I have mirror model, that I made to save the size of textures. But in testing I see, that part of model, that must be flat, has a visible seams:
Normal map is configured to non-color, so it isn't a problem.
The problem, as I see, that there is no color in RGB that corresponds to
0.5, 0.5, 1.
#8080ff is bigger than this value, about
0.503, 0.503, 1 and
#7f7fff is less (about
0.498, 0.498, 1)
So now I found only one method to solve this problem - create a mask and mix them this way:
So is there a suitable method for using normal map on a mirror model?
