I'm trying to animate a landscape in Bryce 5. It's a type I've done successfully before, a flowing river, but this time I have 2 problems I haven't been able to solve. The only thing I animated is the water, but the hills in the foreground sort of quiver and either they change position or the camera changes position by the end of the ten seconds. I've removed all keyframes and checked in the Animation Lab and can't find any, so why is anything moving? Thanks.
