Hi, think the blueprint is an object in the world.
All meshes in it is his variable.
if he has so many meshs in it ,every time you reference to it will reference all mesh in it.
So good practice might be make them different blueprints.
That way you can control a door just reference to the door. Not the whole house.
but in my opinion you can use any method you feel like,there’s no a fixed way to do anything.
overthinking too much might cause you to be afraid of what you’re doing,and forgot what you want.
When it caused issues ,it will show.is what I want to say.
