How do i assign the AI Controller to them after Spawning
do your characters not have a ai controller by default? if they arent acting as they would if placed in the level then it may just be the ai default possession, basically theres a option that you need to set to “spawned and placed in level”, i odnt have unreal open at the moment so i cant say the exact option but itll be in the class defaults list 2 options below auto posses player.
how can i find a connection from the array to Skeletal mesh target
again something you shouldnt need to do, but the way you could do it if you choose to go that route would be to use a for each loop on the output array then get the skeletal mesh component off the blue array element pin on the loop. depending on your setup you may also need a cast in there to define which class your looking for (cast to character or your specific character class type)
