Curb Profile

A Curb Profile (URoadCurbProfile) defines the curb cross-section — its shape, width, and material — for sidewalk lanes (RoadLaneSidewalk). You set it once as an asset, reference it from a sidewalk lane, and the curb is generated along the lane’s edge during baking.

A Curb Profile asset

Create one from the Content Browser (right-click → Meta Road → Curb Profile) and edit it in the standard Details panel — it has no dedicated editor.

Description

CurbCurve

—

The curb’s cross-section silhouette, as a float curve. Its input (X) runs across the curb — X = 0 at the sidewalk-side back wall, increasing toward the road up to Width — and its value (Y) is the height at that point. Needs at least two keys, or no curb is generated.

Width

15

Curb width [cm] — the lateral extent the CurbCurve X axis is mapped onto.

DefaultMaterial

—

Material applied to the generated curb. A sidewalk lane can override it per lane.

The CurbCurve is where the curb’s shape lives — edit it in the curve editor in the Details panel. It starts at X = 0 — the back wall on the sidewalk side, at full height — and moving toward the road traces the curb’s flat top and face, then ends sharply at Y = 0 where it meets the road.

The CurbCurve maps lateral position to height. X = 0 is the sidewalk-side back wall at full height; moving toward the road the silhouette drops down the curb face and ends sharply at Y = 0.

How it’s used

  • A sidewalk lane references a Curb Profile; the curb is built along that lane’s edge at baking.

  • The profile’s DefaultMaterial is used unless the lane overrides the curb material (Override Curb Material).
