How do I stretch a material effectivly

Hi, I just purchased the free Material pack from the UE4 Marketplace, and obviously intended to use them right away. The thing is, when I apply one, let’s say the Ground_GrassThickGreen material, the result is a overdimensional tiled texture (picture below). From my short time with UE4, i learned that this issue can tipically be resolved by adding (or in this case, modifying) a TexCoord, but it still does not appear as it should. Any ideas?

If you want to fix it inside a material you could multiply the texcoord node with a value before plugging it into the sampler. in this case you want to scale it up, so you would need someting like 0.01.
