Thanks!
what got me interested most is that the terrain I tried it on in the fourth image is actually olympus mons, made with the same image map displacement I use for all my Mars- images. It didn´t seem to work with the Mola-map shader, wich cannot be rotated with the planet as far as I know, so a square around 0/0/0 wouldn´t show much anyway. I really hope that in future versions the erosion can be applied more flexibly (it´s fantastic as it is, but just for my very special aproach of a whole Mars it´s not yet useful)
But let´s see where it goes.
Until then, I´ll experiment with smaller pieces.
Cheers,
