Making Holes in the terrain ?

Unity Engine
1

is there any way to make holes in the terrain, for example fade it out using a texture with 0 alpha, and paint it onto the terrain ?
Will this work ?

2

set height and lower it.

no you can’t paint holes into the terrain

hmm, lowering the height doesnt work… already tried it…
I have a high plateau… but you can look/fall off, and see that its just a big square…

thanks for the idea though

Try fog to hide the far bits.
