Hey, not sure if I follow. ATBTT does not use the UE4 navmesh at all, but a custom pathfinding system. Is this what you mean by navmesh or do you mean the default UE4 navmesh? If you’re using my pathfinding setup you might want to look at the AI in the Sprint ability, where the AI prioritizes moving to tiles that have cover. Moving to tiles where they aren’t spotted would probably rely on similar logic.
