TemporalAntiAliasing

The scene's temporal antialiasing, authored and persisted.

local id = entity.spawn("antialiasing").id
entity(id).component.add("TemporalAntiAliasing", { historyWeight = 0.9 })

Every field is live: editing one in the inspector re-pushes it, and the values persist with the scene like any other component.

field	effect
historyWeight	How much of the accumulated result to keep each frame. Higher resolves more detail and settles smoother, at the cost of taking longer to let go of what a surface used to look like.
neighbourhoodClamp	How far outside the neighbourhood's own colour spread an accumulated sample may sit before it is pulled back in. Lower rejects more, trading some of the settling for a result that follows change faster.
sharpness	How much of the edge lost to averaging over sub-pixel samples is added back. 0 leaves the accumulation as it is.
motionRejection	How much fast motion shortens the memory, which is what stops a moving object trailing behind itself.

What the pass does with these is in taa.renderFeature's README; the runtime API is @builtin::systems.antiAliasing.temporalAntiAliasing.
