Immersive Cursedness Updated Fork

This is an updated fork of TheEpicBlock's Immersive Cursedness.

Warning: This was only lightly tested on 1.20.1. There may be bugs.

Also, it supports block entities.

Woo-hoo!

Have you ever used Immersive Portals and thought this isn't cursed enough? Then this mod is for you! It uses advanced cursedness to deliver immersiveness straight to the client. And uses intelligent packet spam to ensure clients don't even have to install the mod themselves!

Disclaimer
This mod uses some questionable multithreading, whilst I'm relatively sure I don't use it in a way that causes issues, keep in mind that it hasn't been extensively tested.
