noise_warp

type: "noise_warp"

An animated value-noise field warps the picture in soft fluid patches; bright noise areas drag pixels the hardest.

Fields

Every screen effect also accepts screen_layer and the shared definition fields (duration, easing, loop, persistent, fade_ticks, sound).

Field	Type	Default	Meaning
scale	float	8	Noise cell detail across the screen (1..64)
amplitude	float	0.03 (fades to 0)	Max pixel offset in the brightest areas, screen fractions (0..0.25)
contrast	float	2	Gathers the warp into distinct patches (>1) or flattens it (<1)
coherence	float	1	1 = pixels flow along the noise gradient (liquid-glass), 0 = each patch pulls its own direction
speed	float	0.5	Field morph rate, cycles per second
drift_x/y	float	0 / 0	Pattern travel, screen fractions per second
