If you go to the Vue tutorials section there are some tuts on this by Guitta. Varian and Guitta both have alternate plant mats at their websites as well. Making the leaves invisible is an easy one. Open your material browser (button on the toolbar that looks like three spheres), edit the leaf mat you want to change, and set the transparency to 100%. Varian also has some excellent tuts on ways to use multiple trees together as one tree (you'll find his site through the Vue tutorial links as well). Rich
