Great! Thanks nruddock! I can't write code to save my life,lol, so it is wonderful that there are folks in the Modeling Forum who also have that talent. The only other prob I've run into with the prog is that the preset willow tree tends to get stuck at around 7% when it is exporting the model file in any of the formats available.The black oak is a little problematic too as it is so poly heavy that I haven't been able to import it into any rendering app.:-)
