I expand the tool circle to max diameter and adjust the sensitivity to control how quickly the terrain lifts. By keeping the circle moving I can raise the terrain into rolling hills without allowing one area to get too steep. Then I use smaller circles to adjust high and low spots to get the effect I'm after.
Klambert, Just a suggestion, but try this ...Load your dem into photoshop or similar...change to grayscale apply a gaussian blur.. value 1.8 to 2.0..varies, Save as a 24 bitmap..Should give even smoother hills? ..Regards.. ooops ..Very sorry Davesnow I just checked your excellent Mini Tutorial.. and saved a copy for future reference.. Yeah.. that's how to do it!!..Regards
