Well I went back to the scene and made some changes, particularly the suggestion about the scrubby bushes (thanks Mr_Lamppost
. I used three different populations of grass as I couldn't find the right kind of bush I was looking for. I think it worked out. Changed the cloud layer and of course added the ruined Abbey from Loca Rodolfi's site @
http://www.rodluc.com/. I'm still bothered by the regularity of, not the rocks now, but the populations, maybe I just been looking at it too long!
Also I notice that the "Distribution Shader" doesn't have the "Intersect Underlying" feature of its big brother the "Surface Layer" so I could not get the populations to truly follow my grass shader from the previous render. Is this a feature that is pending for a latter release or is it something that is fundamentally not possible. Maybe in this instance I could use a surface layer instead?
As always C & C very welcome
Richard
