AI Driver Toolkit v3 Problem Waypoints

Unity Engine
1

Hello guys
I am using AI Driver Toolkit v3.
I am having some errors creating Waypoints.
When click “Press for new Waypoint” and then right click in scene view I am having this error:

ArgumentException: The thing you want to instantiate is null.

And also with other problem:

No container found. Place waypoints in scenes directly after pressing the Waypoint Editor button.
UnityEngine.Debug:LogError(Object)

UnityEditor.DockArea:OnGUI()

Hey folks, the solution is: You need a terrain!

No guys, the solution is that it doesn’t find the prefab, you have to modify the script called “AIWaypointEditorEditor” and then go to line 115.
Find your prefab directory (“…/AIDriverToolkit/Prefabs/Waypoint.prefab”).
Assign this directory to the directory of the line 115.
115. GameObject prefab = Resources.LoadAssetAtPath(“Assets/AIDriverToolkit/Prefabs/Waypoint.prefab”, typeof(GameObject)) as GameObject;
