I need a multi world plugin for my bukkit server,, Minecraft version 1.3... I prefer the portals to the worlds be like a nether portal.. If anyone has one, and/or can link me to it and help me install it / set it up, I would appreciate it. Thanks!
I think Multiverse-Core is what you are looking for. They give a setup tut and it seems to be easy. Look it up!
MultiVerse and iGates should suit your needs. However, I'm not sure if iGates is working for 1.3.1 yet.
Does this work for tekkit or rather, If this was installed on a tekkit server could it be configured to have one world tekkit and the other a vanilla minecraft?
I doubt it, Tekkit and Vanilla are essentialy 2 different generators so No. you can't even connect to a tekkit server without tekkit... so what's the point?
