Hello, I got a problem with the normal map on a 3d model 
In blender, normal map works fine, we don’t see uv seams.
But when I display color of the normal map, uv seams are visible, this strange because normal render well
When I use this texture on unreal, the display is bad
I check if it was not a normal direction problem, but looks fine…
I edited the texture to make uv seams render well in color, but still don’t work on unreal …
Please help 
Sorry for my english
