How do you toggle the buildable/unbuildable paramater for terrain?

I don't want to allow things to be built just anywhere--I need to alter the defaults. More specifically, I need the "Black Marble" and "Square Tiles" of the "Cityscape" terrain set to be buildable.

You can't, at least not natively in the editor. Someone else may have a way, however...

I tried altering the fields in the TerrainArt/Terrain.slk file and then importing it and restarting the editor, but it doesb't seem to be working.



UPDATE:

Altering the War3Patch.mpq's Terrain.slk file works! But having the copy inside of the .w3x file doesn't... :( Grrrr argh.

Well, I think Zepir's third-party editor may have been able to do it at one point, but it might not work any more.

Alternatively, you can re-import the textures you want over the file-path of some buildable textures you don't need.

Alternatively, you could change the buildings to require Ground-Pathable instead of Buildable, but they'd be able to be built underwater and on other un-Buildable terrain.
