I have ran into an issue where if I enable cast shadow on my mesh I can see some of the geometry of my low poly model even though I have a normal map applied to it, when I disable cast shadow it fixes the geometry but then it will never cast any shadows. I am somewhat new to UE4 and blender so I have no idea how to fix this and I have been trying for hours, the only thing I have seen to try and fix it was to flip the green channel but it didn’t work.
the normal map if that helps in anyway.
