Generated from the shared modifier spec. Controls are optional; an omitted modifier stays disabled. See the format guide for examples, sampling cost and rendering units.

Signal distortion (`signal`)

Tear, stretch and shake the complete scene. Disabled under reduced motion.

Field	Label	Default	Range	Step	Meaning
`amount`	Amount	0.35	0 to 1	0.01	Overall distortion strength. Zero leaves the scene unchanged.
`shake`	Shake	0.25	0 to 1	0.01	Horizontal judder during a distortion burst.
`tearSize`	Tear size	0.15	0.02 to 0.5	0.01	Height of the bands that stretch and slip sideways, relative to the scene’s height.
`separation`	Colour separation	0.2	0 to 1	0.01	Separate colour channels around torn edges. Visible separation samples the scene three times; quiet frames use one sample.
`tracking`	Tracking	0.15	0 to 1	0.01	Brief vertical tracking slips during a distortion burst.
`frequency`	Burst rate	0.5	0 to 2	0.01	Burst cycles per second. Zero freezes the distortion while other layers can keep moving.
`seed`	Signal seed	0	0 to 100	1	Choose a different distortion pattern.

Pixelate (`pixelate`)

Display blocks in canvas pixels; their CSS size depends on devicePixelRatio and configureAurora pixelRatio.

Field	Label	Default	Range	Step	Meaning
`size`	Block size	8	1 to 64	1	Block size in canvas pixels. One leaves the scene unchanged; the CSS size depends on the rendering pixel ratio.

Vignette (`vignette`)

Darken the edges to draw attention into the scene.

Field	Label	Default	Range	Step	Meaning
`amount`	Darkness	0.45	0 to 1	0.01	Edge darkness. Zero leaves the scene unchanged.
`radius`	Clear radius	0.45	0 to 1	0.01	Size of the clear centre, relative to the scene’s shorter side.
`softness`	Softness	0.45	0.01 to 1	0.01	Width of the soft transition to the dark edges, relative to the shorter scene side.
