I want to use smart terrain related events code in my app.I imply followed "Smart Terrain Workflow in Unity" page content.
1.changed to samrtterrain by clicking the checkbox
2.AR Camera World center changed to SPECIFIC TARGET
3.Dragged PRIMARY SURFACE to the panel field which specifies World cnter for the above mode
Thwrite code or various eents of mart terrain.But here te first statement "using Pathfinding;" is failing to initialize.When I checked the page at "How To Use a Navmesh with Smart Terrain" , I have found that we need to Find the A* extension in the Unity Asset Store. And I have searched for that and find it was priced.Can you suggest any alternation,as I have imported 2D A* and it is failing.Earlier I have integrated ITrackableEventHandler successfully.I know how to use that predefined methods to catch events dynamically.but Thhis line of instruction manual is failing at the irst step itself.
