Terrain Sculpting
I don't know if anyone else is aware of this but I was having trouble shaping a peice of terrain using the usual tools when I had an idea.
Basically, in order to get the shape I wanted:
First I laid a road from the point I wanted to start, (The bottom), to the point I wanted to finish. (the top)
Then I added spline points where I needed extra features, like hollows and mounds.
Next, using the spline height tool, I set the spline points to the heights I wanted.
Then I used the smooth spline tool to make the ground rise up to the road.
Move the road to the next section, re-adjust the spline heights if necessary and smooth.
Keep repeating until the hill or slope is as you want it.
Delete the road.
It's fiddly and time consuming but if you're after a particular shape or working to an OS map, it gets you there. Another way around it is to create the hill or slope in the usual way and then use this method to sculpt the shape you want.
Hope its helpful.
