This is a small script-fu for the gimp that generates a rock texture based loosely on the tutorial https://www.cartographersguild.com/s...ead.php?t=4789.

Unzip the file and place the plugin in the `scripts` folder of your gimp2.8 directory (e.g. `$HOME/.gimp-2.8/scripts`).

Plugin: rock_texture.zip
