Alpha texture in landscape material

I am trying to make a grass path edge using an alpha texture in the landscape material. I can’t figure out if there is a way to make the alpha texture appear only on the edge of the brush no matter the size or shape of the path I paint. Right now it just follows the texture and I end up with grid patterns so I can’t make curvy snaky paths.

I have tried multiple different alpha textures to see if I could at least get it close but have decided there has to be a way to do it from the blueprint or it’s just not possible, I don’t know. Any ideas of how the texture should be made or how to manipulate the coordinates of the texture so it lines up with the grass leading into the path would be greatly appreciated.

Also this material was from the Stylized Forest pack from the Marketplace I just customized it a little.

This is the blueprint. Currently the alpha is just set to scale with the path texture.
