Anyblock Portals
by wh0oo
Anyblock Portals lets a Nether portal frame be built from almost any block, once the block has been added to a whitelist.
What it does
Obsidian is normally the only frame material that lights a Nether portal. This mod extends that rule: a server operator adds full block IDs, including the namespace, to a whitelist, and a frame made from those blocks then opens a portal. The examples in the author text include pink wool, amethyst blocks and crying obsidian, and a single frame may mix whitelisted blocks with obsidian.
The whitelist is checked only when a portal is created. Portals that already exist keep working after the list changes, and removing a block from the configuration does not disable old portals. A portal that breaks must be lit again, and its frame then has to meet the current whitelist rules. Unusual-looking blocks can act differently inside a portal frame, and the author says anyone who uses them does so at their own risk.
The mod runs on the server only, so players join without installing anything. It is published for Fabric alone, with game version 26.2 as its only target, under the MIT License, and the code is open source.
Key features
Custom frame whitelist
Operators choose which blocks may form a portal frame, using full block IDs such as minecraft:pink_wool.
Mixed frames
Whitelisted blocks can be combined with obsidian in one frame, so the shape of a portal is not fixed to a single material.
Existing portals stay usable
Portals built before a block is removed from the list continue to work, while new portals follow the current rules.
Operator commands
Whitelist changes are made with commands that only server operators can run, which is the recommended route over editing files.
