Thanks guys , yeah i know its really cheap to buy but I kind of like knowing how to do these from scratch.(Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime)
Anyway will give both techniques a try although the write on method gives a pretty sharp edge to the transition and doesn’t look realistic so i think i will have to break out the old paint brushes from art school.
Cheers
Neil
