I have largely been using a2area's Israh tutorial to do all my erosion up until now and I was happy with it. But now I've loaded the real world data into FTPro, I've realised my map's inadequacies.

These two images are at the same scale, projection and latitude.

They look like completely different scales to me. Evidently my map still has a long way to go before it's as natural-looking as the real world. But that is my aim.

So how do I go about eroding my planet to this level using Fractal Terrains 3 and Wilbur? I really want to do this. I am fully determined to make my erosion look that good.
