Rob, I just had a thought, what if you use your top down mountain technique with the angular gradient fill, and then run this on top of the resulting height map?

I'd be interested in getting my hands on this, for just the reason Joe mentioned.
It does take a bit of futzing about.... Here is the result on the HF of the recent mountain tut I had posted.Originally Posted by jfrazierjr
The lines are a bit regular... adding some random to the code would probably help.

That is THE BOMB DIGITY!!!! As you said, if you can get some randomness into the "smudge stroke"(perhaps a displace???), this would be pretty much perfect.It does take a bit of futzing about.... Here is the result on the HF of the recent mountain tut I had posted.

Even if not, if I've got the outline of the mountains on a transparent layer, I can alpha to selection, then run a stroke selection or two with paintbrushes or erasers set to jitter or something to break up the lines and give it some randomnes, even if it turns out to be too difficult to add the randomness into the script itself.It does take a bit of futzing about....

Pimping my worldmap here. Still WIP... long way to go, but I'm pretty proud of what I've done so far...
OK, I rewrote it as a script and added a bunch of parameters.
Start with the defaults. It shows up under the Edit menu...
It works against a path, not a selection, so you will have to convert a selection to a path.
The only "weirdness" about it is that path slope is not differentiated by direction. here is a sample run on a circle to show you what I mean....
The top half stokes "inwards" first and the bottom half strokes "outward" first.
Depending on the pressure this might not matter, but it can be worked around by selecting inside the path (assuming it is closed) with a path to selection, running the script, then inverting the selection and running it again.
Have fun!

Wow. This could be cool. And I think, artistically speaking, I could imagine other uses beyond the mapping I wish to do with it - if I was inclined to be artistic with my computer.OK, I rewrote it as a script and added a bunch of parameters.

I already bumped you with my little rep-stick upthread. Wish I could give you more, but I'll have to spread some love first. Thanks a bunch, I think you saved me a month of work!
