Hi Griggs, Thanks for the quick reply! I read further into this forum and found others are wondering about the trees too, and the rendering speeds. I should have looked before I wrote, but I was excited about the upgrade! I saw a posting called "What a waste", where the artist did a great rendering of a wine bottle and spilt wine (cute posting actually) and when I saw the wine, it dawned on me what metaballs can do! :>) Thanks for the link to the trees page, it will be most helpful! One has to wonder though why Corel didn't show the same intelligence as the author of those pages and give us good defaults for the trees to begin with! I sure hope Bryce will run faster for me on a new Mac! Between the software vendors and the hardware vendors, I am running just to catch up all the time, and money doesn't grow on trees, even Bryce ones (at least, I don't think so!). Still, it is a wonder that this stuff does as much as it does for the price, compared to the higer end 3-D modeling products and systems the "professionals" use. I also have Strata 3-D Pro (a very good program, and the basic Strata 3-D is free! But one would want Pro for the extra features) (http://www.strata.com), which lets me do complex models that I can bring into Bryce as DXF. There is very little I have seen in the Strata Galleries though that matches the quality of the work done by Bryce users! Thanks for the tips. CHU
