Hi there. Thank you for your posts.

Redrobes : a lot of information there. Thanks for taking the time to put all that up! I'll explore those various options. I do like the rendered terragen cut away like that - I think Bryce can do the same thing?

Ascension: Yeah I had thought of that, but didn't try it because I didnt think I could get the intricate fractal like branch veins that are so distinctive on the DEM there. Do you have any examples? I'll like to see how it turned out for you.

SeerBlue: Yeah I found that site. I think I missed the registration bit. Probably why that when I explored the site it seemed to be showing fees no matter if I looked in country or not. I'll register and try again. That might be just what I'm looking for - thanks for the google tip too.

thanks for your help
