Parameters

Parameter	Type	Default	Range	Description
`scale` Scale	int	1	1 to 32	Increases the number of spots across the texture. Higher values make the pattern finer.
`background` Background Value	float	0	0 to 1	Initial grayscale value before any spots are accumulated. Zero starts from black; one starts from white. Independent of population strengths.
`positive_strength` Positive Strength	float	1	0 to 2	Amplitude of the positive-only hierarchy: one broad Gaussian layer and seven paraboloid layers.
`positive_size` Positive Size	float	1	0.25 to 2	Multiplies stamp dimensions for this population only. Placement count and centers remain unchanged; larger stamps increase coverage and overlap.
`signed_strength` Signed Strength	float	0	0 to 2	Amplitude of the broad, medium and fine paraboloid populations. Individual stamps randomly add or subtract.
`signed_size` Signed Size	float	1	0.25 to 2	Multiplies stamp dimensions for this population only. Placement count and centers remain unchanged; larger stamps increase coverage and overlap.
`grain_strength` Grain Strength	float	0	0 to 2	Strength of the fixed add, subtract, add composite of Gaussian grain at three frequencies.
`grain_size` Grain Size	float	1	0.25 to 2	Multiplies stamp dimensions for this population only. Placement count and centers remain unchanged; larger stamps increase coverage and overlap.
`subtractive_strength` Subtractive Strength	float	0	0 to 2	Strength of subtraction using the separately generated clipped-paraboloid spot image.
`subtractive_size` Subtractive Size	float	1	0.25 to 2	Multiplies stamp dimensions for this population only. Placement count and centers remain unchanged; larger stamps increase coverage and overlap.
`disorder` Disorder	float	0	0 to 1	Moves individual spots along continuous looping paths. Zero and one return to the same pattern.
`disorder_speed` Disorder Speed	float	1	0 to 4	Changes the distance traveled by the animated spots. Zero stops their motion.
`disorder_anisotropy` Disorder Anisotropy	float	0	0 to 1	Makes motion directional, with fading and additional spots to maintain the moving texture.
`disorder_anisotropy_angle` Disorder Direction	float	0	0 to 1	Direction of anisotropic motion, in turns. A quarter turn rotates the direction by 90 degrees.
`offset` Offset	vec2	[0, 0]	-1 to 1	Pans the tileable pattern. Moving by a whole tile returns to the same image.
`seed` Seed	float	0	0 to 100	Chooses a different repeatable arrangement of spots.
