Chevron Marking Tool (Pro)

Note

This is the Chevron tile in the Create palette of the Meta Road editor mode (see The Meta Road Editor Mode). (Pro feature.)

The Chevron Marking Tool draws chevron guide-island markings — the striped “V” islands painted at gore points where traffic flows split or merge (for example at off-ramps). The marking is a spline-driven UChevronMarkingComponent added to the selected road actor, and it participates in baking together with the road surface.

Requirements

Select one actor that contains a URoadSplineComponent before activating the tool.

Drawing a chevron island

1. Select the road actor and activate the Chevron tile.

2. Click in the viewport to append a sharp (linear) point to the island outline. A live preview of the chevrons renders as you go.

3. Click-drag to reposition the last point.

4. Accept to commit the UChevronMarkingComponent to the selected actor, or Cancel to discard.

At each interior point of the spline, the point is the apex of a wedge between the two tangent directions; the wedge is filled with chevron V-bands pointing outward. Open-spline endpoints are skipped.

Properties

Component-wide (the component’s Details panel):

Property	Default	Description
Section Size	100	Depth of one chevron band (the “V”) along the wedge bisector, cm
Section Interval	200	Gap between consecutive chevron bands, cm
Road Zone	—	Road surface type (material/color) applied to the marking
Texture Angle	0°	UV texture rotation, in degrees
Texture Scale	1.0	UV texture scale multiplier

Per-point (in the spline’s Selected Points section — select one or more points first):

Property	Default	Description
Draw Chevron Marking	off	Generate a chevron island at the selected point(s)
Size (cm)	1000	Island length along the wedge bisector, in cm — drives how many chevron bands fill the island
Offset (cm)	0	Distance from the node where the chevrons start; shifts the whole Size region away from the node (drawn region = [Offset, Offset + Size])
Reverse Direction	off	Flip the chevron pointing direction — toward the node apex (off) or the wide end of the island (on)

Next steps

• Bake to generate the marking mesh together with the road.
