NavMesh Areas can affect NavMesh generation and agent behavior/pathing.
The NavMeshArea component is used to define the location, shape and type of an area.
You can also specify the Area for a link component.
The NavMeshAreaDefinition resource is used to define properties of the Area.
- Currently there is a limit of 24 NavMeshAreaDefinition, but you can assign them to as many Area Components as you like
- Static areas are basically free.
- Moving areas are a bit more expensive, but you should be able to have at least a couple of dozens of them.
