Spline Mesh Attribute

Note

Inherited from Generate Attributes — shares its anchor, alignment, and per-key transform channels.

Sweeps a Static Mesh into a USplineMeshComponent along the lane at the LengthOfSegment interval — ideal for guardrails, barriers, and curbs that must bend with the road. Add it and place keys with Attribute Mode.

Create new Attribute

Create a new attribute from the Content Browser under the Meta Road category:

In the Pick Parent Class dialog choose RoadLaneAttributeSplineMeshDescriptor:

Properties

Property	Description
StaticMesh	The mesh swept into a USplineMeshComponent along each segment.
BodyInstance	Collision settings applied to the generated spline mesh.
LengthOfSegment	Target arc-length [cm] of each generated segment (segment density).
Sampler	How the lane is subdivided — By Length of Segment or Between Keys.

For the shared per-key transform channels (Alpha, Scale, Offset, Roll, width overrides) and Alignment, see How a Generate Attribute follows the lane.

Drag and Drop

Drag a Spline Mesh attribute profile from the Content Browser onto a road lane to add it directly:

Examples

Sample assets: /MetaRoad/MetaRoad/Profiles/SplineMeshes.
