World editor questions

So,
i got it running and added a place and an npc to my local shard...

now i'm trying to add a portal or stuff like it...

anyone out there got a clue what

pacs_trigger_id could be and where to find it?

Hi, I got everything compiled. What is the next step to get things up and running and using the world editor?

Well...
there are one or two articles in the wiki...

i gather all the stuff i'm using and my own clues in this article:

ok,
found this:
pacs_trigger_id : . This is the trigger id given by the 3D team. It identifies the trigger physically on the landscape

so now... where is a 3D expert who can give me a clue about this?
