So I'm working on making a nether plugin that will try to reproduce the SSP portals etc. I got it working up to the point where it scans for a matching portal in the other world and tries to create one, if there is none. I get the obsidian border of my portal, but trying to .setType(Material.PORTAL) on the blocks inside the portal doesn't have any effect, there's still just air, so the portals I create with my code do not appear "active". How to get this to work?
