looking for a program...

I'm looking for a program or some way to easily edit water height levels. I can raise and lower water by abusing advanced -> enforce water height limits, but it's fairly tedious to get an exact height (it usually likes to scale to cliff heights) and it ruins any nearby terrain by resetting regular height levels. This is somewhat annoying because after I have the general shape of the terrain ready and then bring up the water it already undoes my terrain once, and unless I get the water in exactly the right places the first time, I end up having to redo everything again because it gets messed up when I have to remove or add any more water...

I'm pretty sure that water vertices can be individually modified because I tried Zepir's map editor (wc3sear.ch) and it lists the water height for each vertex, but I can't figure out how to get the editor to either work or just not corrupt my map. I'd gladly settle for manual editing in a text file or something but that's not working out either. I think the terrain file is the .w3e since it has tile information all over the place (Ldrt, etc), but aside from that information all notepad can read is the little square boxes and whatnot. If you could edit it all manually you could end up with some pretty neat stuff like rolling hills of water or what have you...not what I want, necessarily, but the ability to do it would make my regular terraining much easier...

So yeah, anyone know what kind of program can open .w3e (if it even is that) or whatnot?

edit: I figured this probably goes here but if it belongs in the terrain forum or somewhere else instead please move it for me =)

You're right, the info is all in the .w3e file.
There's no program that would automate what you're trying to achieve so get a hex editor to open and edit the file.
Here's the
file format specs for the file.
Check out the water and water height flag for each tilepoint (32 x 32 cell)

Thankyou very much =)
