<description>
Bakes navigation data to the provided [param navigation_mesh] by parsing child nodes under the provided [param root_node] or a specific group of nodes for potential source geometry. The parse behavior can be controlled with the [member NavigationMesh.geometry_parsed_geometry_type] and [member NavigationMesh.geometry_source_geometry_mode] properties on the [NavigationMesh] resource.
The bake function is deprecated due to core threading changes. To upgrade existing code, first create a [NavigationMeshSourceGeometryData3D] resource. Use this resource with [method parse_source_geometry_data] to parse the SceneTree for nodes that should contribute to the navigation mesh baking. The SceneTree parsing needs to happen on the main thread. After the parsing is finished use the resource with [method bake_from_source_geometry_data] to bake a navigation mesh.
