I found you can get multiple textures on the tastiger tree by going into the grouping tool and seperating out the groups into materials. Also, while you're in there, spawn props a couple of times and twist the props on the Y to get a nice bushy tree. Then you can go into the materials editor and assign different mats for the bulbs(spheres) and lights (fountain), also for the needles, so you can have a more natural (or not) looking tree.
