cheers Henry and Marc...the first one had a strata and outcrops shader, but it was not showing/working, this uses no strata, just massive voronoi of different scales and some merge shaders with power fractals as mixers, I have tried to add smaller scale details, but it is difficult to get the right mix, I will persevere and continue to tinker/experiment, as I like this terrain, it seems to work well at this massive scale...I will travel about a bit to see what happens elsewhere on the planet, also try some different terrain fractals etc!
