[Award Winner] Eriond - A Tutorial for GIMP & Wilbur

[Candacis]

Oh, yeah, I left the black border for now, because I probably want to make something there, not sure yet. But, of course, it is not part of the map.
Thanks for the feedback with the poles

I am working through this tutorial. I have just finished with the Wilbur section, and am starting on the Bump Map section. I couldn't get Wilbur to make a lake in the bottom left valley, so I figured I would add that later.
However, I cannot get GIMP to select just the rivers like he does in the tutorial. If I click towards the bottom of the rivers, it only selects up to that point. If I click further and further up it starts to highlight the entire coast, which I don't want either.
I can clearly tell where there are rivers and where there are not, so how do I get the program to do so?

Yes, this is a problem with the selection method I outlined in the tutorial: it only works up to a certain point. Another method which offers more precision is to create a separate (non-visible) layer which contains only the rivers. When you wish to make a river selection you can make this layer visible and use the select by color tool on the rivers. So how do you get this rivers layer? Well for that you need to load your height map back into wilbur, run "Fill Basins" (Filter > Fill > Fill Basins), and then apply the "River Flow" texture (Texture > Other Maps > River Flow). A popup menu will appear which allows you to select the color of the start and end points of the river (you will want to select dark grey and light grey for these) and adjust, via slider, the river length to be shown. You will also need to select the "Use Solid Background" box (which should be set to black by default). Click "OK" and this will output a Height map of just the rivers. Export this (as a textur .png file) to whatever map folder you are using for this project and then import it as a layer to GIMP. Voila.

Hello again arsheesh. I have some more questions:

I don't know what I did wrong, but I didn't notice any difference following the bump map stage. From what I have read it is supposed to be a big deal. Do you have any idea why? It doesn't look bad.

If I added the gradients and have then been fiddling with my rivers and lakes, is there a way to do the gradient over? Now that I have looked at it more I would rather it be changed; the colors don't sit right with me. I think you linked a tutorial about creating and editing gradients which I will read, but before I do, can I somehow remove your gradient?
