just try building one, or use mission editor, or use the stranded rp
Squideey or Eksi posted a picture of their trees one of them made in a topic, which was pretty sweet and real looking, just try to make a tree..
i actully have that squideey gave it to me (well let me save) and i dont use it that much
i just macro my trees, also, i thought blockland was a game of plastic legos, not a realistic looking game?
