not sure if this is the best spot, but here goes
what I need:
prim with center of rotation on one end, uni-directional growth (away from center of rotation), and flexi
I can get the first two easily, create sphere, start dimple 50%, convert to cube, double z-axis size.
but when turning on flexi, the prim snaps back to undimpled size, and has normal bi-directional growth (z-axis).
the size is no issue, but the bi-directional growth kills what I'm doing. is there a way, to change/workaround this behavior?
