In this pack you can create realistic portals almost in any shape and size. It’s very similar like the original Portal game. You can find creative ways to use these portals, like you can create minigames, optical illusions, puzzle maps, and so much more. The possibilities are almost limitless.

The modpack also has all the 1.21.1. supplementary mods like Gravity Changer, Pehkui (Size Changer) and World Edit to enhance Immersive Portals mod even more.
