Origin is a plugin designed to help build a more immersive world that truly responds to characters’ backstory, traits, visual appearances and the events they’ve experienced. It streamlines the process of adding and managing properties such as traits, visual appearances and even their experiences. For example, if your character survives a bear attack, you can add an Origin that gives them a scar and makes NPCs react to their survival story.
Built in C++ and designed with flexibility in mind, fully exposed to blueprints means that its easy add to and extend yourself.
