The walkable height
The walkable height of the navmesh represents the height at which agents can walk under
objects. If multiple agents of different heights exist within the sandbox, the tallest height
should be used, as this will preclude any agents from bumping into overhangs. An adverse
effect of using the tallest agent's height might limit shorter agents from pathfinding under
objects they should otherwise be able to walk under.
A navigation mesh with a walkable height of 1.6 meters
The default height of our agents is 1.6 meters, as shown in the preceding screenshot. Note
how the overhang prevents navigation mesh generation within the area. If we generate a
new navigation for agents that are 0.5 meters tall, the area that was previously precluded
from pathfinding is now accessible.
