animating clouds question

[Thejazzshadow]

I have been attempting to look at all the posts and still don't understand how to animate clouds. I am relatively new to Terragen 2 animating. Can someone tell me step by step what shader to parent to what so I can animate. Also, is it possible to do a tornado? (still or animated) just curious.

Use the Transform Shader in-between the Cloud Shader and its Density Shader and adjust X, Y, Z parameters for Translate and/or Scale (Transform would be best). This will move the noise function that defines the density of the cloud and thus the cloud shapes. Animating along the Y axis will move the noise function in the vertical, which acts somewhat like cloud "evolution" in practice.

Passable attempts at tornadoes have been accomplished (probably something would turn up in a search of the forums), but I doubt you could animate it convincingly.
