Sometimes there could be some gaps inside the scene that can make the navigation meshes disconnected. For example, our agents will not be able to find the path if our slopes are not connected to the walls in our previous examples. Or we could have set up points where our agents could jump off the wall and onto the plane below. Unity has a feature called Off Mesh Links to connect such gaps. Off Mesh Links can either be set up manually, or generated automatically by Unity's navmesh generator.
Here's the example scene that we're going to build in this example. As you can see, there's a small gap between the two planes. Let's see how to connect these two planes using Off Mesh Links.
