Cheers guys, thanks for the feedback
I'm refining the displacements now, using two warped voronois on top of each other. I couldn't work out why I could not warp the voronois before, found out I was using the wrong "get" function. I had been using a simple "get position", it has no effect however "get position in texture" works well enough, other "get" functions may work as well.
For now I'm not working on the vegitation, laptop won't handle it and I want to concentrate on the landscape first.
I would like to have a go at the "Home Tree",might be a good re-introduction to XFrog (when I get my "key" back lol)
Oh and James, I'm sure we can work out something, you can have half (well maybe 10%) of any money I make from this picture
Thanks
Richard
