Issue terrain texture UE4

SuSo

Hi everyone! ^^

I have a little problem with the texture in UE4 and i don't know how to fix it.

The texture created by me, it should look like the first image, but, one time is used in my environment, you can see the quality of it is worse, i don't know if is the angle of the camera or what, i've tilled it too, but i've changed the parameter of the images to sharpen10 and the results are the same.

In this time, i'm stuck because i don't know  what's happening

Thanks a lot!

The first one is how the image should look

How looks in the environment
