Thanks efflux for your reply. I am not privy for the use of the blue nodes; and, certainly appreciate what you have and others have shared here. My use of Terragen started almost ten years ago with 'Classic' where creations appeared as somewhat ethereal but beautiful ...had loads of satisfactory images - but, were lacking in having the fine details of what TG2 eventually offered.
I'm looking forward to continued learning; and, will be trying to incorporate you setup in future projects ...thank you again.
