Problem with imported meshes from blender

So I tried to make a wedge in blender as there wasn’t one in UE4 as stock and then, after all was done encountered a problem with materials.

How could i make it so that the lines align like with other objects on my thingie?

You need to correctly UV unwrap the model in blender. Google around for UV unwraping tutorials in blender, there are plenty. Good luck.
