This is a follow up to my quicktips regarding falloffs for vertex maps (vimeo.com/26734948 and vimeo.com/26568353) which are now obsolete as I've found a way to do this without
any xpresso but with a PoseMorph Tag.
All you have to do is to record two states of your vertex map. One is 0% weighting and one
with 100%. Then, by utilizing a PoseMorph Deformer one has full falloff control over the vertex map.
(I accidently selected the selection command first in the video, sorry for that :-)
