Does anybody know of a way, either by writing a shader or by some other jerry-rigged means, to take a map that is built from physical hex's, like my prototype below....
and overlay an effect that would add a painterly grunge which sort of blurs it all together to get something akin to this:
Now I understand that this map from Total War is constructed in an entirely different way -- for our purpose we got to work with hex's but if anybody knows of some trick to kind of get a more blended effect that would be enormously appreciated. I'll give you a free copy of the game if interested.
I'm thinking something like plane that sits above the map, and some kind of light shifting shader with a grunge mask?
