Lot Zone

UE 5.8 only

Lot Zone exists to tag Streets lots, so it ships with Streets in the UE 5.8 package only. See compatibility.

Lot Zone is a lightweight semantic actor. Its closed spline stamps a Name value onto every Streets lot whose centroid falls inside it. SA Get Lots emits that value as SA_LotZone for PCG filters and branching.

ControlWhat it does
Zone SplineClosed boundary. Edit its points with Architect Mode or the normal spline tools.
ZoneName written to matching lots, such as Residential, Commercial, Park, or Industrial.

When zones overlap, the smallest-area matching Lot Zone wins. A Lot Zone overrides a per-lot Streets setting; if neither supplies a value, the Streets Network's Default Lot Config → Zone is used.

After moving or editing a Lot Zone, rebuild the Streets Network and regenerate dependent PCG graphs. Lot Zones are metadata only: they do not directly create or remove road geometry.

PCG example​

  1. Draw Residential and Commercial Lot Zones over the network.
  2. Feed SA Get Lots → Lot Boundaries into Filter Data By Attribute.
  3. Filter SA_LotZone == Residential into one SA Spawn Building preset and the commercial branch into another.
