Yes, I think too they need to be side by side. Dunkel, don't forget to tell us if you get any good. I'll experiment more tomorrow too. I'm pretty confident we can get reasonable looking rivers with widths less than 50 m, but the question is to find a good method such that we don't spend ages doing that for each 1000 meter length of such rivers...
Ashes and 2bits I think you got something like 100 meter wide rivers using the 3 pixel soft pencil?
