I was just wondering if it is at all possible to use terrain for example badlands terrain with space terrain in the same map and still be able to use the map on b-net. maybe I'm just a noob i don't know. If there is some program that lets you or something like that  would some one please let me know. i have draft2 forge and x-tra editors. but i cant seem to be able to do it with those. Once again maybe I'm just a noob
and I'm not seeing what i need to do. thanks for the help people.

If anyone wants to know why i need this its because I'm working on a Final Fantasy 3-6 Rpg. Yes i know one or two are out there all ready but mine will be following the story exactly unlike the others and even more detailed using pics of the caves map and towns. yes i know i could just play the game blah blah blah but I'm doing it anyways it something i had 90% completed years ago when i first started  and i needed to format cant remember why but i couldn't save anything my computer. Anyways off topic yes i need it to use certain tiles that look more like building and snow covered mountains. i use Badlands now i need to use some of the ice world. or i will have to suffer with building that look like this "link below"
Anyways thanks again for the help and sorry for wasting your life with my jabbering and yes i know I'm not that far into it "yet!".

This isn't possible, I believe, as it requires an edited terrain file placed into an MPQ that would replace certain pallets of, say, the Badlands terrain with certain ones of the Space terrain.

I'm a little slow when it comes to the mpq files and what not sorry but say if i don't use every type  terrain would i be able to replace the ones that i don't use with ones that i need and still use the map on b-net.

Off topic here but i think i remember the max locations available is 255 either way is it possible to increase that.
i may have a problem since i need so many small locations all around the map. Just wondering but ill deal with it
when it comes up.
Thanks again!

No, any modifications to the tilesets would require an MPQ, to my knowledge.
