Hello, I have problems with seams in UE4, but in 3ds maps seems ok.
I tried bake normals in 3ds and Xnormal and have same result, what problem can it be? Please help
If u need some model information, I can give anything you want

-invert the green channel of your normal map → in the texture properties
-change the mode to normal → in the textur properties 
Of course I tried it. That was one of first potential problems. That’s why I baked it in Xnormal with -Y. Nothing changed.
The problem was to set compression settings for texture TC_normal.
