ComfyUI Node: Inject Noise

Inject Noise:

The BNK_InjectNoise node is designed to introduce noise into latent images, which can be particularly useful for AI artists looking to add variability or texture to their generated images. This node allows you to control the intensity of the noise and optionally apply a mask to specify where the noise should be injected. By manipulating the noise levels and areas affected, you can achieve a wide range of artistic effects, from subtle graininess to pronounced distortions. This node is essential for creating more dynamic and less predictable outputs, enhancing the creative possibilities of your AI-generated art.

Inject Noise Input Parameters:

latents

This parameter represents the latent image data that you want to modify by injecting noise. It is a required input and serves as the base upon which noise will be added.

strength

This parameter controls the intensity of the noise injected into the latent image. It is a floating-point value with a default of 1.0, a minimum of 0.0, and a maximum of 200.0. Adjusting this value allows you to fine-tune the amount of noise, with higher values resulting in more pronounced noise effects.

noise

This optional parameter allows you to provide a custom noise pattern to be injected into the latent image. If not provided, the node will use a default noise pattern. This can be useful if you want to apply a specific type of noise or reuse a noise pattern across multiple images.

mask

This optional parameter is a mask that specifies where the noise should be applied on the latent image. Areas covered by the mask will receive the noise, while areas outside the mask will remain unaffected. This allows for more targeted noise application, enabling you to preserve certain parts of the image while altering others.

Inject Noise Output Parameters:

LATENT

The output is a modified latent image with the injected noise. This latent image can then be used in subsequent processing steps or directly converted into a final image. The noise injection can add texture, variability, and artistic effects to the generated image, making it more dynamic and interesting.

Inject Noise Usage Tips:

• To achieve subtle noise effects, start with a low strength value (e.g., 0.1) and gradually increase it until you reach the desired level of noise.
• Use a mask to apply noise selectively to specific areas of the image, preserving important details while adding texture to less critical regions.
• Experiment with different custom noise patterns to see how they affect the final output, allowing for unique and varied artistic results.

Inject Noise Common Errors and Solutions:

warning, shapes in InjectNoise not the same, ignoring

• Explanation: This warning occurs when the shapes of the latent image and the provided noise pattern do not match.
• Solution: Ensure that the noise pattern has the same dimensions as the latent image before injecting it. You may need to resize or reshape the noise pattern to match the latent image's dimensions.
