Inputs (14)

Name	Type	Default	Description
image	IMAGE		Image to enrich with fractal Brownian motion.
seed	INT	00–18446744073709550000	Seed for the base noise generator.
base_noise	COMBO	simplex	Noise primitive accumulated by the fBm stack.
frequency	FLOAT	2.000.01–64	Fundamental frequency for simplex/perlin bases (acts as a multiplier for Worley).
feature_points	INT	161–4096	Base feature point count (used when base noise is Worley).
octaves	INT	51–12	Number of fBm layers to accumulate.
persistence	FLOAT	0.500–1	Amplitude multiplier between fBm layers.
lacunarity	FLOAT	2.01–6	Frequency multiplier between fBm layers.
distance_metric	COMBO	euclidean	Distance metric used when the base noise is Worley.
jitter	FLOAT	0.350–1	Feature jitter amount for Worley base noise.
strength	FLOAT	0.500–5	Scale of the normalized fBm field relative to the image's standard deviation.
channel_mode	COMBO	shared	Shared fBm field per sample or reseeded per channel.
temporal_mode	COMBO	locked	locked reuses the same fBm per frame; animated reseeds each frame.
maskopt	MASK		Optional mask (often image-sized) to limit the noise injection to masked areas. The mask is resized to the image resolution (bicubic when downscaling).
