As title said, normalmap made from Substance Painter in Unity disorted. Here is the picture:
I made red rectangles to see more cleary. You can see that the some of line of normal were disorted obviously.
I have no Idea why this happens. Model made from Blender 2.78c and exported as FBX. Used Substance Painter 2017.3.3 and tested in Unity 5.6.x and 2017/2018.1.f1.
Any advice will very appreciate it.
