Interface FilmGrainSettings

Noise amplitude, 0..1 (typical 0.02..0.15). Default 0.05.

Grain cell size in pixels (larger = chunkier grain). Band-limited value noise, so this sets a real grain scale rather than per-pixel sizzle. Default 1.5.

Tonal response, 0..1: 0 = uniform grain everywhere, 1 = the film curve (full grain through shadows/mids, faded out of the deepest blacks and the highlights). Default 0.8.

Tint each channel independently for RGB grain instead of monochrome. Default false.

Refresh the grain field over time (the "dancing" film look). When false the field is frozen — a single static grain overlay, useful for stills or a steadier look. Default true.
