NavMesh Extension v1.1.3
Requires Unity 4.6.9 or      higher.
Ever wanted to create a custom NavMesh, instead of tagging whole ob jects as static? Then this is for you! NavMesh Extension extends Unity's navigation system by an editor UI for drawing meshes, in addition to portals (teleporters), which intelligently search for shortcuts similar to off-mesh links (but better!).


Features:
* Complements Unity's pathfinding system
* Place vertices to create NavMeshes for agents
* Select and move multiple vertices at once
* Save your meshes as assets and prefabs
* Place portals to allow for shortcuts or    islands
* Find the shortest path through multiple portals
