...which reminded me that with matrix (shearing for instance) you can do 
interesting transformations to height_fields, even making overhanging rocks 
like in this example. No need for isosurface here :-)

Hi.

Add William Tracy's great vegetation macro to the surface of your rocks, 
that will fit and look gorgeous then!

Fog: make it a bit more transluscent, it seems to me to be too strong, a 
bit.
