Hello! I downloaded a resource from the Unity store: Buildings_pack_light. They're just to mock up a scene and are some basic meshes with some textures on them. I have two of these buildings in my scene and when I apply a navmeshmodifier on them I receive multiple errors (one for each sub-component) "RuntimeNavMeshBuilder . Source Mesh does not allow read access: <object name>". In my situation I have used a NavMeshModifierVolume as the shapes are nearly rectangular, however in many situations this may not be the case. Thank you.
