Any block portal

Any Portal Block

Choose which blocks can build a nether portal frame.

By default, nothing changes: only obsidian works, just like vanilla. Open the config and add any blocks you like, such as cobblestone, planks, wool, glass or gold. Mix several in one frame, or remove obsidian entirely.

How to use

1. Open Mods → Any Block Portal → Config
2. Edit Portal Frame Blocks: click + and type a block ID, e.g. minecraft:cobblestone
3. Build the usual portal rectangle out of any of your listed blocks
4. Light it with flint and steel or a fire charge

Changes apply instantly, with no restart needed.

Features

• Pick any number of frame blocks, and mix them freely in one frame
• Remove obsidian if you want portals to need something else
• An empty list disables nether portals completely
• Same portal sizes as vanilla (2–21 wide, 3–21 tall inside)
• Everything else stays vanilla: Nether travel, linked portals, particles, sounds, zombified piglins
• A misspelled block ID is skipped with a log warning instead of crashing

Config file

The setting is also stored in config/anyportal-common.toml:

portalFrameBlocks = ["minecraft:obsidian", "minecraft:cobblestone"]

Notes

• If you remove a block from the list, existing portals built with it break the next time a neighboring block changes, just like vanilla when a frame becomes invalid.
• Air, fluids, fire and portal blocks can never be used as frame blocks.
• Install on both client and server. The config screen is client-side, and the portal logic runs on the server.
