I think there is some terminology confusion here, like you can see in the last attachment, there is no “spawn actor” in construction script. And “add child actor component” works when the actor is selected in the “child actor class” drop down, the problem was that i cannot acces this in the graph… But I found a workaround, instead of putting references of actors in an array to put them randomly in the child actor class slot of the add child actor component node. I now just added a add child actor component node per object i want to add (or spawn ;)) and use a switch on int node to randomize it.
