How can I make the tornado rotate superfast?...On a small 9 sec animation, I've got 2 frames...First frame Y-rotate=0, 2nd frame Y-rotate=999...the rotation is superslow with this! i read somewhere about amplification...any link there? all opinions appreciated!

there's no motion blurr in bryce so more then 180 degrees rotation per frame creates an effect that looks like the tornado is spinning backwards and at more then 360 degrees rotation it starts looking like it's rotating forwards again and so forth. Your tornado looks like it's spinning backwards with 99 degrees per frame. You could change the texture of your tornado to make it look like it's already motionblurred and then animate the texture and rotate your model slightly to create the larger movements. flying debris will also make the effect more dramatic. If you look at real tornado footage(sp?), you don't see the tornado spinning almost 41.625 times per second.

thanx for the reply!...So if I get this right, what u're saying is that I can only make the tornado seem to rotate fast using: a) blurry texture b) use props such as debris it cannot, however, rotate faster by using any other means...am i on the right track? what do u mean by "animate the texture" and "rotate your model slightly to create the larger movements"? your answers wud be greatly appreciated, as always!

You are correct. You can let the object spin faster, but because an animation is build up out of frames it looks like it's spinning slowly or backwards. It's a bit like the wheels of a car: When a car starts driving you see the wheels turn, but as the car goes faster the weels seem to slow down again and even rotate backwards eventually and if the rotation speed keeps increasing they can seem to slow down again and go forward and then slow down again etc. When you use a higher frame-rate you can give more detail to your animation and you can rotate the object faster, because there are more frames to render the rotating object. But ofcoarse there's a limit to this because the human eye also has a refresh-rate. Animate the texture: You can animate the phase, noise etc. of the texture in the DTE to create the effect of 'morphing'dust-clouds. This works best with fuzzy or volume textures, wich are probably the textures you are using. rotate your model slightly to create the larger movements: I find it hard to explain this in english, ut I'll try: If you look at a real tornado it doesn't really seem to move really fast unless it's up close like in some scenes of the movie twister. You can create the effect of fast movement with the 'morphing' and blurred and maybe even rotating textures. The movement of the tornado over the terrain and the trunk(is this how you call it in english?) that could for instance bend, get wider or smaller are what I meant with the larger movements. They are less detailed and more subtle.

What might help you with visualizing how this works is to fill a tall glass with water and add some lightweight objects like small plastic toys. Then you can stir the water in the glass to see how the objects move inside of the swirling. This tornado sounds interesting - good luck getting the effect you want. Lin
