How can I blend these two materials in Painter seamlessly?

I have a dirt texture and a grass underlay texture, but blending these with a mask creates a horrible looking transition, if I use a dirt brush instead of a solid brush it looks even worse. How can I blend them correctly?

Looks like your dirt has a higher height than the grass, you should bew able to tweak that in the dirt material or add a levels to it to lower the height.

Thanks Jerc, I ended up vertex blending it in UE4 so I could keep all the exposed parameters for tweaking.
