Texture change due to sunlight

Ok, so I am working on a mod, and it has been giving me this weird texture for the roads, and I'm not quite sure why. It almost seems as though my grass texture is appearing on the road, and this has been happening on all my roads for a couple of days. (Whenever I try to create a new decal road) The thing is, this texture goes away when sunlight isn't shining on it. I'm not sure if this has to do with my normal's or anything, but I cannot seem to fix it. Also when I go into material editor and make it emissive, it goes away. Not sure whats happening, but any help would be greatly appreciated. I have a picture below of what happens.
