MultiWorld
It is the default world.txt file :
#This is the UltraBuild config file for worlds. #Define your worlds in which UltraBuild are enabled below: world=true AnotherWorldNameHere=true
For enable in a world you just have to add this : "TheNameOfYourWorld = true" or change true to false for disable UltraBuild in that world. And after you have to reload/restart your server.
