ZoneGraph Blueprint Tools – Lane Queries & Pathfinding in Blueprints

Use the full power of ZoneGraph directly in Blueprint.

Query lanes, move along them, read lane data, and generate paths between two world locations using a clean and gameplay ready Blueprint workflow. Every node is built with safe return values so your graphs stay stable even when no lane is found.

Perfect for traffic systems, vehicles, crowds, procedural placement, and runtime road logic.

ZoneGraph is extremely powerful and very Lightweight system, but most of its runtime workflow is locked behind C++. This plugin gives Blueprint users the same level of control all directly inside Blueprint.

Key Features

• Find the closest lane from any world position

• Get transforms by distance or normalized lane ratio

• Move across connected lanes through intersections

• Generate a path between two points on the ZoneGraph

• Read lane width, length, direction, tags, and profile data

• Query lanes inside an area

• Get linked lanes for custom routing logic

All designed for real production use with predictable and safe results.

Use cases

Traffic and vehicle systems
Crowd simulation
Spline replacement for large worlds
Procedural actor placement on roads
ZoneGraph debugging tools

Documentation & Example Map included

Each node is documented with Tooltips so you can integrate it into your project in minutes.

Important Note

This plugin works with ZoneGraph only.

It is not a Mass AI plugin and does not require Mass to function.
ZoneGraph is a separate lane based navigation system and can be used independently in your own gameplay logic, vehicles, traffic setups, or custom movement systems.

You can still use it in projects that also use Mass, but this plugin does not provide Mass processors, traits, or entity workflows.

Let me know if you find any feature missing that might be useful.
