Converting a map from World Builder to Wilbur

[masdog]

Thanks to another post on this board, I found out about World Builder. I've been playing with the software, but I don't like the climate model that it generated after reading the Climate Cookbook. I'd like to import it into Fractal Terrains to see if it generates a better climate model, or baring that, a decent altitude map that I can bring into Photoshop to generate my own climate model. Everything I've seen shows that I need to bring the map into Wilbur before importing it into Fractal Terrains.

Unfortunately, I can bring the file into Wilbur, but I can't figure out how to generate an actual sea-floor or bump up the terrain to match the roughness that shows up in World Builder. It also comes in very blocky. Is there a good tutorial that explains how to do it? Does anyone have any tips for adjusting the height field?

I've included the output from World Builder.
