MultiWorld Version 1.1.0: https://www.unrealengine.com/marketpl...
You can now change the Active World playing a nice and customisable visual transition effect. The system uses an ordinary Unreal Engine material to mix the source and destination worlds, so it's very easy to create your desired transition effect.
MultiWorld v1.1 is now able to capture scenes from Background Worlds, with custom versions of SceneCapture2D actors and components. You can then use the render targets as you prefer.
