Chris: I am new to Unreal and I was wondering if you can use one blueprint for several actors. For example I would like for one blueprint to to operate multiple doors.
Hello and welcome.
You can have as much as components as you want in your blueprint. It will be one actor (the blueprint) but you’ll be able to do what you want with the components you’ll add in. You can have different doors in the same blueprint interacting with the others. Only thing is to be sure that this is the good thing to do . If doors are at the same place and, for example, one is closed when another is opened, then this is a good idea to have them in same blueprint. But if doors are separated in a maze without any relation then it 'll be better to do one blueprint with only a door and set this blueprint as much as you need.
Welcome aboard.
Hope you enjoy your stay.
