I have an altar model that I want to texture. I have visible seams, but I paint over them. It appears correct when a map is in the Color node (diff/normal). I save the painted over image, but when I reload as Normal Map Color node, the seams are there, and they are pretty obvious. I've done the same with the normal map (just smudging the seams but it does appear seamless when the map is in Color). Any clues?
