Thanks Doc, I had thought of WW but when I looked the site had gone, I assumed now that Denny et al have moved on the thing had died. Seems to be back up now but not sure about whether it is supported or not. May risk the $11 as their Apocalypse style would be an ideal basis.
@Voyager, cheers I have some roads done similar to that for 15mm but I am looking for a short cut for 28mm as my 2d painting skills are not really up to the detail effect I want.
