Omni Nav 3D is navigation for things that fly. Drones weaving through a city, jetpack heroes boosting across rooftops, dragons diving through canyons, gunships hunting down a target: Omni Nav 3D finds paths through full 3D space, around, under, over and through your level, not just across the ground.

Unity's NavMesh only knows about floors. Omni Nav 3D bakes the open air of your level into a compact sparse voxel octree, so flying agents know exactly where they fit, where they don't, and the smartest way through.

Fast enough for swarms. Queries and pathfinding run in Burst-compiled code, with A* and Lazy Theta* search and Quality, Balanced and Fast presets. A time-sliced scheduler spreads requests across frames with priorities, cancellation and callbacks, so dozens of flyers can plan at once without frame spikes. Paths are smoothed for natural, banking flight.

Flight that feels designed. Keep flyers inside a height band, steer them away from no-fly zones with cost volumes, make climbing cost more than diving, and give them energy budgets. Built-in avoidance keeps a swarm from colliding, and the flying mover handles the motion for you.

A living world. Moving obstacles and changing levels are handled with dynamic tile updates and non-blocking runtime re-bakes, so doors, bridges and destructible cover can change the airspace while the game runs.

Land and walk. Flyers can land on Omni Nav surfaces and follow combined walk-fly routes, perfect for jetpack heroes and creatures that switch between ground and air.

Set up in one click. GameObject > Omni Nav 3D > Set Up Scene fits a volume around your level, picks a voxel size, bakes it and places a flying agent. The Setup and Validation window checks your scene and fixes common problems. Missing Burst, Collections or Mathematics packages are installed for you.

See it in action. The Canyon Hero Showcase, a Feature Gallery with a station for every feature, a city-scale Stress Test, and demos for swarms, dynamic obstacles, height bands and zones, jetpacks and walk-fly hybrids. A complete PDF manual with API reference is included.
