This thread gives me ability to post something I always wanted to share for
inspiring somebody but couldn't because of photo nature ;-) Here are stone
stairs I made in my hause. The key of the design is that external edge has
doubled length of inner edge. To make it on-topic this was of course
visualized in POV-Ray before building.

just playing, can you try pattern 2, R=0.333, Crack=0.03
result looks slightly weird ? i was sort of expecting a brick wall
laid out flat
have you any suggested ranges for the various values ?

I have not really worked out a range of values. It is trial and error I
guess. In your example, the main culprit is Crack which draws the stones
apart. In combination with the size of the stones (determined by N), the
result will be more or less acceptable. In any case, keep Crack fairly low.
There are, obviously, some draw backs to the method I used <sigh>, but
overall, avoiding weird cases, works pretty well.

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! :-)
