Particularly if the clustered could: (a)be assigned a bodypoint that would show up in the keyframe editor as the root to drag the whole lot around with one set of translation controls, simplifying the pathing task, and... (b)there was some way to define a field of movement about that bodypoint, where random XYZ shifts could be defined (all values being input fields, so that the size of the field could be set to match scene requirements). Or each added object sets itself in frame 1 with it's creation point automatically becoming its 'null' position, and the random motions being defined by percentage of shift across each axis (and a simple number generator to vary the speed of the displacement across a chosen time frame), to allow some cluster objects more XY displacement while some have XZ and others YZ. That would break the gross repetitive 'look' that you can get with automated scripting. (Thinking animated firefly scatters here, where you would have some doing vertical climbs with little horizontal displacement, the occasional cowboy zipping horizontally acrosss the group) And I chose the nano-atomic reference deliberately... :P Massive is quite well beyond, true enough...but one thing that gets overlooked a lot in the 'Rings' movies is that it wasn't just Massive; they used the -entire- bag of movie tricks, from forced perspective up. And while Poser alone couldn't really do too many of them due to the way things work, Poser and something like VuePro could.
