well that answers that question.  i had tried to change the shape of the zone and couldn't find a way.  but you say that the influence will be spherical anyway.  doh.

 

i'm just gonna brute force apply magnets to create morphs i guess.  magnets give some flexibility i guess, just you have to use so many to be smooth and to get the shape just right.

 

so what was the shape changing technique for zones?  i tried exporting as obj, didn't take.  tried putting a magnet on zone, wouldn't take
