Two straight blizzard cliffs in map

I opened up a cinematic map someone made (link is below, quite big), played around with cliffs, as the map had 7 different cliff types, and got this.

How do I have two straight blizzard cliffs in my map? I've tried playing around with WEU's editor feature to change the cliff tileset, but I cannot seem to do it.

Only the two cliff-types true to the original terrain can be used. So, since your map appears to be Sunken Ruins as the base tileset, you should only use its two cliff-types. I forget there names now, but it should fix your issue.

I remember reading something, somewhere, about how you can use more cliff-types, but I can't recall. It really was a long time ago.

Well, that isn't a problem, since I plan to just import cliff textures anyway.

The problem is how to make a jagged cliff straight (which is done in the screenshot below).

I know one solution would be to import cliff models overriding the jagged cliffs, but that uses up a lot of space, and is tedious to do so anyway.

Ah, that's more specific. Unfortunately, I don't know how to help you with that. Is there a tileset with two of the straight cliffs?... I don't think so.

I was playing around with the map you linked, and the "straight" dirt cliff is stealing the model file from a "straight" cliff but stealing the texture from another. I don't know if it's possible to see two straight cliffs: I've never seen a map to-date with two straight cliffs. Now, if they hacked it (like using doodads with cliff textures on one side...) that's a different story.

Well, that would effectively be the same as having two straight cliffs in a map?

EDIT: Well, if it's not possible, I guess I should explain what I want to do.

I want to make some nice interiors for my map, but there are two types I need - stone, and wood. I have three options at this point:
1). Someone how get two straight blizzard cliffs in my map like how it's done in the map I posted, make one stone, the other wood.
2). Use destructables which use the cliff models for one of the cliff types. This doesn't seem like a bad idea now, but I don't like the idea of so many destructables...
3). Import models to replace the jagged cliff with the straight cliff. Probably the worst option.

What do you think?

I hope someone else can provide you with some better help, but I'd go with #2. I just double-checked and those glitchy (straight) dirt cliffs render perfectly fine and act like cliffs in the map (like in your screenshot)... So, if you can find a way to glitch it, then they seem fine to use.

The best variation should be to re-import a changed version of the sylk table.

"cliffModelDir" is "Cliffs" for normal cliffs and "CityCliffs" for the straight ones.
