Making Mountains in GIMP

[RobA]

I saw this post by Jurgen (at EN World) on making mountains in GIMP and figured I share a technique I worked out.

Hope the images all end up in the right order...

1. Make a shaky selection around the whole mountain. Keep the outline really ragged, not smooth:
2. Set colours for the base and peak of the mountain. fill the selection with a shaped angular gradient:
3. Duplicate that layer as a new layer and greyscale it:
4. Now stretch the contrast from black to white:
5. Apply a gaussian blur:
6. then apply a Filters->Noise->Spread to break it up:
7. Hide the B&W layer, and apply it as a bump map to the original coloured one:
8. Using a grungy brush and the colour of the mountain base, paint around the mountain (using the "below" brush setting)

9. and 10. Using Jurgen's grass and desert textures as backgrounds.

That's it... Hope it was helpful!
