Can anyone tell me why Some parts of my material as significantly darker than the rest ? It has to do with the normal map and is not visible in marmoset itself only in the viewer.
To give some background info, I've painted everything in substance painter and exported it using the specgloss from metalrough. Inverted the Y as recommended, enabled sRGB.
to perhaps make it easier I've included several screenshots.
See the darker parts
