After some explorations and carefully looking into the way Epic appears to want users to interface with Python in Blueprints, I have landed on a new modular way to integrate Python modules into Unreal which adheres to Epic's rules while reducing repetitive code.

Prefabs are an incredibly useful tool in the world-builders kit, and they’re incredibly common across studios and engines. None the less, Unreal doesn’t really have a true prefab system. So in this post we will look at developing a pseudo-prefab system using level-instance blueprints, Python, and Bluetilities.
