Navigation mesh
This is required if you want AI to be able to move on your level, this includes using the function AI Move to
- In the Place Actors panel (Window->Place Actors If not showing), Search for Nav Mesh Bounds Modifier and drag it
Into the level
- Scale it up to the entire area you want AI to be able to move(Scale it up to the entire map if need be)
Generating the mesh
- After you scaled up the Nav Mesh Bounds Modifier, with it selected hit P
You should see something like the image below
If P doesn't work select the NavMesh object in the level directly
The red circles show how Big I scaled the navigation Bounds, just to make sure it covers the entire map
Bugs
If hitting P doesn't work than you have to select the navmesh Object in the level directly, selecting
it from the outliner doesn't work
