Hi, it seems that FallOff at Scale is behaving non-standardly. If FallOf is set to "0" at Scale for Include, it still changes the objects/trees. If I set FallOff to a small number the trees are slightly larger, but still shrink. For Exclude, everything works as it should. Density also works correctly.
Edit: The problem arises when I want to use FallOff only for Exclude. Even though I have set "0" for Include, the trees still shrink at the edges of Include. :-(
