I'm new to the whole digital mapping thing, and I've been experimenting with Wilbur 1.78 over the last couple of days.

One of my favourite features is the "River Flow" map.

What I'm curious about is whether it is possible to export a plain background river flow map (so it only shows the rivers and none of the height map)? If so, it would come in awfully hand for the map I'm currently working on.
