A lightweight mod that changes how you access the Nether. Building a portal frame from scratch won't work anymore, you must explore the Overworld, find a Ruined Portal, and repair it to ignite it.

No Craftable Portals: Lighting a self-built portal in the Overworld will be blocked, displaying an actionbar notification.

Ruined Portals Only: Nether portals can only be activated at generated Overworld Ruined Portal structures.

No Nether Ruined Portals: Ruined Portals no longer generate in the Nether.

Smart Relighting: Entering the Nether creates a single exit portal. If extinguished, entering from the Overworld will relight that exact portal. You can also relight portal that was generated when you entered nether.

This mod was tested and developed specifically for a custom modpack. While functional, full compatibility across all third-party mod setups is not guaranteed.
