So I've finally managed to put together a tutorial for the method I've started using to make cobblestone streets. There is an example in this forum thread: http://www.cartographersguild.com/vi...hbourhood.html. I couldn't get the file size down on the pdf, so I've put the pdf and the files I used (including Illustrator and Photoshop brushes and some Photoshop styles and patterns) up on Dropbox.
The tutorial pdf is here:
I've divided the additional files into three parts so that you don't have to download a pile of stuff you don't need:
The example .psd file
Photoshop brushes, patterns, and styles
SVG files for InkScape
The InkScape items are only a little bit useful, I will update with some better documentation and files for InkScape soon.
This tutorial was made when I used older versions of Photoshop and Illustrator, but I've included my settings in the pdf so hopefully GIMP users and users of newer Adobe software can get something out of it. I also converted my Illustrator brush files to SVG which I'm led to believe might make them more useable for Inkscape users.
I have never really produced an instructional document before, let alone a mapping tutorial, so I would be happy to hear feedback about the tutorial itself as well as (dare I hope) if you find it useable.
Edit: I finally got the final part of the tutorial included. The link is the same but I've added a few pages at the end of the tutorial covering my method for getting moss to grow on the cobblestones.
I finally went back and reduced the file size of the pdf, so if you don't want to mess with DropBox you can just use the attached version of the tutorial document. I have also attached some of the brushes and textures I used, though the .psd file itself is too large to attach. Just a note: the quality of the images in this smaller .pdf is not great, but I think everything is still legible. The version on DropBox has clearer images.
