result in less denoising, preserving more of the original noise in the latent image.

CCM Sampler Output Parameters:


The output of the CCMSampler node is a latent image, which is a high-dimensional representation of the generated sample. This latent image can be further processed or decoded to produce the final visual output. The quality and characteristics of the latent image depend on the input parameters and the sampling process.

CCM Sampler Usage Tips:

  • Experiment with different seed values to explore a variety of generated samples from the same input parameters.
  • Adjust the steps parameter to find a balance between sample quality and computation time, especially for complex or high-resolution images.
  • Use the cfg parameter to fine-tune the guidance strength, which can help in achieving the desired artistic effects in the generated samples.
  • Select different samplers and schedulers to understand their impact on the sampling process and choose the one that best fits your creative needs.

CCM Sampler Common Errors and Solutions:

"Model not specified"

  • Explanation: The model parameter is missing or not provided.
  • Solution: Ensure that you specify a valid model before running the CCMSampler node.

"Invalid seed value"

  • Explanation: The seed parameter is out of the acceptable range.
  • Solution: Provide a seed value within the range of 0 to 0xffffffffffffffff.

"Steps out of range"

  • Explanation: The steps parameter is set to a value outside the allowed range.
  • Solution: Adjust the steps parameter to be within the range of 1 to 10000.

"Invalid cfg value"

  • Explanation: The cfg parameter is set to a value outside the allowed range.
  • Solution: Ensure the cfg value is between 0.0 and 100.0.

"Sampler or scheduler not recognized"

  • Explanation: The specified sampler or scheduler is not recognized.
  • Solution: Verify that the sampler_name and scheduler parameters are set to valid options defined by comfy.samplers.KSampler.SAMPLERS and comfy.samplers.KSampler.SCHEDULERS, respectively.
