Terrain Deformations

Is there a way I can destroy permanent deformations? I'm trying to make a stomp spell where a crater is created and lasts 6 seconds. At first it looked easy, when I tested, it took 6 seconds for the crater to achieve it's full depth, then went back to the normal terrain height. When I set the deformation as permanent and duration to half a second, it seemed okay, but I can't find a way to "fix" the terrain and make it back to what it normally was.

Do the exact same deformation with reverse the depth number. This is not actully removing but overing it up, so this should leak.

:O Oh noes, is it bad when there are too many terrain deformations?

Malf ja sie sind voll sheisse.
never use terrain deforms... well IF and only for single player maps.

How/Why is it bad?

1) laggy
2) can cause desync in MP if use GetLocationZ()

u can do terrain deform in multiplayer ^^ If you deform point by point.

Guess I'm gonna have to trash this skill :|
