+NavigationMeshes
|
|
|
+----------------
|
|
|
+
|
|
|
+Like all mesh instances, MeshLibrary items can be assigned a :ref:`class_NavigationMesh`
|
|
|
+resource, which can be created manually, or baked as described below.
|
|
|
+
|
|
|
+To create the NavigationMesh from a MeshLibrary scene export, place a
|
|
|
+:ref:`class_NavigationMeshInstance` child node below the main MeshInstance for the GridMap
|
|
|
+item. Add a valid NavigationMesh resource to the NavigationMeshInstance and some source
|
|
|
+geometry nodes below and bake the NavigationMesh.
|
|
|
+
|
|
|
+.. note::
|
|
|
+
|
|
|
+ With small grid cells it is often necessary to reduce the NavigationMesh properties
|
|
|
+ for agent radius and region minimum size.

|
|
|
+
|
|
|
+Nodes below the NavigationMeshInstance are ignored for the MeshLibrary scene export, so
|
|
|
+additional nodes can be added as source geometry just for baking the navmesh.
|
|
|
+
|
|
|
+.. warning::
|
|
|
+
|
|
|
+ The baked cell size of the NavigationMesh must match the NavigationServer map cell
|
|
|
+ size to properly merge the navigation meshes of different grid cells.
