Stone Slab Alpha Texture doesn't look realistic

Request from Discord: "The only thing I found a bit awkward to use is the stone slab alpha texture.

The cutouts feel a bit… spaghetti-like, if that makes sense. It doesn't really look like the stones are naturally covered by something organic. To make it look realistic, I had to rely on a few blending tricks to make it look realistic, like using the non-alpha version more, overlaying ground textures, or covering parts with the grass line.

In comparison, the older "Rocks Alpha" texture from the desert pack feels more natural and easier to work with."
