I gave Ryan Archer’s ‘Golden Forest’ tutorial a try; and, must say that it was a very informative lesson. I learned a number of techniques I wasn’t aware of. I also included his ‘Dirt and Soil Pack’ in this scene available at the NWDA site: ( http://www.nwdanet.com/home ) where his Golden Forest tutorial is also available. You can also get the tutorial at Ryan’s site: http://www.archer-designs.com/ . Some of the things I had to do differently were to eliminate the four populations of grasses suggested in the tutorial. Reason: several trace ray and populator errors. Additionally, I had to reduce the suggested rendered image size from 1600 x 1000 to 1280 x 800 in order to get a successful render. The prime reason for these issues is probably because I’m running a 32 bit OS with 4 GB of RAM and a quad-core processor. It was suggested that a 64 bit OS might eliminate the problem issues. I had also been informed that a 32 bit OS can handle up to 4GB of ram (usually 256-512MB are used by video which gives you 3.5-3.7GB) while a 64bit OS can go up to 8GB. Perhaps these are specific limitations of Terragen 2 – not sure. The trees include three different populations of Walli’s pines. The fourth tree/bush includes the ‘Pinus Negra’ which is the lighter colored plant in the scene. Bob PS - There is a forest preserve south of Chicago called 'Dan Ryan's Woods' ...FYI.
