I realise this is a bit of a noobish question... but how how do I spawn an actor when a certain stage in a quest has been reached. I'm trying to make a dark brotherhood-esque assassination quest, I want an npc to appear when, and only when I've been given the quest.
I've fiddled about with aliases, trying to get them to create npcs at certain locations (which works) but so far I cannot get them to spawn when the quest is initialised.
