Client-side mod that allows you to add custom loading screens while you are transferred into another dimension

You can also add some text on the screen to display it to players

You might not notice them too much in a single player, but it will give you immersive sencses while playing on a modded remote server or modpack with a lot of mods

Note: new splashes are have to be placed into <game dir>/config/InterworldsSplashscreen/splashes

Some examples:

Overworld:

Overworld

Nether:

Nether

The End:

The End

For images above I've used the following image for Overworld and config:

"splashes files" {
    # Default splash to be used if not set for world [default: Overworld]
    S:defaultSplash=Overworld_water

    # Splashes images to be used in loading screen. Use just filename without extension. Files must be stored in folder splashes in mod's config directory [default: [Nether:Nether], [The End:The End], [Overworld:Overworld], [splashConnecting:Overworld], [splashDisconnecting:Overworld]]
    S:splashesPaths <
        Nether:Nether
        The End:The End
        Overworld:Overworld_water
        splashConnecting:Overworld
        splashDisconnecting:Overworld
     >
}

"splashes texts" {
    # Splashes texts to be displayed on splash [default: [Nether:Nether], [The End:The End], [Overworld:Overworld], [splashConnecting:Overworld], [splashDisconnecting:Overworld]]
    S:splashesTexts <
        Nether:A hot Hell filled with dangerous creatures
        The End:Far, far strange world filled with Endermans and the Dragon
        Overworld:Homeland of Lancelot
        splashConnecting:Overworld
        splashDisconnecting:Overworld
     >
}

Wanna use it it your modpack / on your server? You are free to use it, it's highly recommended for better world investigation experience!
