Hi!

3dcafe.com has a lot of free dxf and 3ds models of trees and plant, which can 
be imported into radiance. If you use them as instances and exclude them from 
ambient calculation, you can use lots of these detailed geometries. Take a 
look at the rpict options for this, don't even think about doing ambient 
calculation of detailed trees' geometries! The placement of tree and plant 
instances can be done in a very comfortable way if you use a markers file, 
you simply make a cad-triangle and copy this to the desired locations, using 
one layer for every plant/tree type, rotate some of them randomly and take a 
look at replmarks. BTW, if you have access to rayfront, this tool handles 
marker files in a frontend.

However, the representation of grass might be a bit difficult.... they HAVE 
3d-geometry ;-) But maybe one should use a cal file to create the grass 
geometry, or does it make sense to get brd-data for grass???

Good luck, CU, Lars.
