Hello there, this is the latest feature I coded for my open source project and it will be implemented, soon after some additions. This system, which is really close to the instance system in the newer chronicles, allows to spawn npc at different dimensions and travel there. This allows you to host multiple events at the same place at the same time, host multiple farm/pvp areas at the same place at the same time, and much more. Players and mobs cannot see another players and another mobs who exist at a different dimension.I am going to do some more modifications before I commit it. Here, you can leach an early version of it.
L2j dimensions
Here, you can find the diff patch for l2jpes and the modified .sql:

For those who are going to test this on a live server and they already have spawnlist installed, run this at your mysql command line:
alter table `spawnlist` add column `dimensionid` int(3) NOT NULL DEFAULT '1' ;
It is pretty similar with http://maxcheaters.com/forum/index.php?topic=279639.0.
