My idea is that I want to use other mods, Portals 2 and CustomNPCs, to access the Nether, but also make it so the normal Obsidian Nether Portal Gate doesn't work. I want it to be accessed via a quest line only. I have the quest line worked out, and it does work, but can't prevent to the 'normal' method.
I found that nether=false doesn't help me, I can teleport there using the other mods, but can't see or do anything.
This leads me to believe it's something that has to be programmed via a mod.
What I think needs to happen is that generation/placement of the Portal Block needs to be prevented.
I have no clue how to do that, so I thought I'd ask here to see if 1) It's even possible, 2) someone might give me pointers, and/or 3) someone might even make a mod to do this.
ill have a play around with it but pretty much if someone beats me to it all that needs to be done is remove the recipe for the portal however that is done or block it so flint does not light the portal
