Blurred terrain textures after UniStorm import

I have a problem. In my project I have a scene with a terrain and before I imported UniStorm, the terrain looked fine. Then after I import UniStorm into my project, the terrain’s textures (all of them) look really blurry, even when close up and its not a problem with the texture.
