Immersive Portals (Forge Port) with gravity support reintigrated finally, works with the forge portal gun addition too if you wanna get that one :3
Based from: https://modrinth.com/mod/immersive-portals-neoforge but with gravity again like it's Fabric port has had for a long time. I BADLY wanted gravity to work so I took the past week (01/06/2026 to 06/06/2026) learning Intellj and spotting out the differences so I could reconnect it myself. Those who want trippy gravity effects again but forge, Enjoy ^w^
Thank you to Tfarcenim for building GravityChanger onto Forge !
