Square Tiling HELP

Okay so I’ve been stumped and looking for just a simple answer. I am trying to make a cobblestone path on my terrain and it be perfectly drawn to actually look like a path, not a path with fading on the edges (doesn’t look realistic). So, is there any way to make the fade disappear. and just completely cut off the texture.

I just want it to paint where the blue square is not all the extra around it, please Help. I feel dumb not being able to figure this out…

You may have to increase the Control texture Resolution of your terrain to increase the hardness of the transition.
