I’ve been having a very strange and unique problem that no matter what I do seems to persist in UE4. I’m a 3d artist and have a very basic grasp of UE4 and so I have probably missed something more experienced users will probably pick up on.
My problem is that parts of my emissive and normal map seems to be missing after setting up applying my material to the mesh as seen in the included picture. I have tested the mesh and its textures in Unity5, Maya, Max, Marmoset and Subtance Painter from which I exported the maps from. Its works fine in everything else and this problem is unique to UE4 and to be honest Im confused and stuck.
