allright, finally got it managed to get both, the mason lines and the displacement from the last pic, mixed together. sometimes the most obvious is the hardest to find, i just divided the powerfractal that drives the perlin scale by another powerfractal, same values, different seed.
don't know if it's looking good at all, stared too long on my monitor i think, lol *runs off for a break*
still got this strange structures on the ground, but i'll leave that for now
