Hello all,
I'm Faedother and I am new here. I have made dozens of maps for tabletop games and for minecraft servers. I just love making maps. However I wanted to take my map making skills to a new level. So I am trying my hand a realistic maps. So I looked up tutorials and found two I like, one from 2007 (Jeremy Elford Map Tutorials using photoshop and Wilbur) and one from here (arsheesh 's tutorials dealing with Gimp and Wilbur). However I ran into a problem with Wilbur. When I follow Arsheesh's tutorial, the Incise flow does not work. Here is my work flow;
I started by making a land mass and two islands and converting it into a black and white outline. Then I added Filter Clouds and did some work with brushes and Burn and Dodge to get this image.


Then I imported it into Wilbur and followed his instructions on how to create rivers and I get up to the Incise Flow part.


As you can see, Rivers appear in the preview and everything looks good. However when I hit Okay, nothing happens. This is all I see.


I have to do a Erosion Cycle in order to get rivers to appear.


This does not make sense to me. Well after that I export the height map.


Then I follow Jeremy's tutorial and I end up with this Image.



I think I am doing something wrong. Because the rivers are not coming up very defined and the map just looks too dark and somehow not correct.
If anyone could help, that would be great and thank you for taking the time to read this post.
Regards,
Fae

PS: My map is 5100x3300px at 300 Dpi
