Well... isnt that cool. I'm going to answer my own post.
I have found out how you are supposed to make the tree lists, but i find that my graphics card drivers crash every so often so every 5 or so times i test it, windows has a cry.
Anyway here is the revised list, and this one works!
3
0 0 255 Trees\birch_adult\birch_adult.btr 5 5 5
0 255 0 Trees\pine1\pine1.btr 5 5 5
255 0 0 Trees\spruce_tall\spruce_tall.btr 5 5 5
So it creates an adult birch on a blue pixel, a pine on a green pixel, and a tall spruce on a red pixel.
Piece of cake really. Dont know why i didnt think of it sooner.
