# silt The abyssal plain's own material, on the `seafloor` shader. Ochre-grey silt sorted by a bottom current, with pale foraminiferal ooze on the crests and manganese nodules scattered through it. Every value here is the shader's per-pixel field rather than a texture: `ripple_freq` and `ripple_amp` set the fine ripple set, `trail_depth` the grooves something crawling leaves, and `probe_eps` the step the normal is differenced over. Worn by the `Seafloor` entity the abyss slice builds. Nothing else uses it.

# film The shared constants and the film clock for DEADLIGHT. Every slice of the demo reads this module and nothing restates its numbers. It holds three things: - The timing spine — the 14 shots, their durations and their windows. `Film.SHOTS`, `Film.shotAt(t)`, `Film.window(n)`, `Film.movementAt(t)`. Durations live here and nowhere else. - The world contract — the shared coordinate frame (`Film.WORLD`), the named entities each slice owns (`Film.NAMES`), the submersible's contracted path (`Film.SUB_PATH` / `Film.subPoseAt(t)`), the anchor fallbacks that let the film play while it is still being built (`Film.ANCHORS`), the palette (`Film.PALETTE`) and the water's optics (`Film.WATER`). - The clock — a fixed 1/24 s step advanced once per RENDERED frame by `deadlight.FilmDirector`, never from wall time. 2,256 rendered frames is exactly the 94-second film, every time. ```luau local Film = require("deadlight.film") Film.restart() -- t := 0, every slice resets, playing := true Film.seek(48.0) -- deterministic scrub to a moment Film.status() -- where the film is and who has joined it Film.register("abyss", { -- join from your own component's awake() reset = function() end, tick = function(t, dt) end, shot = function(n, tLocal) end, }) ``` Handlers run inside `pcall`, so one slice erroring cannot stop the film for the others. Registering a name twice replaces its handlers.
