EdgeAntiAliasing

The scene's edge antialiasing. Add it to an entity and the staircase along a high-contrast silhouette becomes a gradient, while the flat regions on either side of it are left as they were.

local id = entity.spawn("antialiasing").id
entity(id).component.add("EdgeAntiAliasing", { edgeThreshold = 0.125 })

Every field is live — editing one in the inspector changes the result on the next frame, and the values persist with the scene. Removing the last one in the scene clears the pass. antiAliasing.disable() turns the pass off where no component states it; while one stands in the scene, it brings the pass back.

field	effect
edgeThreshold	How much a pixel's luminance must differ from its neighbours', as a fraction of the brightest of them, before it counts as an edge.
edgeThresholdMin	The absolute floor under that test, which keeps the pass off dark areas.
subpixel	How strongly features finer than one pixel are corrected.
searchSteps	How far the pass walks along an edge looking for its end.

Lowering edgeThreshold catches fainter edges and costs more; raising it leaves softer edges alone. searchSteps is the other cost knob — it bounds how long an edge the pass can resolve.

One pass covers the whole frame, so one of these per scene is enough — the last one to push wins.

The work runs in fxaa.renderFeature; the settings live in @builtin::systems.antiAliasing.antiAliasing, which is also how to drive them from a script.
