ComfyUI Node: PreSampling (NoiseIn)

PreSampling (NoiseIn):

The easy preSamplingNoiseIn node is designed to facilitate the process of adding noise to latent images before sampling in AI art generation workflows. This node is particularly useful for artists looking to introduce controlled randomness into their generated images, which can help in creating more diverse and unique outputs. By leveraging this node, you can fine-tune the noise parameters to achieve the desired level of detail and texture in your artwork. The node integrates seamlessly with other components in the pipeline, ensuring that the noise addition process is both efficient and effective.

PreSampling (NoiseIn) Input Parameters:

scheduler

The scheduler parameter determines the scheduling algorithm used for noise addition. It combines the default schedulers from comfy.samplers.KSampler with any new schedulers you may have added. This parameter influences how noise is distributed over the sampling steps, affecting the final image's texture and detail.

denoise

The denoise parameter is a floating-point value that controls the level of denoising applied during the noise addition process. It ranges from 0.0 to 1.0, with a default value of 1.0. A higher value results in less noise and a cleaner image, while a lower value retains more noise, adding texture and complexity to the image.

seed

The seed parameter is an integer that sets the random seed for noise generation. It ranges from 0 to MAX_SEED_NUM, with a default value of 0. Setting a specific seed ensures reproducibility, allowing you to generate the same noise pattern across different runs.

optional_noise_seed

The optional_noise_seed parameter is an optional integer input that forces the use of a specific noise seed. This parameter is useful when you want to override the default seed setting for more controlled noise generation.

optional_latent

The optional_latent parameter is an optional input that accepts a latent image. If provided, this latent image will be used as the base for noise addition, allowing for more customized noise application.

PreSampling (NoiseIn) Output Parameters:

pipe

The pipe output parameter returns the processed pipeline after noise has been added to the latent image. This output can be used as an input to subsequent nodes in your AI art generation workflow, ensuring that the added noise is properly integrated into the final image generation process.

PreSampling (NoiseIn) Usage Tips:

• Experiment with different denoise values to find the right balance between noise and clarity in your images.
• Use the seed parameter to ensure reproducibility when you find a noise pattern that you like.
• Leverage the optional_latent input to apply noise to specific latent images, allowing for more targeted noise addition.

PreSampling (NoiseIn) Common Errors and Solutions:

InjectNoiseToLatent: No noise provided

• Explanation: This error occurs when no noise input is provided to the node.
• Solution: Ensure that you provide a valid noise input or configure the node to generate noise automatically.

InjectNoiseToLatent: No input latent provided

• Explanation: This error occurs when no latent image is provided for noise addition.
• Solution: Provide a valid latent image input to the node to proceed with noise addition.

InjectNoiseToLatent: Latent and noise must have the same shape

• Explanation: This error occurs when the shapes of the latent image and noise do not match.
• Solution: Ensure that the latent image and noise inputs have the same shape before passing them to the node.
