Hey all,
I'm trying to figure out how to make a sliding, horizontal door similar to those found in MP3's pack, only much, much larger (4x longer, 2x taller, and preferably sliding apart in both directions, rather than just one way).

Is there a brief, simple way to do this (for a noob at modding like myself) or is it something I should just request and leave up to the pros?

templates contains the template file of a door.
tutorial contains the tutorial on to how to make a door.
so basicaly take a door template make some basic .ini changes(change a few sizes) and edit the template sprites to the sizes you want.
did you bother to search/look for them?
they are on the first page of the mod making thread...

Sorry - didn't have the slightest idea of what to actually look for.

"Making doors" doesn't pull up a whole lot of useful data on this particular topic in the search field.

anyway as long as theese help you.
try messing with them for a while and post only if you have a big time problem
