The maximum height difference between two areas for navigation to be generated between them. The maximum angle a slope can be at for navigation to be generated on it. The size of cells in the [NavigationMesh]. The physics layers used to generate the [NavigationMesh]. What kind of geomerty is used to generate the [NavigationMesh]. Which geometry is used to generate the [NavigationMesh]. The name of the group that is used to generate the [NavigationMesh]. The number of vertices to use per polygon. Higher values will improve performance at the cost of lower precision. If two adjacent regions' edges are separated by a distance lower than this value, the regions will be merged together. The minimum size of a region for it to be created.
