    I'm not sure I quite understand how to glow the borders like you described, but I'm guessing this mega blur thing yields bolder edges than other blurs and I need to use layers and opacity?

    Anyway, pertaining to the terrain stuff, the issue I'm having isn't generating terrain - I'm already able to do that easily with Fractal Mapper 8. It's generating topographic lines (not shapes) for rivers and borders in GIMP or Photoshop.

    I was waiting for something so I knocked off a few images. This is for the rand terrain. Ok so its quick and dirty and the amounts of noise need to be tweaked down a bit cos its a bit over the top. I'll do the glow in a mo...

    Heres quickie steps. Start with some terrain, generate glow colored version, blur it a lot, select original land and paste on top. Again, this is my super quick attempt and probably needs more finesse but thats it basically.

    Oh, I see. Actually, I was looking to make the glow to be inside the borders like in the picture I linked, not outside. That's why I was confused.

    Same process but cut out the sea and paste back on instead of the land so that the glow goes into the land instead.

    I think you need to do this on layers and mask each region out one by one and add in the glow a little at the end. But yeah its basically take the shape, blur it, mask out off the shape so that your left with just the blur that went into it and put in as a layer. Maybe multiply it with a constant color like red to get a red glow.

    This can be done in PS, and quite easily too. I stumbled upon it while experimenting in my secret lab last year. Filter-render-clouds (pic1). Filter-artistic-cutout. Filter-stylize-find edges. It produces what you see in pic 2; looks like contour lines. Even easier, is what's in pic 3, same clouds but then Filter-stylize-trace contour; makes a continent outline.

    I really hate to sound like I'm beating a dead horse, but making continents was never a problem thanks to FM8. What I need is to be able to draw a line in GIMP or Photoshop, and then have it becoming 'fractaled'.
