Multiple character selection

Hi guys just wondering I have a game where I want the player to be able to pick up to 3 characters out of 10 before entering a level. How would I do this via blue prints ? Also does that mean I need 3 player start locations in my map ?

Ok. This Tutorial is for multiplayer, but you can use a lot of it for your own Project. You do not Need 3 start Locations, but it is better. You can set the Locations like you want; Rotation, Location and so on. If you only have one Location, all character are spawned at this Location. Most of the time they clipping. Or not :o)
