Smoothing out Jagged Edges

[Shortliner]

So, I've been working on smoothing out the jagged edge of the cliffs of my route. However what ends up happening is that I use the smooth tool, and then I'd have to use the "snap to track" tool to bring the terrain back to the tracks, and the jagged edges would return. Does anyone have any hints or tricks in smoothing out the jagged edges?

Set Brush Width to 10.0, Brush Falloff to 0.3 to 0.5 and same for Speed, then adjust each point individually. The smoothing technique you're trying will work on lesser slopes but for the slope you show in the pic, one-at-a-time is your best (but slowest) bet. Lower the point to 45-60 degrees and raise up the notch between points and you'll get an overall reasonable slope that will look fine with foliage.

Yep - I do the same as Tori. Best results, albeit at a tedious pace.

Thanks Tori, I've been looking for this too.
