ComfyUI Noise extension offers 6 nodes for ComfyUI, enhancing control and flexibility over noise management.
ComfyUI_Noise is an extension for that provides enhanced control and flexibility over noise generation and manipulation in your AI art workflows. This extension is particularly useful for creating small variations in generated images or for finding the specific noise that corresponds to a given input image and prompt. By using ComfyUI_Noise, you can achieve more precise and creative results in your AI art projects.
ComfyUI_Noise operates by introducing several specialized nodes into the ComfyUI environment. These nodes allow you to generate, manipulate, and inject noise into image latents, which are the underlying data structures used in AI image generation. Think of noise as the "raw material" that the AI model sculpts into a final image. By controlling this noise, you can influence the outcome of the generated images in subtle or significant ways.
For example, if you want to create variations of an image, you can generate different noise patterns and blend them with the original noise. This process can be likened to adding different textures to a canvas to see how they affect the final painting.
This node generates noise that can be used in your workflows. You can find it under latent>noise
. The settings include:
This node duplicates a specific sample in a batch. It has been moved to the core functionality of ComfyUI, so you should use Latent>Batch>Repeat Latent Batch
and Latent>Batch>Latent From Batch
instead. The settings include:
This node blends two sets of latents together. You can find it under latent
. The settings include:
This node calculates the amount of noise a sampler expects when it starts denoising. You can find it under latent>noise
. The settings include:
This node injects noise into an image latent. You can find it under latent>noise
. The settings include:
This node reverses the sampling process to calculate the noise that would generate a given image. You can find it under sampling
. The settings include:
ComfyUI_Noise does not introduce new models but works with existing models in ComfyUI to manipulate noise. The nodes provided by ComfyUI_Noise can be used with any model supported by ComfyUI, allowing for a wide range of creative possibilities.
latent>noise
).Q: Can I use ComfyUI_Noise with any model? A: Yes, ComfyUI_Noise is designed to work with any model supported by ComfyUI.
Q: How do I create small variations of an image?
A: Use the Noisy Latent Image
node to generate noise, then blend it with the original noise using the Slerp Latents
node.
Q: What is the purpose of the Get Sigma
node?
A: The Get Sigma
node calculates the amount of noise a sampler expects, which is useful for precise noise injection.
