Hi Craig,
Thanks I’m fine, I hope you as well!
You said you know the PBlurb, so I shouldn’t start there, but it is a forum and some might be new to it. The PBlurb works like two explosion effects with the particles flying from a to b (or vice versa). It is by no means a polygon morph effect. A reason why I point this out is simple, and I guess you know it already, it is an illusion. To my knowledge there is no option that would take polygons from one object to the next, and keep triangles and quads separated as well duplicating polygons if needed (or dividing)
The question would be—is the “particle stream” the part you are after or is it a morph effect?
I mentioned it before, we are magicians when it comes to effect animations. It is not so much to do it as in reality, it is more to do it believable. Having said that, how about that: You split the Brain in three parts (as you said it should go into three Butterflies). Then you use the Camera deformer to one of the three parts of the brain and pull it to the butterfly one, a little bit more than half the way. The butterfly itself becomes treaded in the same way, but reverse with a new Camera Deformer. To get this effect more manageable I would not suggest to use PLA (Point Level Animation)—I would suggest to go for each “state” of the deformation with a PoseMorph>Pose. The points of the camera deformer can be dragged with a Magnet, and if done nicely with the PoseMorph (set to points) you can direct your scene beautifully. (Set the amount of segments in the Camera Deformer before you start working with them! No Change in count after the Pose Morph is working for you.)
There is nothing that speaks against adding a PolyFX to the mix. (Magicians use distractions to cover the needed steps… ;o)
I hope that makes sense.
The beauty of the CameraDeformer is given in its easy way to use, and its interactive way of deforming objects dramatically. Perhaps you give it a shot.
All the best

The file shows the transition, or better no transition from Sphere to Cube, just by dissolving via polygon. With the right amount of movement no problem.
