Hi ,

 I just tried it again. I never really paid attention to it in detail. But Shuffle does not set from one key frame to the next. Opps. it only changes the entire set of frames. But The clouds do animate and change , If the clouds are static ,  that is the cloud does have a keyed motion  from one frame to the next  the cloud wont change . This is a 2 second animation at 6 frames a second just enough to see the cloud does change as it moves. I just set animation setting in cloud settings to 2 and moved the cloud to the right from keyframe 1 to the end and keyed again. Not drastic changes in the cloud but watch the ends carefully you will see them certainly change.

I Suppose there could be some improvements like being able to keyfram shuffle and changing the intensity of variation. Maybe we can ask daz to beef it up.

Sorry for the high compression its like 16megs uncompressed
