Sharp

Hello, I am trying to make a top-down game with a pixel art style and I have run into a problem. I have a landscape set up with pixel art textures for dirt, grass, sand, etc in it. But, they all have smooth fall off’s, even with 0% brush fall off, 100% strength and my attempts at changing the landscape resolution. This is a problem because I want to make a dirt path that goes to different areas, and it is not sharp at all, it looks awful.

I’ve included some photos, including the texture I am using as a height blend for the dirt path. Any help would be appreciated.
