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

[waldronate]

The critical part of getting rivers where you want them with Wilbur is to have a mask with the rivers baked into it. Starting with your initial CC3 map, I made a few masks:


Coast


Coast with waterways


Hills


Mountains

The basic process was:
1) Load Coast as select, add 100 to altitude, then add a mound 50 high.
2) Load coast with waterways and add 100 to altitude.
3) Repeat for Hills and mountains.
4) Reload Coast as a selection to bound the erosion effects.
5) Now add noise with a value of about 25.
6) Fill basins and incise flow.
7) Now 25ish rounds of precipiton erosion to smooth things out.
A few more rounds of steps from 2 through 7 (you may want to adjust the maximum values to get slightly different effects).
