Curb Cut Attribute (Pro)

Creates curb cuts (dropped curbs) on sidewalks — the lowered ramp where a sidewalk meets a crossing or driveway. It reshapes the sidewalk’s curb procedurally at each key position. Can only be added to sidewalk lanes.

Properties

Property	Default	Description
`bIsCross`	off	Symmetric “cross” cut. When on, only the begin width/falloff are used and `WidthB` / `FalloffB` / `Alpha` are ignored.
`WidthA`	200 cm	Width of the cut at its begin.
`FalloffA`	50 cm	Falloff (blend distance) at the begin.
`WidthB`	200 cm	Width of the cut at its end (when `bIsCross` is off).
`FalloffB`	0 cm	Falloff at the end (when `bIsCross` is off).
`Alpha`	0.5	Lateral position of the cut’s end across the lane width [0.1 = inner edge … 0.5 = center … 1.0 = outer edge] (when `bIsCross` is off).
`MeshDensity`	4	Subdivision density of the generated cut mesh [1–10].
`bSmooth`	off	Smooth (rounded) rather than sharp transition.
