To get good trees you have to go into the tree lab and fool with the controls. To get there select the tree then clcik the little "e". http://www.brycetech.com has a good tutorial on what the different settings do. If you have the 5.01 patch hold down the alt key when clicking on the create tree icon and a load window will appear with some fairly good tree presets. If you create a tree in the tree lab that you like you can select that tree then ctrl click the create tree icon and save the tree. Also many people have done some trees with settings on websites (can't find the URL right now) or in the freestuff or the marketplace.
