1. Create a project with placed props or a mesh terrain (height map terrains are now supported).
   
2. Launch the Generate NavMesh panel.
   
3. Choose one of the Range radio buttons:
   • Scene: All the mesh terrains and props will influence the NavMesh.
   • Volume: Only the mesh terrain or props contained in the volume will influence the NavMesh.
4. Adjust the settings in the panel.
   • Coverage Settings for NavMesh
   • Agent Settings for NavMesh
