Hello everyone! i would just like to ask a kinda complex question but if someone can help me out that would be great! i am trying to create a randomized NPC spawn for a game im planning to make and what im trying to use this for is for dynamic battle events and randomized camps/city spawns. i need this because im trying to create a space game and i wan’t planets inhabited with city’s and npcs and battles you can stumble across. But i have no idea how to do this! i know this is a packed question and most wont know how to answer this but if anyone can lead me in the wright direction it would be much appreciated :slight_smile:

P.S i preferably use blueprints
