Here is scripting and sculpting mastery in one package. The tree is ONE prim, and has 9 different varieties: styles of leaves, branches, trunks, flowers. You can change the tree at will, when the seasons or your mood changes. The detail is very cool, and the builder/artist has different sizes as well. Just the greatest ! $250 5/17/09
