Arbitrary Portals

About

Arbitrary Portals allows players to create nether portals of all different shapes and sizes, removing the needless rectangular restriction imposed by the vanilla game.

Usage

Build a portal frame in any shape you want (even containing holes), and then light it as normal! By default, the frame must be made of Obsidian, contain at least 6 blocks inside (like Vanilla's smallest 2x3 portal) and not be larger than 21x21 inside (Vanilla's maximum portal size)
All of these options are configurable! See the Config section below for more information

Shoutouts

While this plugin closely resembles Xisumavoid's "Custom Nether Portals" datapack, I actually started work on this months before he released his, and had the idea for years before that. Still, though, all of the Vanilla Tweaks datapacks are awesome and everyone should definitely check them out https://vanillatweaks.net/picker/datapacks/
