Dimensional Room Mod
by Antara89
Dimensional Room adds keyed 3x3 portals that link private, chunk-sized pocket rooms in a separate Chamber dimension, so a player can step into a room from any linked portal.
What it does
Each keyed portal pairs with another portal of the same key, and the two stay connected across dimensions. Entering one portal from the Overworld brings the player into a private pocket room of chunk size, and the linked portal returns them to the Chamber. Portal surfaces and the dimensional-rift frame blocks are blast resistant, so the connections hold up against explosions.
Automation can use the same links. Hoppers move items through a portal, and Fabric fluid-storage systems transfer fluids such as water through it. Team Reborn Energy API systems can send FE and RF-style energy across the pair. A machine attached to a face that sits perpendicular to a portal surface sends its resources out through the matching face of the linked portal.
Installation needs Fabric Loader and Fabric API. Dimensional Room is client and server, so the server and every player need it. It is published for Fabric only, for 1.21.1 and 1.21.10, under All rights reserved, and it is not open source. The latest file, 1.0.10, is for 1.21.1.
Key features
Keyed 3x3 portals
Portals are built in a 3x3 layout and matched by key, so each pair connects only to its own partner.
Pocket rooms
Each linked portal opens a private room sized to one chunk, separate from the Overworld and from other players' rooms.
Item and fluid transfer
Hoppers and Fabric fluid-storage systems move items and fluids through a linked portal pair.
Energy transfer
Team Reborn Energy API systems send FE and RF-style energy from one side of a portal pair to the other.

Use cases
Who it’s for: Players who want a compact automation hub in a separate dimension, and server owners who want portal-based transport between bases on a Fabric server running 1.21.1 or 1.21.10.
How it compares
Stone Dimension is Fabric and client and server for 1.21.1, released under the CC0 1.0 Universal license and not open source. Pocket Dimension is Fabric and client and server for 1.21.11, under a Creative Commons Attribution Non Commercial 4.0 license, and it is not open source. Dimensional Room differs from both by covering 1.21.1 and 1.21.10 with a different license.
