The first question you should be asking is: what is a Blueprint?
The word Blueprint has more than one meaning in Unreal Engine. First, it is the name of a visual scripting language created by Epic Games for Unreal Engine 4. Second, it can refer to a new type of game object that was created using the Blueprint language.
There are two main types of Blueprints: Level Blueprint and Blueprint Class. Each Level of the game has its own Level Blueprint and it is not possible to create a separate Level Blueprint. On the other hand, Blueprint Class is used to create interactive objects for the game and can be reused at any Level.
