You know, your example happens sometimes in the real world. Very old,
abandoned pavements may have much enlarged cracks because of vegetation
growth between the stones. So, it would be interesting to use it in
combination with growing grasses in a derelict premise. Idea for a scene,
isn't it?

ok, thought lets try a patio type size - square blocks

N=10, R=1 no other changes

anyone got a soil textute for a height field ?

Many thanks and congratulation, Thomas Le Grand !

It is EXACTLY what I need for the scene I have currently in workshop (see
attachment). I will try it as well for walls on old filthy buildings.

Thank you! Glad it proves to be useful. Yes, I think it could easily be
applied on walls too!
Oh! Good translation of my name, by the way! :-)
