Hi, I need to fly the camera in Bryce 4 through a volume cloud slab, but whenever I render it the clouds flutter very rapidly. I have tried different speeds with no luck. the animation has to be 720 x 486 pixels at 72dpi. All I need is five seconds at 30fps. Can anyone help????? Thanks in Advance

I get fluttering weirdness when textures mapped to worldspace move in my animations. Mapping to objectspace or parametric and re-sizing seems to fix this.

In worldspace mapping the textures are fixed relative to Byce coordinates. When an object mapped this way moves, it sweeps the fixed texture map, giving the illusion of a moving texture. Try mapping with Object Space or any other system not related with world coordinates.
