Has anyone ever made a tree system in Blitz that can make the distant tree switch to billboard sprites instead of fading out early. I've looked at a couple tree systems now and they both have the trees fading out as they go into the horison. Unfortunately, the trees can never get far enough away before they have to be faded out, or else your frame rate tanks. What I hate about that, is that it makes it look like there are no trees ever on the horison.

The Motorcross Madness 2 engine did the billboard sprite trick and it worked great! All they did was render a still of the tree in 3dsMax and put it on a sprite, and had it switch to it when it got to a certain distance. Then the sprite faded out eventually, but by that time, it was so far away, no one cared. The poping effect was hardly noticable!
