The Terrain Locator determines:
- the ground geometry on which to place Entities and to which the Entities will adapt their feet height
- the navigation mesh (static obstacles, borders of the environments, inaccessible areas...) that will be used during the navigation of Entities in a simulation.
Notice that, even if the navigation mesh is often computed from the ground geometry, those can be different if required. It is possible to use a rough geometry proxy to create a navigation mesh (will be faster to compute) and use a more detailed geometry as ground geometry. It is also possible to use the "Default Plane" navigation mesh mode if there are no obstacles in your scene (and even if your geometry has reliefs.

Ground to which the Entities will adapt during the crowd simulation. The available choices are:
|In Maya Geometry||Maya polygons used as ground geometry, when the Ground Type is set to Maya Geometry.|
|Dynamic Ground||If checked, the ground geometry will be recomputed at each frame (useful only if the input geometry is animated)|
|Double Sided||If checked, all the mapped geometry will be used as ground geometry, otherwise only the geometry facing up will be used|
Mode of the navigation mesh. The available choices are:
|NavMesh File||Navigation mesh file (gse file) to use in the crowd simulation and to display. The Navigation Mesh gile can be computed with the Navmesh Creator.|
|Obstacle Borders (red lines)||
if checked the locator displays the obstacles in the environment. If no NavMesh file is loaded nothing is displayed.
|Roadmap (orange lines)||graph linking all the accessible areas in the environment. If an area or a corridor is not covered by the roadmap, it means that it is not accessible.|
|Partial Borders (blue lines)||these are special constraints in the navMesh. They can be crossed by Entities|
|Free Borders (grey lines)||these are all the other edges in the navMesh that can be crossed by Entities|
|Navigation Cells (green lines and triangles)||all the walkable cells of a navigation mesh|
|Ground Geometry (dark grey lines and triangles)||the input ground geometry|
|Line Width||width of the lines drawn by the Terrain Locator|
|Locator Height||height difference to add to the lines drawn by the Terrain Locator|
