set of texture stone walls made from my photos and edit in gimp to make tileable. Photos were taken in and around Campobasso (Italy)
Good job on the high pass, but the tiling is absolutely visible. You have to stamp away the hard lines through the image.
Also consider to re-color the image after the high pass by raising the contrast and saturation.
ok, thanks for the advise. it's difficult hide the tiling in the irregular surface without enlarge the image too much, I think I can make it better.... :-)
Grazie Mitch ottime texture, prover
