can anyone point me in the right direction here? I’m trying to find out what causes these artifacts (pictured).
As the top face of my mesh approaches the landscape (along the Z plane) I get diagonal lines. These lines move with the mesh when shifted along X or Y axes (even with a world aligned texture) and fade away as I move the mesh up on the Z axis. I have the same result on Static Meshes that I create and unwrap in Blender as I do on BSP Geometry converted to a Static Mesh in UE4. It does not occur on BSP Geometry - only when I convert it to a static mesh.
