Inputs (32)

Name	Type	Default	Description
factor	FLOAT	1.000-100–100	Scaling factor for the generated noise of this type.
rescale	FLOAT	0.0000–100	When non-zero, this custom noise item and other custom noise items items connected to it will have their factor scaled to add up to the specified rescale value.
depth	INT	16	When non-zero, 3D perlin noise will be generated.
detail_level	FLOAT	0.00-10000–10000	Controls the detail level of the noise when break_pattern is non-zero. No effect when using 100% raw Perlin noise.
octaves	INT	2	Generally controls the detail level of the noise. Each octave involves generating a layer of noise so there is a performance cost to increasing octaves.
persistence	STRING	1.0	Controls how rough the generated noise is. Lower values will result in smoother noise, higher values will look more like Gaussian noise. Comma-separated list, multiple items will apply to octaves in sequence.
lacunarity_height	STRING	2	Lacunarity controls the frequency multiplier between successive octaves. Only has an effect when octaves is greater than one. Comma-separated list, multiple items will apply to octaves in sequence.
lacunarity_width	STRING	2	Lacunarity controls the frequency multiplier between successive octaves. Only has an effect when octaves is greater than one. Comma-separated list, multiple items will apply to octaves in sequence.
lacunarity_depth	STRING	2	Lacunarity controls the frequency multiplier between successive octaves. Only has an effect when depth is non-zero and octaves is greater than one. Comma-separated list, multiple items will apply to octaves in sequence.
res_height	STRING	1	Number of periods of noise to generate along an axis. Comma-separated list, multiple items will apply to octaves in sequence.
res_width	STRING	1	Number of periods of noise to generate along an axis. Comma-separated list, multiple items will apply to octaves in sequence.
res_depth	STRING	1	Number of periods of noise to generate along an axis. Only has an effect when depth is non-zero. Comma-separated list, multiple items will apply to octaves in sequence.
break_pattern	FLOAT	1.00-10000–10000	Applies a function to break the Perlin pattern, making it more like normal noise. The value is the blend strength, where 1.0 indicates 100% pattern broken noise and 0.5 indicates 50% raw noise and 50% pattern broken noise. Generally should be at least 0.9 unless you want to generate colorful blobs.
initial_depth	INT	0	First zero-based depth index the noise generator will return. Only has an effect when depth is non-zero.
wrap_depth	INT	0	If non-zero, instead of generating a new chunk of noise when the last slice is used will instead jump back to the specified zero-based depth index. Only has an effect when depth is non-zero.
max_depth	INT	-1	Basically crops the depth dimension to the specified value (inclusive). Negative values start from the end, the default of -1 does no cropping. Only has an effect when depth is non-zero.
tileable_height	BOOLEAN	false	Makes the specified dimension tileable.
tileable_width	BOOLEAN	false	Makes the specified dimension tileable.
tileable_depth	BOOLEAN	false	Makes the specified dimension tileable. Only has an effect when depth is non-zero.
blend	COMBO	lerp	Blending function used when generating Perlin noise. When set to values other than LERP may not work at all or may not actually generate Perlin noise.
pattern_break_blend	COMBO	lerp	Blending function used to blend pattern broken noise with raw noise.
depth_over_channels	BOOLEAN	false	When disabled, each channel will have its own separate 3D noise pattern. When enabled, depth is multiplied by the number of channels and each channel is a slice of depth. Only has an effect when depth is non-zero.
pad_height	INT	0	Pads the specified dimension by the size. Equal padding will be added on both sides and cropped out after generation.
pad_width	INT	0	Pads the specified dimension by the size. Equal padding will be added on both sides and cropped out after generation.
pad_depth	INT	0	Pads the specified dimension by the size. Equal padding will be added on both sides and cropped out after generation. Only has an effect when depth is non-zero.
initial_amplitude	FLOAT	1.00-10000–10000	Controls the amplitude for the first octave.
initial_frequency_height	FLOAT	1.00-10000–10000	Controls the frequency for the first octave for the this axis.
initial_frequency_width	FLOAT	1.00-10000–10000	Controls the frequency for the first octave for the this axis.
initial_frequency_depth	FLOAT	1.00-10000–10000	Controls the frequency for the first octave for the this axis.
normalize	COMBO		Controls whether the output noise is normalized after generation.
device	COMBO	default	Controls what device is used to generate the noise. GPU noise may be slightly faster but you will get different results on different GPUs.
ocs_noise_optopt	OCS_NOISE,SONAR_CUSTOM_NOISE		Optional input for more custom noise items. The following input types are supported: OCS_NOISE, SONAR_CUSTOM_NOISE
