Turning trees in Unity Free

Hi,

I've created a real great terrain with trees from the "terrain assets. The problem is that the trees turn when go for a walk across the terrain. This isn't a real realistic effect. Why does this happen and what can I do to stop it?

Thanks for the answer,

Far-away trees are rendered as 2D billboards. Billboards will be updated automatically to orient themselves to the camera. Use Billboard Start to adjust the distance from the camera that trees will start appearing as Billboards instead of Meshes.

(from the Terrain Engine Guide)

also make sure you have the wind setting turned off for the tree's. I believe it's called "bend"
