Thanks Frank, completely don't mind your input on this, I have PF plugged into the color and displacement inputs in the surface layers, The noise is at its default Perlin however, I also cut the features scale on the PF to help the rock, it doesn't look right and I couldn't figure out why. Displacements as you mentioned might turn this in the right direction
Heres another update, mostly on scaling of the plants, and the smaller scaled PF and deleted one rock layer as its looks to built up in the previous render
Thanks
