Hello,
Is there a way to have 90 degree edge when flattening the surface. I always tend to get a sloped angle when flattening the terrain surface.. The image shows an example of what I am trying to do, maybe i am missing a setting or something for it.

You could try to remove the soft on the brush/ have your own brush calc but i believe there is a simplify mesh happening & it might not be possible without changing source
You can do it manually thru code, but thats a totally different story

You can't with the terrain, you'd have to use an Object for the platform.
