Tutorial - Adding Trees to Zones (2 methods)

[Sakrateri]

Ok, that works for single textured objects such as grass and weeds as you can see in this picture





but for things like trees with a leave and bark texture its not so good. I can only use one of the textures. I made these trees in 3dsmax, would i need to make the trunk and leave part seperate?? thanks for the help Scorp.
