Okay, so I do the Munge thingy, I open Battlefront, and it tells me it couldn't open the map. Shouldn't the map the tools made for me work? What do I do?!?

What did you edit? And post your munge log. We cant just go off wondering what you did, because that an infinite number of things that are possible that could cause your crash.

Munge log? You mean the word pad thingy that shows up?

That would be it, yes.

Hang on, I'm re-munging as I type this......

Don't doublepost, especially just 4 minutes apart. -Staff
Edit:
Gotcha!

Why were you editing the ambush scirpt?

Also unless you are changing the sides, sounds, localiztion and shell the only thing you need to check on a munge is common.
Try doing a clean of everything then munge with only common checked.

Ambush script? I just hit "select all". And what does it mean to "clean"?

I'm a n00b aren't I?

You have a munge and clean button. Clean erases all the munged data.

Now I got the map working, but when I place objects and save, they won't show up!

Well, when you add them, do you munge?

Oh...

and where are the mshs and odfs of the objects placed?
they have to be in your \data_XXX\Worlds\XXX\msh or odf folder (you have to create the folders)

In order for anything to work you must munge.
