Really awesome tutorial Arsheesh...though I have to admit I was pulling my hair out with Wilbur, mostly trying to get rivers where I want them. Just wanted to show what I was able to do. First, I started with a CC3 map I made for some folks on G+ just for kicks. I wanted to replicate this map, but give it a more realistic feel.
Obviously, you can tell its a CC3 map a mile away.
Using your tutorial, this was what I was able to do:
I'm really impressed with the results. Obviously, I'm still not done. For example, I'm going to have to manually add some rivers in the dark "blob-ish" swamp area in the south. The trouble I was having with Wilbur is that it wasn't making good rivers...it kept making these terribly short "wisps". My solution was to go back to Gimp and tone down the Land Clouds layer (reducing contrast) and doing a little more sculpting on the areas I wanted to force rivers. The only place it really didn't work was in the south swamp area, and the southeast peninsula where you can see a bit of a rut moving nw to se. Also, I probably should have spent more time beefing up my mountains, they look a little sparse and thin.
Anyway, I wanted to personally thank you for taking the time to make such an incredibly detailed tutorial. Any chance we can get your techniques on labeling? LOL, that's my next step.
Arsheesh, I'm trying to develop a specific technique for making cliffs using your method. I think it's working ok, but wanted to see if you've got a better technique. First my starting experimental picture.
Just a succession of gray colors in the general shape of a cliff, with a difference cloud layer mixed in.
Import into wilbur and run noise, fill, and precipiton results in this
Ignore the scraggly edges...just playing around. I think it looks ok, but the hard drop off causes weird color anomalies in the gradient map, i.e. the hard green line. I think I can utilize this for my mapping project, but wanted to ping you or anyone else on a different or better technique?
Oh...forgot to add, I used both the BUMP layer and an added emboss layer, both set to overlay. Played around with the transparencies until I got the "pop" I wanted. Merged them together when I was happy with it. On hindsight I think its perhaps a little too harsh.
I think I can implement this into your tutorial flow during the blending phase. Instead of blending directly onto the LAND BUMPS layer, use a transparent layer on top to do the blending. Then, you can cut a 'hard edge' on your cliff area, with a distinct light (top of cliff) and dark (bottom of cliff) transition. I'll see if it works.

Thanks Arsheesh. I'm still trying to figure this out. I've redone the map about 2-3 times, trying to get it just right in Wilbur. Here's the latest iteration:
No matter how hard I try, the swamp lands in the south start looking too hand drawn. Oh well...
My mind is blown at the moment...I think I'm just going to go with it, and start putting in the towns, etc.
Well perhaps the swamp-lands look a bit hand-drawn but I don't take that to be a problem. I think the map is really coming along nicely. You are doing great work.
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 with waterways
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).
