Ok, so I've been searching this forum and have seen a VERY FEW mentions of this, but it always seems pretty vague... so I'll come right out and ask;   IS THERE ANY WAY TO MAKE TREES BEND, MOVE, RUSTLE, SWAY, OR IN ANY WAY act as if wind is affecting them  in Bryce  5.5 ?!?! 

I almost feel stupid asking this, because animating a tree to move slightly seems like a no-brainer for a 3D application, but I have been trying for days to figure it out or to find some answer on the web. Or at least has anybody found a reasonable "work around"?

Animating a scene where everything is moving except the trees looking rigid is pretty stagnant.  Any help, please?
