The constant values in the compiler are wrong.
Use these values instead.

Caveats

  • This function has no effect if the script's owner is offline or not in the same sim as the scripted object.
  • This function has no effect if the scripted object is deeded to a group.
  • Playing with this command, I have found that the LAND_SMALL_BRUSH edits a 4m x 4m area. The LAND_MEDIUM_BRUSH and the LAND_LARGE_BRUSH, both edit an 8m x 8m area. However using 0 instead of LAND_SMALL_BRUSH will edit a 2m x 2m area. I have bug reported this, but until it gets fixed, it should be noted. correct values for the brushes are 0, 1 and 2, not 1, 2, and 3. - Bev
  • If the script is in a prim that is attached to an avatar or is in the child prim of a linkset, then the local position relative to it's attachment point or root prim is used rather than the position within the region. (BUG-4929)
  • If land is not owned by script owner or the owner doesn't have terraform permissions, the script will silently fail.
  • You cannot change altitude beyond land terraform limits for the specified parcel.
