Trees? Trees!
I successfully modified the Italian pine tree! I made it shorter and a bit wider. This is currently only a replacement because no programm can yet clone trees/shrubbery correctly. This is also why the textures aren't changed.
The foliage sways correctly in the wind and also the lower detail mesh works. This tree modding is currently very experimental! Also due to the special software used (a demo, very limited) it's very unlikely we're going to see many new custom trees/shrubbery. :(
