I was following the 3D tuts here and made my little game with the race cars and tires. I tried added adding trees to the outside but all my depths got screwed up… The trees are in front of the tires, the tires are in front of the car…:(. Plaese Help!

Can you find the error?
Thanks, sorry no fla. My server can’t handle it…
