Currently i am testing a lot with World-Generations like the floating isand world i released a few days ago.
So i came up with an idea of creating a multiverse for singleplayer / multiplayer where the player spawns in a (currently ugly) lobby with lot's of portals.
Wich lead to:
-Overworld (without structures)
-End (citys and stuff, u know)
-Floating Islands (all biomes)
-Underworld (all biomes)
I want to merge all those worlds together with multiverse core. I had no problems to that stuff so far.
I'm having lot of fun with this.
But how can i prevent player to create netherportals? I don't want to disable flint 'n steel. Are there known methods for 1.15.2?
I'm not giving up my research on google but it's hard to find something useful.
