Dynamic Dimensions
by 6oundwave
Dynamic Dimensions lets players build a portal of any block type and light it with Flint Steel to reach a dimension generated entirely from a chosen material.
What it does
A standard 4x5 portal frame can be built from a block of the player's choice, such as iron blocks, and lit with Flint Steel. Frames made from other blocks work the same way as the vanilla obsidian frame, which still opens the vanilla Nether portal. Stepping through a lit portal takes the player into a dimension whose terrain is generated from the material that was used to build the frame.
The mod uses its own lightweight portal logic rather than relying on a separate portal API. Mods that substantially change how Flint Steel works or how portals are detected may clash with Dynamic Dimensions, and the author observes that display problems caused by other portal-handling mods can keep a portal from lighting. Optimization mods that aggressively cull rendering are generally safe, since they rarely glitch portal textures. The mod is client and server, so the server and every player need it. It is released under the MIT License, and files are published for Fabric only, for 1.20.1.
Key features
Any-block portal frames
A standard 4x5 frame can be made from a chosen block, so portals are not limited to obsidian.
Material-based dimensions
Stepping through a portal enters a dimension generated entirely from the material the frame was built from.
Flint Steel activation
Portals are lit with Flint Steel, and the vanilla obsidian frame still opens the regular Nether portal.
Self-contained portal logic
Portal handling is built into the mod instead of depending on a separate portal API.

Use cases
Who it’s for: Players on Fabric 1.20.1 who want portals built from different blocks, and server owners who want the same portal setup for every player.
How it compares
Steel and Flint is a Fabric mod for 1.20.1 that is client and server and is not open source, with an All rights reserved license. Ethrilic Dimension is server-side only, Fabric only, for 1.21.8 – 1.21.11, and is also not open source under All rights reserved, so players can join without installing it. Better Nether Portals covers Fabric, Forge and NeoForge for 1.20.1 – 26.3 under All rights reserved, which makes it the choice for a wider loader and version range.
