Testing and visualizing the navigation mesh

In this section, we will explore some built-in tools to test and visualize the Navigation Mesh.

In particular, we will see how it is possible to visualize the navigation mesh under the hood and how the navigation test actor can quickly show us "the way" (the path generated by the pathfinding algorithm).

Visualizing the navigation mesh

As we mentioned back in Chapter 3, Navigation, when we generated a Navigation Mesh, for instance, by bringing into the map the Nav Mesh Bounds Volume, we also created a RecastNavMesh-Default actor in the level. If we select it, we can see many options there are to generate the navigation mesh, and some of them we already explored. However...
