Creating a type of game that requires ai navigating at a further distance than is what is generated is impossible right now. This is important for moba style games where you need predictable ai moving along lanes. if players are too far away from ai they just dont move. thats if youre able to write a system that allows these ai to spawn, since spawners also dont work unless a player is near them.
Another issue is custom NPC local avoidance. there isnt any. custom npcs will walk into eachother and get stuck. we need the built in RVO support that unreal has.
ive solved ai spawning by writing a custom pooling script. i cant solve the ai just refusing to move because no navmesh is generated around them and i cant solve ai they get perma stuck on eachother because they cant avoid eachother. if we had the ability to bake the navmesh into the world at edit time it wouldnt ever need to be generated at runtime. if we could add RVO support to custom NPCs it solves local avoidance.
