FluxLoading is a mod that enhances immersion by capturing a screenshot of the logout screen and displaying it when you reload your world. When you rejoin, you'll see the exact scene from where you left off, smoothly fading out into real-time gameplay.
What it does visually is as follows.
Before (world loading screen) 
After (world loading screen) 
FluxLoading does exactly the same thing as Seamless Loading Screen, a mod on higher versions. However, unlike Seamless Loading Screen, FluxLoading handles finer details, such as waiting for chunk generation before fade out instead of using a fixed delay.
