(deforum) Noise Parameters Output Parameters:

output_image

The resulting image after the specified noise has been applied. This image will have the same dimensions as the input image but with the added noise effect, providing a new texture or pattern based on the selected noise type and parameters.

(deforum) Noise Parameters Usage Tips:

• Experiment with different noise types to see how each one affects your image. Each noise type has unique characteristics that can dramatically change the visual outcome.
• Use the amount parameter to control the intensity of the noise. Start with a lower value and gradually increase it to see how it impacts your image.
• For reproducible results, set the seed parameter. This is particularly useful if you need to generate the same noise pattern across multiple images.
• Adjust the specific parameters for each noise type (e.g., num_points for Voronoi, scale for Simplex) to fine-tune the noise effect to your liking.

(deforum) Noise Parameters Common Errors and Solutions:

Invalid noise type selected

• Explanation: The selected noise type is not supported by the node.
• Solution: Ensure that the noise_type parameter is set to one of the supported values: wavelet, value, flow, turbulence, ridged_multifractal, reaction_diffusion, voronoi, or simplex.

Parameter value out of range

• Explanation: One or more parameter values are outside the allowed range.
• Solution: Check the minimum and maximum values for each parameter and ensure that your input values fall within these ranges.

Missing input image

• Explanation: The input image is not provided or is in an unsupported format.
• Solution: Ensure that you provide a valid image in a supported format as the input.

Seed value too large

• Explanation: The seed value exceeds the maximum allowed value.
• Solution: Ensure that the seed parameter is set to a value between 0 and 2^32 - 1.
