ComfyUI Node: 🌫 Noise from Area Palettes

Noise from Area Palettes [Dream]:

The "Noise from Area Palettes [Dream]" node is designed to generate complex and visually appealing noise patterns by leveraging multiple color palettes assigned to different areas of an image. This node allows you to create intricate textures and backgrounds by blending colors from various palettes, each mapped to specific regions of the image. The node's primary goal is to provide a versatile tool for generating noise that can be used in a wide range of artistic applications, from abstract art to detailed textures. By adjusting parameters such as blur amount, density, and area sharpness, you can fine-tune the noise generation process to achieve the desired visual effect.

Noise from Area Palettes [Dream] Input Parameters:

area_sharpness

This parameter controls the sharpness of the transitions between different areas of the image where different palettes are applied. A higher value results in sharper transitions, while a lower value creates smoother blends. The default value is 0.5, with a minimum of 0.0 and a maximum of 1.0, adjustable in steps of 0.05.

width

Specifies the width of the generated image in pixels. The default value is 512, with a minimum of 1 and a maximum of 8192 pixels. Adjusting this parameter changes the horizontal dimension of the output image.

height

Specifies the height of the generated image in pixels. The default value is 512, with a minimum of 1 and a maximum of 8192 pixels. Adjusting this parameter changes the vertical dimension of the output image.

blur_amount

Determines the amount of blur applied to the noise pattern. A higher value results in a more blurred image, while a lower value keeps the noise pattern sharper. The default value is 0.3, with a minimum of 0 and a maximum of 1.0, adjustable in steps of 0.05.

density

Controls the density of the noise pattern. A higher value results in a denser noise pattern, while a lower value creates a sparser pattern. The default value is 0.5, with a minimum of 0.1 and a maximum of 1.0, adjustable in steps of 0.025.

seed

Sets the seed for the random number generator used in the noise generation process. This allows for reproducibility of the noise pattern. The default value is 0, with a minimum of 0 and a maximum of 0xffffffffffffffff.

top_left_palette

Optional parameter that specifies the color palette to be used for the top-left area of the image. This parameter accepts an RGBPalette ID.

top_center_palette

Optional parameter that specifies the color palette to be used for the top-center area of the image. This parameter accepts an RGBPalette ID.

top_right_palette

Optional parameter that specifies the color palette to be used for the top-right area of the image. This parameter accepts an RGBPalette ID.

center_left_palette

Optional parameter that specifies the color palette to be used for the center-left area of the image. This parameter accepts an RGBPalette ID.

center_palette

Optional parameter that specifies the color palette to be used for the center area of the image. This parameter accepts an RGBPalette ID.

center_right_palette

Optional parameter that specifies the color palette to be used for the center-right area of the image. This parameter accepts an RGBPalette ID.

bottom_left_palette

Optional parameter that specifies the color palette to be used for the bottom-left area of the image. This parameter accepts an RGBPalette ID.

bottom_center_palette

Optional parameter that specifies the color palette to be used for the bottom-center area of the image. This parameter accepts an RGBPalette ID.

bottom_right_palette

Optional parameter that specifies the color palette to be used for the bottom-right area of the image. This parameter accepts an RGBPalette ID.

The output is provided in a format that can be easily integrated into various digital art workflows.

Noise from Area Palettes [Dream] Usage Tips:

• Experiment with different area_sharpness values to achieve the desired transition effect between different palettes.
• Use the seed parameter to generate reproducible noise patterns, which can be useful for creating consistent textures across multiple projects.
• Adjust the blur_amount and density parameters to fine-tune the visual complexity and texture of the noise pattern.
• Assign different palettes to various areas of the image to create unique and visually interesting compositions.

Noise from Area Palettes [Dream] Common Errors and Solutions:

"Invalid palette ID"

• Explanation: This error occurs when an invalid or non-existent palette ID is provided.
• Solution: Ensure that the palette ID you are using is valid and exists in the system.

"Width or height out of range"

• Explanation: This error occurs when the specified width or height is outside the allowed range.
• Solution: Adjust the width and height parameters to be within the range of 1 to 8192 pixels.

"Seed value out of range"

• Explanation: This error occurs when the seed value is outside the allowed range.
• Solution: Ensure that the seed value is between 0 and 0xffffffffffffffff.

"Density value out of range"

• Explanation: This error occurs when the density value is outside the allowed range.
• Solution: Adjust the density parameter to be within the range of 0.1 to 1.0.

"Blur amount value out of range"

• Explanation: This error occurs when the blur amount value is outside the allowed range.
• Solution: Adjust the blur amount parameter to be within the range of 0 to 1.0.
