NavWorld is Unity 6.6’s way to query a NavMesh from a job. This video covers what that handle actually is, how it picks up the surfaces and links you already loaded, and why CalculatePath on the main thread stops scaling. Then we build a job around GetDefaultWorld and a NavQueryBuffer: map a start and an end, search in slices, and read back whether the point is reachable plus the points to get there.
This approach is ideal for developers looking to scale AI systems or handle complex navigation requirements without blocking the main thread. Implementing multithreaded pathfinding ensures your game logic remains responsive while your agents calculate their routes.
