This is a very very bare bones mod. It adds flint and copper that can light regular nether portals again. However they light them by right clicking the two corners of the portal. They also support smaller sizes.
There are quite a few problems with the mod: The player will soft crash if going through these portals, they are just made for the trains, if on a train you will not crash but the player and any seated mobs on the train will fall of.
There is no plan right now to actully make this mod good so if anyone want to take over the project you are very welcome to.
