A few WorldEdit questions

I have a few questions, since I'm making a campaign all on my own (except for the Cinematic levels, which I need help with, and would like someone else to do). First of all, I want to make the main villain dude/last boss to have the transformed Demon Hunter model file, only whenever I base it off of Illidan in Demon Form, it just uses the Evil Illidan model. And, whenever I put maps into a campaign, it says that the maps aren't active. What do I do? And, how do I make it so a trigger only happens when a unit owned by a certain player happens? And, (lots of ands) how do I put down subtitles when I'm not using cinematic mode? And how do I make ALL of the units owned by a certain player move automatically to a Region once a trigger starts. And how do I make Guard Tower, Cannon Tower, and Arcane Tower models work on custom units. I need some help here people. Please help me, I'm just an innocent child.

For the Demon Hunter to be constantly in demon form, go into the object data for your custom unit, look for an entry named "Art - Required Animation Names" enter "alternate", and Presto! That should work if my memory serves.. I can't help with your other questions though :(

For the moving all units of a player to a region do after the events in the trigger

Actions

Take all units in unit group (group is units owned by the player) and do action..

move picked unit to region


And poof! they move! hahahaa!!
