Diagnal lines in my material displacement

I just started working in Unreal Engine 4 and I’m adding textures/materials to the level I’m making (first time texturing too), and I’m getting these strange lines in my material. Is there a way to avoid this/am I doing something to cause this? It keeps happening to me in the same spots no matter the material I’m using.
