LCBoliou, I got WB 3.6 from 3D World too! Great program. I did check out the Onyx software...a bit too expensive. I think eventually I will get Xfrog Lite. I will try to learn more about Carrara's tree editor. I wasn't impressed with the stock Carrara trees, but I didn't know you could improve them so much. I think the worst tree editor is Bryce 5's Tree Lab...totally unrealistic-looking trees, and even though there were about 60 different species, they all looked pretty much the same!
