sorry the links for BB matmathic are broken:-(
(was in a rush when I posted links but have looked on wayback when I got home but no joy )
in the freestuff the texture by fictionalbookshelf is pretty good has some probs at seams and edges but I have it tiling in blender so maybe with some time in paint proggy it can be sorted, I'm looking at armour for dogs so was wanting chainmail anyhow ;-)
pic is dog with its chainmail on and NOOOOOOOO its NOT a red setter just wanted to show off the transmap lol
