MultiWorld  1.0.0
MultiWorld plugin for Unreal Engine 4

Introduction

MultiWorld is a plugin for Unreal Engine 4 to handle multiple independent UWorld instances simultaneously. You can run several worlds in parallel, each one with completely isolated actors and components (and so with independent graphics, audio, physics, collisions, UI, etc), with the option to transfer the player and other actors between the worlds.
