Ok, ok I know it's disrespectful and just plain wrong to decompile models, but I was wondering how in the world did you make the "orex" tree. I took one look at the polygon mesh and went "WHAT?" I guess you used an alpha texture for the tree, but am I right on the money or am I completely off? I also notice it has a rig, meaning it must be animated... but.. an animated tree? I just want to know how whoever made that tree went about doing that. I'm a fairly new modeler so I was wondering if I could learn.
The tree sways slightly, that's why it's rigged. The mesh is just a collection of large shapes with an alpha texture as far as I know, attached to a tree trunk and branches.
